Peach


Peach is a tree that at first grew in China. Peaches are also the fruit the peach tree makes. Peaches are called stone fruits because they have a shell of hard wood around their seed, called a stone or a pit. Cherries, plums, and apricots are other stone fruits. There are two types of peaches: freestone and clingstone. Freestone peaches do not stick to their pits, while clingstone peaches do.

The skin of a peach is an orange-yellow color, and it is covered in small, fine hairs called peach fuzz. A peach without the fuzz is commonly called a nectarine. The inside of a peach is a golden color. The inside of a peach is sweet and sticky. Because they taste sweet, peaches are often part of dessert.

Many North Americans enjoy this fruit, as well as others all over the world.

Peaches are often confused with nectarines, the difference is that a peach has fine and small hairs, (peach fuzz) but a peach with no fuzz is a nectarine. Peaches are grown all over the world these days but they are now becoming very expensive. In Peru, peaches are cald panigwats, (meaning sweet fruit). Scientists say that peaches are so rare that the species of the peach might get wiped out1

Jujube


Ziziphus zizyphus (from Greek ζίζυφον, zizyfon), commonly called Jujube, Red Date, or Chinese Date, is a species of Ziziphus in the buckthorn family Rhamnaceae, used primarily for its fruits.

Distribution

Its precise natural distribution is uncertain due to extensive cultivation, but is thought to be in southern Asia, between Lebanon, northern India, the Korean peninsula, and southern and central China, and also southeastern Europe though more likely introduced there.

Growth

It is a small deciduous tree or shrub reaching a height of 5–10 m, usually with thorny branches. The leaves are shiny-green, ovate-acute, 2–7-cm wide and 1–3-cm broad, with three conspicuous veins at the base, and a finely toothed margin. The flowers are small, 5-mm wide, with five inconspicuous yellowish-green petals. The fruit is an edible oval drupe 1.5–3-cm deep; when immature it is smooth-green, with the consistency and taste of an apple, maturing dark red to purplish-black and eventually wrinkled, looking like a small date. There is a single hard stone similar to an olive stone.


Nomenclature


The species has a curious nomenclatural history, due to a combination of botanical naming regulations, and variations in spelling. It was first described scientifically by Carolus Linnaeus as Rhamnus zizyphus, in Species Plantarum in 1753. Later, in 1768, Philip Miller concluded it was sufficiently distinct from Rhamnus to merit separation into a new genus, in which he named it Ziziphus jujube, using Linnaeus' species name for the genus but with a probably accidental single letter spelling difference, 'i' for 'y'; for the species name he used a different name, as tautonyms (repetition of exactly the same name in the genus and species) are not permitted in botanical naming. However, because of Miller's slightly different spelling, the combination correctly using the earliest species name (from Linnaeus) with the new genus, Ziziphus zizyphus, is not a tautonym, and therefore permitted as a botanical name; this combination was made by Hermann Karsten in 1882

Cultivation and uses

Jujube was domesticated in the Indian subcontinent by 9000 BCE.[3] Over 400 cultivars have been selected.

The tree tolerates a wide range of temperatures and rainfall, though it requires hot summers and sufficient water for acceptable fruiting. Unlike most of the other species in the genus, it tolerates fairly cold winters, surviving temperatures down to about −15°C. This enables the jujube to grow in desert habitats, provided there is access to underground water through the summer. Virtually no temperature seems to be too high in summertime.

Medicinal use

The fruits are used in Chinese and Korean traditional medicine, where they are believed to alleviate stress.[citation needed] The jujube-based Australian drink 1-bil avoids making specific stress-related claims, but does suggest drinking 1-bil "when you feel yourself becoming distressed".

Ziziphin, a compound in the leaves of the jujube, suppresses the ability to perceive sweet taste in humans.The fruit, being mucilaginous, is also very soothing to the throat and decoctions of jujube have often been used in pharmacy to treat sore throats.

Culinary use
Dried jujube fruits, which naturally turn red upon drying.

The freshly harvested as well as the candied dried fruits are often eaten as a snack, or with tea. They are available in either red or black (called hóng zǎo or hēi zǎo, respectively, in Chinese), the latter being smoked to enhance their flavor. In mainland China, Korea, and Taiwan, a sweetened tea syrup containing jujube fruits is available in glass jars, and canned jujube tea or jujube tea in the form of teabags is also available. Although not widely available, jujube juice and jujube vinegar (called 枣醋 or 红枣醋 in Chinese) are also produced. They are used for making pickles (কুলের আচার) in West Bengal and Bangladesh.

In China, a wine made from jujubes called hong zao jiu (红枣酒) is also produced.Jujubes are sometimes preserved by storing in a jar filled with baijiu (Chinese liquor), which allows them to be kept fresh for a long time, especially through the winter. Such jujubes are called jiu zao (酒枣; literally "spirited jujube"). In Korea, jujubes are called daechu (대추) and are used in teas and samgyetang. It is said to be helpful in aiding the common cold.

In addition, jujubes, often stoned, are a significant ingredient in a wide variety of Chinese delicacies. In Persian cuisine, the dried drupes are known as annab.

In Tamil-speaking regions, the fruit is called ilanthai pazham (இலந்தை பழம்). Traditionally, the fruits are dried in the sun and the hard nuts are removed. Then, it is pound with tamarind, red chillies, salt, and jaggery. Small dishs are made from this dough and again dried in the sun, and are referred to as ilanthai vadai.

Other uses

The jujube's sweet smell is said to make teenagers fall in love, and as a result, in the Himalaya and Karakoram regions, men take a stem of sweet-smelling jujube flowers with them or put it on their hats to attract women.[citation needed]

In the traditional Chinese wedding ceremony, jujube and walnut were often placed in the newlyweds' bedroom as a sign of fertility.

In Bhutan, the leaves are used as a potpourri to help keep the houses of the inhabitants smelling fresh and clean. It is also said to keep bugs and other insects out of the house and free of infestation.

In Japan, the natsume has given its name to a style of tea caddy used in the Japanese tea ceremony.

In Korea, the wood is used to make the body of the taepyeongso, a double-reed wind instrument. The wood is also used to make go bowls.

In Vietnam, the jujube fruit is eaten freshly picked from the tree as a snack. It is also dried and used in desserts, such as sâm bổ lượng, a cold beverage that includes the dried jujube, longan, fresh seaweed, barley, and lotus seeds.

Apricot


The Apricot (Prunus armeniaca, "Armenian plum" in Latin, syn. Armeniaca vulgaris Lam., Armenian: Ծիրան "Tsiran") is a species of Prunus, classified with the plum in the subgenus Prunus. The native range is somewhat uncertain due to its extensive prehistoric cultivation, but most likely is India

Description
It is a small tree, 8–12 m tall, with a trunk up to 40 cm diameter and a dense, spreading canopy. The leaves are ovate, 5–9 cm long and 4–8 cm wide, with a rounded base, a pointed tip and a finely serrated margin. The flowers are 2–4.5 cm diameter, with five white to pinkish petals; they are produced singly or in pairs in early spring before the leaves. The fruit is a drupe similar to a small peach, 1.5–2.5 cm diameter (larger in some modern cultivars), from yellow to orange, often tinged red on the side most exposed to the sun; its surface is usually pubescent. The single seed is enclosed in a hard stony shell, often called a "stone", with a grainy, smooth texture except for three ridges running down one side.

Cultivation and uses
The Apricot was first cultivated in India in about 3000 BC. In Armenia it was known from ancient times - it has been cultivated there so long it is often thought to be native there.. An archeological excavation in Armenia found apricot seeds in an Eneolithic-era site. [7] Its introduction to Greece is attributed to Alexander the Great,and the Roman General Lucullus (106-57 B.C.E.) also exported some trees, cherry,

white heart cherry and apricot from Armenia to Europe. Subsequent sources were often much confused over the origin of the species. Loudon (1838) believed it had a wide native range including Armenia, Caucasus, the Himalaya, China and Japan.

Nearly all sources presume that because it is named armeniaca, the tree must be native to or have originated in Armenia as the Romans knew it. For example, De Poerderlé asserts: "Cet arbre tire son nom de l'Arménie, province d'Asie, d'où il est originaire et d'où il fut porté en Europe ..." ("this tree takes its name from Armenia, province of Asia, where it is native, and whence it was brought to Europe ...") There is no scientific evidence to support such a view. Today the cultivars have spread to all parts of the globe with climates that support it.

Apricots have been cultivated in Persia since antiquity, and dried ones were an important commodity on Persian trade routes. Apricots remain an important fruit in modern-day Iran where they are known under the common name of Zard-ālū (Persian: زردالو).

Egyptians usually dry apricot and sweeten it then use it to make a drink called "'amar al-dīn".

More recently, English settlers brought the apricot to the English colonies in the New World. Most of modern American production of apricots comes from the seedlings carried to the west coast by Spanish missionaries. Almost all U.S. production is in California, with some in Washington and Utah.

Many apricots are also cultivated in Australia, particularly South Australia where they are commonly grown in the region known as the Riverland and in a small town called Mypolonga in the Lower Murray region of the state. In states other than South Australia apricots are still grown, particularly in Tasmania and western Victoria and southwest New South Wales, but they are less common than in South Australia.


Cultivation

lthough often thought of as a "subtropical" fruit, this is actually false – the Apricot is native to a continental climate region with cold winters, although it can grow in Mediterranean climates very well. The tree is slightly more cold-hardy than the peach, tolerating winter temperatures as cold as −30 °C or lower if healthy. The limiting factor in apricot culture is spring frosts: They tend to flower very early, around the time of the vernal equinox even in northern locations like the Great Lakes region, meaning spring frost often kills the flowers. Furthermore, the trees are sensitive to temperature changes during the winter season. In their native China, winters can be very cold, but temperatures tend to be more stable than in Europe and especially North America, where large temperature swings can occur in winter. The trees do need some winter cold (even if minimal) to bear and grow properly and do well in Mediterranean climate locations since spring frosts are less severe but there is some cool winter weather to allow a proper dormancy. The dry climate of these areas is best for good fruit production. Hybridisation with the closely related Prunus sibirica (Siberian Apricot; hardy to −50°C but with less palatable fruit) offers options for breeding more cold-tolerant plants.

Apricot cultivars are most often grafted on plum or peach rootstocks. A cutting of an existing apricot plant provides the fruit characteristics such as flavour, size, etc., but the rootstock provides the growth characteristics of the plant. Apricots and plums can hybridize with each other and produce fruit that are variously called pluots, plumcots, or apriums.

Apricots have a chilling requirement of 300 to 900 chilling units. They are hardy in USDA zones 5 through 8. Some of the more popular cultivars of apricots include Blenheim, Wenatchee Moorpark, Tilton, and Perfection.

There is an old adage that an apricot tree will not grow far from the mother tree. The implication is that apricots are particular about the soil conditions in which they are grown. They prefer a well-drained soil with a pH of 6.0 to 7.0. If fertilizer is needed, as indicated by yellow-green leaves, then 1/4 pound of 10-10-10 fertilizer should be applied in the second year. Granular fertilizer should be scattered beneath the branches of the tree. An additional 1/4 pound should be applied for every year of age of the tree in early spring, before growth starts. Apricots are self-compatible and do not require pollinizer trees, with the exception of the 'Moongold' and 'Sungold' cultivars, which can pollinate each other. Apricots are susceptible to numerous bacterial diseases including bacterial canker and blast, bacterial spot and crown gall. They are susceptible to an even longer list of fungal diseases including brown rot, Alternaria spot and fruit rot, and powdery mildew. Other problems for apricots are nematodes and viral diseases, including graft-transmissible problems.

Etymology
The scientific name armeniaca was first used by Gaspard Bauhin in his Pinax Theatri Botanici (page 442), referring to the species as mala armeniaca "Armenian apple". Most believed and many still believe that it came from Pliny the Elder; however, it is not used by Pliny or any other classical author, even in Late Latin. Linnaeus took up Bauhin's epithet in the first edition of his Species Plantarum in 1753.[15] A popular name for this species is apricock.

The epithet probably is derived from an etymological identification of a tree mentioned in Pliny with the apricot. Pliny says "We give the name of apples (mala) ... to peaches (persica) and pomegranates (granata) ...."[16] Later in the same section he states "The Asiatic peach ripens at the end of autumn, though an early variety (praecocia) ripens in summer - these were discovered within the last thirty years ...."

From this praecocia comes the standard etymology of "apricot". The classical authors connected armeniaca with praecocia: Pedanius Dioscorides' "... Ἀρμενιακὰ, Ῥωμαιστὶ δὲ βρεκόκκια"and Martial's "Armeniaca, et praecocia latine dicuntur".Putting together the Armeniaca and the mala obtains the well-known epithet, but there is no evidence the ancients did it; Armeniaca alone meant the apricot.

Accordingly the American Heritage Dictionary under apricot derives praecocia from praecoquus, "cooked or ripened beforehand", becoming Greek πραικόκιον "apricot" and Arabic al-barqūq "apricot" (although in most of the Arab world the word now means "plum"). The English name comes from earlier "abrecock" in turn from the Middle French abricot, from Catalan abercoc.Both the latter and Spanish albaricoque were adaptations of the Arabic, dating from the Moorish occupation of Spain. However, in Argentina and Chile the word for "apricot" is damasco, which probably indicates that to the Spanish settlers of Argentina the fruit was associated with Damascus in Syria.

The anecdotal evidence is the only link between the apricot and Pliny's tree, but even if true, the origin of the word is not the origin of the tree. The Romans had no idea why the tree was called armeniaca and presumed as did later botanists that it was "from Armenia", whatever that should mean. Scientifically nothing at all about the evolution or production of the wild tree or any of its cultivars or about the native range at the time of the Romans or any other time in history is implied. At best the tradition reflects Roman literary opinion concerning some now obscure

Blackberry


The blackberry is an edible berry in the Rubus genus and the Rosaceae family. The fruit are botanically termed an aggregate fruit and they are produced on plants that typically have biennial canes and perennial roots. Blackberries and raspberries are also called caneberries or brambles. It is a widespread, and well known group of over 375 species, many of which are closely related apomictic microspecies native throughout the temperate Northern hemisphere and South America

In its first year, a new stem, the primocane, grows vigorously to its full length of 3-6 m (in some cases, up to 9 m), arching or trailing along the ground and bearing large palmately compound leaves with five or seven leaflets; it does not produce any flowers. In its second year, the cane becomes a floricane and the stem does not grow longer, but the flower buds break to produce flowering laterals, which bear smaller leaves with three or five leaflets.[2] First and second year shoots are usually spiny with numerous short curved very sharp thorns (thornless cultivars have been developed purposefully). Recently the University of Arkansas has developed primocane fruiting blackberries that grow and flower on first year growth much as the primocane (also called fall bearing or everbearing) fruiting red raspberries.

Unmanaged mature plants form a tangle of dense arching stems, the branches rooting from the node tip on many species when they reach the ground. Vigorous and growing rapidly in woods, scrub, hillsides and hedgerows, blackberry shrubs tolerate poor soils, readily colonizing wasteland, ditches and vacant lots.[1][3]

The flowers are produced in late spring and early summer on short racemes on the tips of the flowering laterals.[2] Each flower is about 2-3 cm in diameter with five white or pale pink petals.[2] The newly developed primocane fruiting produces flowers and fruits on the new growth.

The early flowers typically form more drupelets than the later ones as they develop more fully as the flower buds develop during the dormant period. This can also be a symptom of exhausted reserves in the plant's roots, marginal pollinator populations, or infection with a virus such as Raspberry bushy dwarf virus. Even a small change in conditions, such as a rainy day or a day too hot for bees to work after early morning, can reduce the number of bee visits to the flower, thus reducing the quality of the fruit. The drupelets only develop around ovules that are fertilized by the male gamete from a pollen grain.

In botanical terminology, the fruit is not a berry, but an aggregate fruit of numerous drupelets ripening to black or dark purple.

Blackberry leaves are also a food for certain caterpillars and grazing mammals, especially deer, are very fond of the leaves. See List of Lepidoptera that feed on Rubus

Cultivation and uses
Primary cultivation takes place in the state of Oregon located in the United States of America. Recorded in 1995 and 2006: 6,180 acres (25.0 km2) to 6,900 acres (28 km2) of blackberries, producing 42.6 to 41.5 million pounds, making Oregon the leading blackberry producer in the world.[4][5]. While Oregon may lead the world in volume of fruit produced, Serbia has tremendous acreage and Mexico has had dramatically increasing acreage and will soon lead the world in hectarage and production.

The soft fruit is popular for use in desserts, jams, seedless jellies and sometimes wine. Since the many species form hybrids easily, there are numerous cultivars with more than one species in their ancestry.

Good nectar producers, blackberry shrubs bearing flowers yield a medium to dark, fruity honey.
Blackberry flower.

The blackberry is known to contain polyphenol antioxidants, naturally occurring chemicals that can upregulate certain beneficial metabolic processes in mammals. The astringent blackberry root is sometimes used in herbal medicine as a treatment for diarrhea and dysentery.The related but smaller dewberry can be distinguished by the white, waxy coating on the fruits, which also usually have fewer drupelets. (Rubus caesius) is in its own section (Caesii) within the subgenus Rubus.

In some parts of the world, such as in Australia, Chile, New Zealand and the Pacific Northwest region of North America, some blackberry species, particularly Rubus armeniacus (syn. R. procerus, 'Himalaya') and Rubus laciniatus ('Evergreen') are naturalised and considered an invasive species and a serious weed.

As there is forensic evidence from the Iron Age Haraldskær Woman that she consumed blackberries some 2500 years ago, it is reasonable to conclude that blackberries have been eaten by humans over thousands

Grapefruit


The grapefruit is a subtropical citrus tree known for its bitter fruit, an 18th-century hybrid first bred in Jamaica.When found in Barbados it was named the "forbidden fruit";it is also called the "shaddock", after its creator.

These evergreen trees are usually found at around 5–6 metres (16–20 ft) tall, although they can reach 13–15 metres (43–49 ft). The leaves are dark green, long (up to 150 mm, or 6 inches) and thin. It produces 5 cm (2 in) white four-petaled flowers. The fruit is yellow-orange skinned and largely oblate, and ranges in diameter from 10–15 cm. The flesh is segmented and acidic, varying in color depending on the cultivars, which include white, pink and red pulps of varying sweetness. The 1929 US Ruby Red (of the Redblush variety) has the first grapefruit patent.

The fruit has only become popular from the late 19th century; before that it was only grown as an ornamental plant. The US quickly became a major producer of the fruit, with orchards in Florida, Texas, Arizona, and California. In Spanish, the fruit is known as toronja or pomelo.

One ancestor was the Jamaican sweet orange (Citrus sinensis); the other was the Indonesian pomelo (Citrus maxima). Captain Shaddock brought pomelo seeds to Jamaica and bred the first fruit.

The hybrid fruit was in 1750 documented by the Rev. Griffith Hughes describing specimens from Barbados.Currently, the grapefruit is said to be one of the "Seven Wonders of Barbados."It was brought to Florida by Count Odette Philippe in 1823 in what is now known as Safety Harbor. Further crosses have produced the tangelo (1905), the minneola (1931), and the sweetie (1984). The sweetie has very small genetic and other differences from pomelo.

The grapefruit was known as the shaddock or shattuck until the 1800s. Its current name alludes to clusters of the fruit on the tree, which often appear similar to grapes.Botanically, it was not distinguished from the pomelo until the 1830s, when it was given the name Citrus paradisi. Its true origins were not determined until the 1940s. This led to the official name being altered to Citrus × paradisi.

The 1929 Ruby Red patent was associated with real commercial success, which came after the discovery of a red grapefruit growing on a pink variety. Only with the introduction of the Ruby Red did the grapefruit transform into a real agricultural success. The Red grapefruit, starting with the Ruby Red, has even become a symbolic fruit of Texas, where white "inferior" grapefruit were eliminated and only red grapefruit were grown for decades. Using radiation to trigger mutations, new varieties were developed to retain the red tones which typically faded to pink,the Rio Red variety is the current (2007) Texas grapefruit with registered trademarks Rio Star and Ruby-Sweet, also sometimes promoted as "Reddest" and "Texas Choice".

The Florida Department of Citrus stated "the primary varieties of Florida grapefruit are Ruby Red, Pink, Thompson, Marsh and Duncan. The fresh grapefruit season typically runs from October through June."

Grapefruit comes in many varieties, determinable by color, which is caused by the pigmentation of the fruit in respect of both its state of ripeness and genetic bent.The most popular varieties cultivated today are red, white, and pink hues, referring to the internal pulp color of the fruit. The family of flavors range from highly acidic and somewhat bitter to sweet and tart. Grapefruit mercaptan, a sulfur-containing terpene, is one of the substances which has a strong influence on the taste and odor of grapefruit, compared with other citrus fruits

Grapefruit can have a number of interactions with drugs, often increasing the effective potency of compounds. Grapefruit contains naringin, bergamottin and dihydroxybergamottin, which inhibit the protein isoform CYP3A4 predominately in the small intestine, but at higher doses, hepatic CYP3A4 inhibition is present as well.It is via inhibition of this enzyme that grapefruit increases the effects of a variety of drugs by increasing their bioavailability.The effect of grapefruit juice with regard to drug absorption was originally discovered in 1989. However, the effect became well-publicized after being responsible for a number of deaths due to overdosing on medication.

Grapefruit juice may be the first documented, but apple and orange juices have been also implicated in interfering with etoposide, a chemotherapy drug, some beta blocker drugs used to treat high blood pressure, and cyclosporine, taken by transplant patients to prevent rejection of their new organs.

Unlike other fruits grapefruit contains a large amount of naringin, and it can take up to 72 hours before the effects of the naringin on the CYP3A4 enzyme is seen. This is particularly problematic due to the fact that only 4 oz of grapefruit contain enough naringin to inhibit substrates of

Grapefruit is an excellent source of many nutrients and phytochemicals that contribute to a healthy diet. Grapefruit is a good source of vitamin C, pectin fiber, and the pink and red hues contain the beneficial antioxidant lycopene.Studies have shown grapefruit helps lower cholesterol and there is evidence that the seeds have high levels of antioxidant properties.Grapefruit forms a core part of the "grapefruit diet", the theory being that the fruit's low glycemic index is able to help the body's metabolism burn fat.

Grapefruit seed extract has been claimed to have strong antimicrobial properties, with proven activity against bacteria and fungi. However, no studies have demonstrated any efficacy by grapefruit seed extract as an antimicrobial for either bacteria or fungi. Additionally, although GSE is promoted as a highly effective plant-based preservative by some natural personal care manufacturers, studies have shown that the apparent antimicrobial activity associated with GSE preparations is merely due to contamination with synthetic preservatives.

A 2007 study found a correlation between eating a quarter of grapefruit daily and a 30% increase in risk for breast cancer in post-menopausal women. The study points to the inhibition of CYP3A4 enzyme by grapefruit, which metabolizes estrogen.However, there is a study showing that grapefruit consumption may not increase breast cancer risk. Furthermore, related studies showed a significant decrease in breast cancer risk with greater intake of grapefruit in women who never used hormone therapy.

Gooseberry


The gooseberry Ribes uva-crispa (syn. R. grossularia) is a species of Ribes, native to Europe, northwestern Africa and southwestern Asia. It is one of several similar species in the subgenus Grossularia; for the other related species (e.g., North American Gooseberry Ribes hirtellum), see the genus page Ribes.

Although usually placed as a subgenus within Ribes, a few taxonomists treat Grossularia as a separate genus, although hybrids between gooseberry and blackcurrant (e.g., the Jostaberry) are possible. The subgenus Grossularia differs somewhat from currants, chiefly in their spiny stems, and in that their flowers grow one to three together on short stems, not in racemes.

Gooseberry bushes produce an edible fruit and are grown on both a commercial and domestic basis

Growth habit and physical characteristics

The gooseberry is a straggling bush growing to 1-3 meters (3-10 feet) tall, the branches being thickly set with sharp spines, standing out singly or in diverging tufts of two or three from the bases of the short spurs or lateral leaf shoots. The bell-shaped flowers are produced, singly or in pairs, from the groups of rounded, deeply-crenated 3 or 5 lobed leaves. The fruit of wild gooseberries is smaller than in the cultivated varieties, but is often of good flavour; it is generally hairy, but in one variety smooth, constituting the R. uva-crispa of writers; berries' colour is usually green, but there are red variants and occasionally deep purple berries occur.

The gooseberry is indigenous in Europe and western Asia, growing naturally in alpine thickets and rocky woods in the lower country, from France eastward, well into the Himalayas and peninsular India.

In Britain, gooseberry bushes are often found in copses and hedgerows and about old ruins, but the gooseberry has been cultivated for so long that it is difficult to distinguish wild bushes from feral ones, or where the gooseberry fits into the native flora of the island. Common as it is now on some of the lower slopes of the Alps of Piedmont and Savoy, it is uncertain whether the Romans were acquainted with the gooseberry, though it may possibly be alluded to in a vague passage of Pliny the Elder's Natural History; the hot summers of Italy, in ancient times as at present, would be unfavourable to its cultivation. Although gooseberries are now abundant in Germany and France, it does not appear to have been much grown there in the Middle Ages, though the wild fruit was held in some esteem medicinally for the cooling properties of its acid juice in fevers; while the old English name, Fea-berry, still surviving in some provincial dialects, indicates that it was similarly valued in Britain, where it was planted in gardens at a comparatively early period.
William Turner describes the gooseberry in his Herball, written about the middle of the 16th century, and a few years later it is mentioned in one of Thomas Tusser's quaint rhymes as an ordinary object of garden culture. Improved varieties were probably first raised by the skilful gardeners of Holland, whose name for the fruit, Kruisbezie, may have been easily corrupted into the present English vernacular word. Towards the end of the 18th century the gooseberry became a favourite object of cottage-horticulture, especially in Lancashire, where the working cotton-spinners have raised numerous varieties from seed, their efforts having been chiefly directed to increasing the size of the fruit.

Of the many hundred varieties enumerated in recent horticultural works, few perhaps equal in flavour some of the older denizens of the fruit-garden, such as the old rough red and hairy amber. The climate of the British Isles seems peculiarly adapted to bring the gooseberry to perfection, and it may be grown successfully even in the most northern parts of Scotland where it is commonly known as a "grozet"; indeed, the flavour of the fruit is said to improve with increasing latitude. In Norway (where it’s named “stikkelsbær” — or “prickly berry”), the bush flourishes in gardens on the west coast nearly up to the Arctic circle, and it is found wild as far north as 63°. The dry summers of the French and German plains are less suited to it, though it is grown in some hilly districts with tolerable success. The gooseberry in the south of England will grow well in cool situations, and may be sometimes seen in gardens near London flourishing under the partial shade of apple trees; but in the north it needs full exposure to the sun to bring the fruit to perfection. It will succeed in almost any soil, but prefers a rich loam or black alluvium, and, though naturally a plant of rather dry places, will do well in moist land, if drained.

he easiest method of propagating gooseberries is by cuttings rather than raising from seed; cuttings planted in the autumn will take root quickly and can begin to bear fruit within a few years.

Vigorous pruning may be necessary; fruit is produced on lateral spurs and the previous year's shoots, so the 19th-century custom was to trim side branches in the winter, and perhaps trim leading shoots at that time or remove their tips in the summer.

Large berries can be produced by heavy composting, especially if the majority of the fruit is picked off while small to allow room for a few berries to continue to grow. Grafting of gooseberry vines onto ornamental golden currants (Ribes aurum) or other Ribes species can be helpful for this purpose. Some 19th- and early 20th-century cultivators produced single gooseberries near to two ounces in weight, but, as with many varieties of fruit, larger sizes of gooseberry proved to have weaker flavor.

Gooseberry bushes are vulnerable to magpie moth (Abraxas grossulariata) caterpillars. In cultivation, the best method for removing them is to remove the larvae by hand soon after they hatch; its eggs are laid on fallen gooseberry leaves.

Other potential threats are V-moth (Macaria wauaria) and Gooseberry sawfly (Nematus ribesii). Nematus reibesii grubs will bury themselves in the ground to pupate; on hatching into adult form, they lay their eggs, which soon hatch into larvae, on the underside of gooseberry leaves. 19th-century insecticides against these included tar water, weak solutions of carbolic acid, and powdered hellebore, which worked against magpie moths and V-moths as well as gooseberry sawflies. (Foxglove and tobacco infusions were also sometimes used.) Careful removal of fallen leaves and tilling of the ground around the plant will also destroy most eggs and chrysalises of these insects.

Potassium sulfide was known to be an effective treatment for blights and other parasitic growths, such as American gooseberry mildew.

Note that like most Ribes, the gooseberry is a potential host for white pine blister rust, which can cause serious damage to white pines; thus, gooseberry cultivation is illegal in some areas.

Gooseberries are best known for their use in desserts such as Gooseberry Fool and Gooseberry Crumble. In some countries, like Portugal, gooseberries are very appreciated as a beverage, being mostly used mixed with soda, water or even milk.

Plum


A plum or gage is a stone fruit tree in the genus Prunus, subgenus Prunus. The subgenus is distinguished from other subgenera (peaches, cherries, bird cherries, etc) in the shoots having a terminal bud and the side buds solitary (not clustered), the flowers being grouped 1-5 together on short stems, and the fruit having a groove running down one side, and a smooth stone.

Mature plum fruits may have a dusty-white coating that that gives them a glaucous appearance and is easily rubbed off. This is an epicuticular wax coating and is known as "wax bloom".

Cultivation and uses

Plum fruit tastes sweet and/or tart; the skin may be particularly tart. It is juicy and can be eaten fresh or used in jam-making or other recipes. Plum juice can be fermented into plum wine; when distilled, this produces a brandy known in Eastern Europe as Slivovitz, Rakia, Tzuica or Palinka. Dried plums are also known simply as prunes, as if 'prune' signified merely a dried plum - however, prunes are a distinct type of plum, and may have predated the fruits that we know more commonly as plums.[citation needed] Prunes are also sweet and juicy and contain several antioxidants. Plums and prunes are known for their laxative effect. This effect has been attributed to various compounds present in the fruits, such as dietary fiber, sorbitol,and isatin.Prunes and prune juice are often used to help regulate the functioning of the digestive system.

As with many other members of the rose family, plum seeds contain cyanogenetic glycosides, including amygdalin.These substances are capable of decomposing into a sugar molecule and hydrogen cyanide gas. While plum seeds are not the most toxic within the rose family, that dubious honor going to the bitter almond, large doses of these chemicals from any source are hazardous to human health.

Dried prune marketers in the United States have, in recent years, begun marketing their product as "dried plums." This is due to "prune" having negative connotations connected with elderly people suffering from constipation.

Dried, salted plums are used as a snack, sometimes known as salaito or salao. Various flavors of dried plum are available at Chinese grocers and specialty stores worldwide. They tend to be much drier than the standard prune. Cream, Ginsing, Spicy, and Salty are among the common varieties. Licorice is generally used to intensify the flavor of these plums and is used to make salty plum drinks and toppings for Shaved Ice or baobing.

Pickled plums are another type of preserve available in Asia and international specialty stores. The Japanese variety, called umeboshi, is often used for rice balls, called "Onigiri" or "Omusubi." The ume, from which umeboshi are made, is however more closely related to the apricot than to the plum.

Prune kernel oil is made from the fleshy inner part of the pit of the plum.

Plums come in a wide variety of colors and sizes. Some are much firmer-fleshed than others and some have yellow, white, green or red flesh, with equally varying skin color.
Blossoming plum, by Chinese artist Wang Mian (1287-1359).

Plum cultivars in use today include:

* Damson, or Damask Plum
* Greengage (Firm, green flesh and skin even when ripe.)
* Mirabelle (Dark yellow, predominantly grown in northeast France.)
* Satsuma plum (Firm red flesh with a red skin.)
* Yellowgage, or Golden plum (Similar to Greengage, but yellow.)

When it flowers in the early spring, a plum tree will be covered in blossom, and in a good year approximately 50% of the flowers will be pollinated and become plums. Flowering starts after 80 growing degree days.

If the weather is too dry the plums will not develop past a certain stage, but will fall from the tree while still tiny green buds, and if it is unseasonably wet or if the plums are not harvested as soon as they are ripe, the fruit may develop a fungal condition called brown rot. Brown rot is not toxic, and very small affected areas can be cut out of the fruit, but unless the rot is caught immediately the fruit will no longer be edible. Plum is used as a food plant by the larvae of some Lepidoptera including November Moth, Willow Beauty and Short-cloaked Moth.

The Serbian plum (Serbian: шљива / šljiva) is the third most produced in the world and the alcoholic drink slivovitz (Plum brandy) (Serbian: шљивовица / šljivovica) is the national drink of Serbia. The plum production averages 424,300 tons per year; FAO 1991–2001.[citation needed]

A large number of plums are also grown in Hungary where they are called szilva and are used to make lekvar (a plum paste jam), palinka (a slivovitz-type liquor), plum dumplings, and other foods. The region of Szabolcs-Szatmár, in the northeastern part of the country near the borders with Ukraine and Romania, is a major producer of plums.

The mei blossom (Prunus mume), along with the peony, are considered traditional floral emblems of China. On June 21, 1964, the Executive Yuan of the Republic of China officially designated the mei blossom to be its national flower, with the triple grouping of stamens (one long and two short) representing the Three Principles of the People and the five petals symbolizing the five branches of the ROC government.The designation repeats a previous statement by the ROC government in 1929.

The mei blossom is also the floral symbol of the ancient Chinese city Nanjing, which served as the former capital (and remained designated as the official capital) of the Republic of China.

Etymology

The fruit Prunus armeniaca gained its name from the beliefs of Pliny the Elder, a Roman historian and scientist of the 1st century, who maintained that the apricot was a kind of a plum, and had originally come from Armenia. Armenian sources support their claims by referring to a 6,000-year-old apricot pit found in an archaeological site near Yerevan.Other historians point that Mesopotamia as a clue to the Latin name. Apricots were cultivated in Mesopotamia, and it was known as armanu in the Akkadian language.

Top 10 Foods Highest in Beta Carotene...10


#10: Collards
A cousin of cabbage and also a good source of calcium, collards provide 3842μg of beta-carotene per 100g serving. Cooked collards provide even more with 4814μg per 100g serving.

The Cultivar Group name Acephala ("without a head" in Greek) refers to the fact that this variety of B. oleracea does not have the usual close-knit core of leaves ("head") like cabbage. The plant is a biennial where winter frost occurs, perennial in even colder regions. It is also moderately sensitive to salinity. It has an upright stalk, often growing up to 2 feet tall. The plant is very similar to kale. Popular cultivars of collard greens include Georgia Southern, Morris Heading, Butter Collard (or couve-manteiga), and couve tronchuda.

Nutrition:
Widely considered to be healthy foods, collards are good sources of vitamin C and soluble fiber and contain multiple nutrients with potent anti-cancer properties, such as diindolylmethane and sulforaphane.[citation needed] Roughly a quarter pound (approx. 100 g) of cooked collards contains 46 calories.

Researchers at the University of California at Berkeley have recently discovered that 3,3'-Diindolylmethane in Brassica vegetables such as collard greens is a potent modulator of the innate immune response system with potent anti-viral, anti-bacterial and anti-cancer activity.[citation needed]

#9: Lettuce
In regards to beta-carotene, the kind of lettuce does matter. Dark colorful lettuces provide the most beta-carotene with Red-Leaf Lettuce providing 4495μg per 100g, Green-Leaf providing 4443μg per 100g, and Iceberg only providing 299μg per 100g.

The lettuce plant has a short stem initially (a rosette growth habit), but when it gradually blooms, the stem and branches lengthens; and produces many flower heads that look like those of dandelions, but smaller. This is referred to as bolting. When grown to eat, lettuce is harvested before it bolts. Lettuce is used as a food plant by the larvae of some Lepidoptera.

#8: Butternut Squash
This dark orange squash has a delicious nutty and sweet flavor. 100 grams baked provides 4570μg of beta-carotene, 100 grams raw will provide 4226μg.

Butternut squash (Cucurbita moschata), also known in Australia as Butternut pumpkin[1], is a type of winter squash. It has a sweet, nutty taste that is similar to pumpkin. It has yellow skin and orange fleshy pulp. When ripe, it turns increasingly deep orange, and becomes sweeter and richer. It grows on a vine. The most popular variety, the Waltham Butternut, originated in Stow, Massachusetts, on what is now the Butternut Farm Golf Club
Butternut squash is a fruit that can be roasted and toasted and also be puréed or mashed into soups, casseroles, breads, and muffins.

In Australia it is regarded as a pumpkin, and used interchangeably with other types of pumpkin.

A common vegetable in South Africa, it is used in soup and can be cooked on a grill wrapped in foil with spices such as nutmeg and cinnamon.

It is a good source of fibre, vitamin C, manganese, magnesium, and potassium. It is also an excellent source of vitamin A

#7: Dried Herbs
Dried herbs are so packed with vitamins they appear on practically every HealthAliciousNess top 10 list. Make it a habit to add a pinch of dried herb to everything you prepare. Dried Basil provides the most beta-carotene with 5584μg per 100g serving, it is followed by Dried Parsley (5380μg), Marjoram (4806μg), Dried Oregano (4112μg), Ground Sage (3485μg), Dried Coriander (3407μg), and Fresh Thyme (2851μg).

#6: Spinach
An excellent vegetable to add to a wrap or calzone, raw spinach provides 5626μg of beta-carotene per 100g serving. Due to water loss during cooking, cooked spinach provides even more beta-carotene with 6288μg per 100g serving.

Nutrition:
Spinach has a high nutritional value and is extremely rich in antioxidants, especially when fresh, steamed, or quickly boiled. It is a rich source of vitamin A (and lutein), vitamin C, vitamin E, vitamin K, magnesium, manganese, folate, iron, vitamin B2, calcium, potassium, vitamin B6, folic acid, copper, protein, phosphorus, zinc, niacin, selenium and omega-3 fatty acids. Recently, opioid peptides called rubiscolins have also been found in spinach. It is a source of folic acid (Vitamin B9), and this vitamin was first purified from spinach. To benefit from the folate in spinach, it is better to steam it than to boil it. Boiling spinach for four minutes can halve the level of folate

#5: Mustard Greens
Mustard green have even more spice than turnip greens and are great in a salad or wrap. Mustard greens provide 6300μg of beta-carotene per 100g serving, cooked mustard greens will provide 3794μg.

Mustards are several plant species in the genera Brassica and Sinapis whose small mustard seeds are used as a spice and, by grinding and mixing them with water, vinegar or other liquids, are turned into the condiment known as mustard. The seeds are also pressed to make mustard oil, and the edible leaves can be eaten as mustard greens.

Mild white mustard (Sinapis hirta) grows wild in North Africa, the Middle East and Mediterranean Europe and has spread farther by long cultivation; brown or Indian mustard (B. juncea), originally from the foothills of the Himalaya, is grown commercially in the UK, Canada, Denmark and the US; black mustard (B. nigra) in Argentina, Chile, the US and some European countries. Canada grows 90% of all the mustard seed for the international market. The Canadian province of Saskatchewan produces almost half of the world's supply of mustard seed.

In addition to the mustards, the genus Brassica also includes cabbages, cauliflower, rapeseed, and turnips.

Although some varieties of mustard plants were well-established crops in Hellenistic and Roman times, Zohary and Hopf note that: "There are almost no archeological records available for any of these crops." Wild forms of mustard and its relatives the radish and turnip can be found over west Asia and Europe, suggesting that their domestication took place somewhere in that area. However, Zohary and Hopf conclude: "Suggestions as to the origins of these plants are necessarily based on linguistic considerations."

There has been recent research into varieties of mustards that have a high oil content for use in the production of biodiesel, a renewable liquid fuel similar to diesel fuel. The biodiesel made from mustard oil has good cold flow properties and cetane ratings. The leftover meal after pressing out the oil has also been found to be an effective pesticide.

An interesting genetic relationship between many species of mustard has been observed, and is described as the Triangle of U.

Nutrition

Leaf vegetables are typically low in calories, low in fat, high in protein per calorie, high in dietary fiber, high in iron and calcium, and very high in phytochemicals such as vitamin C, carotenoids, lutein and folic acid as well as Vitamin K.

Top 10 Foods Highest in Beta Carotene


#4: Turnip Greens
Turnip greens add a nice note of spice to any salad or soup. 100 grams of raw turnip greens provides 6952μg of beta-carotene, 100 grams cooked provides 4575μg.

The most common type of turnip is mostly white-skinned apart from the upper 1–6 centimeters, which protrude above the ground and are purple, red, or greenish wherever sunlight has fallen. This above-ground part develops from stem tissue, but is fused with the root. The interior flesh is entirely white. The entire root is roughly conical, but can be occasionally tomato-shaped, about 5–20 centimeters in diameter, and lacks side roots. The taproot (the normal root below the swollen storage root) is thin and 10 centimeters or more in length; it is trimmed off before marketing. The leaves grow directly from the above-ground shoulder of the root, with little or no visible crown or neck (as found in rutabagas).

Turnip leaves are sometimes eaten as "turnip greens" ("turnip tops" in the UK), and they resemble mustard greens in flavor. Turnip greens are a common side dish in southeastern US cooking, primarily during late fall and winter. Smaller leaves are preferred; however, any bitter taste of larger leaves can be reduced by pouring off the water from initial boiling and replacing it with fresh water. Varieties specifically grown for the leaves resemble mustard greens more than those grown for the roots, with small or no storage roots. Varieties of B. rapa that have been developed only for use as leaves are called Chinese cabbage. Both leaves and root have a pungent flavor similar to raw cabbage or radishes that becomes mild after cooking.

Turnip roots weigh up to about 1 kilogram, although they can be harvested when smaller. Size is partly a function of variety and partly a function of the length of time that the turnip has grown. Most very small turnips (also called baby turnips) are specialty varieties. These are only available when freshly harvested and do not keep well. Most baby turnips can be eaten whole, including their leaves. Baby turnips come in yellow-, orange-, and red-fleshed varieties as well as white-fleshed. Their flavor is mild, so they can be eaten raw in salads like radishes.

Nutrition:
The turnip's root is high only in Vitamin C. The green leaves of the turnip top ("turnip greens") are a good source of Vitamin A, folate, Vitamin C, Vitamin K and calcium. Turnip greens are high in lutein (8.4 mg / 100g).

#3: Carrots
The beta-carotene in carrots gives them their orange color. 100 grams of raw carrots provides 8285μg of beta-carotene, one medium sized carrot(61g) will provide 5053μg, and one baby carrot(10g) will provide 639μg.

The carrot (Daucus carota subsp. sativus, Etymology: Middle French carotte, from Late Latin carōta, from Greek karōton, originally from the Indo-European root ker- (horn), due to its horn-like shape) is a root vegetable, usually orange, purple, red, white, or yellow in colour, with a crisp texture when fresh. The edible part of a carrot is a taproot. It is a domesticated form of the wild carrot Daucus carota, native to Europe and southwestern Asia. It has been bred for its greatly enlarged and more palatable, less woody-textured edible taproot, but is still the same species.

It is a biennial plant which grows a rosette of leaves in the spring and summer, while building up the stout taproot, which stores large amounts of sugars for the plant to flower in the second year. The flowering stem grows to about 1 metre (3 ft) tall, with an umbel of white flowers that produce a fruit called a mericarp by botanists, which is a type of schizocarp

Use and nutrition
Carrots can be eaten in a variety of ways. The simplest way is raw as carrots are perfectly digestible without requiring cooking. Alternatively they may be chopped and boiled, fried or steamed, and cooked in soups and stews, as well as baby and pet foods. A well known dish is carrots julienne. Grated carrots are used in carrot cakes, as well as carrot puddings, an old English dish thought to have originated in the early 1800s. The greens are edible as a leaf vegetable, but are rarely eaten by humans, as they are mildly toxiTogether with onion and celery, carrots are one of the primary vegetables used in a mirepoix to make various broths.
Carrot flowers

Ever since the late 1980s, baby carrots or mini-carrots (carrots that have been peeled and cut into uniform cylinders) have been a popular ready-to-eat snack food available in many supermarkets.

Carrot juice is also widely marketed, especially as a health drink, either stand-alone or blended with fruits and other vegetables.

The carrot gets its characteristic and bright orange colour from β-carotene, which is metabolised into vitamin A in humans when bile salts are present in the intestines.[3] Massive overconsumption of carrots can cause carotenosis, a benign condition in which the skin turns orange. Carrots are also rich in dietary fibre, antioxidants, and minerals.

Lack of Vitamin A can cause poor vision, including night vision, and vision can be restored by adding Vitamin A back into the diet. An urban legend says eating large amounts of carrots will allow one to see in the dark. The legend developed from stories of British gunners in World War II who were able to shoot down German planes in the darkness of night. The legend arose during the Battle of Britain when the RAF circulated a story about their pilots' carrot consumption as an attempt to cover up the discovery and effective use of radar technologies in engaging enemy planes, as well as the use of red light (which does not destroy night vision) in aircraft instruments.[4][5] It reinforced existing German folklore and helped to encourage Britons—looking to improve their night vision during the blackouts—to grow and eat the vegetable.

Ethnomedically, the roots are used to treat digestive problems, intestinal parasites, and tonsillitis or constipation.

#2: Kale
Kale is considered to be an early form of cabbage, and is delicious steamed with wine. 100 grams of raw kale will provide 9226μg of beta-carotene, 100 grams cooked will provide 8173μg.

Kale or borecole is a form of cabbage (Brassica oleracea Acephala Group), green or purple, in which the central leaves do not form a head. It is considered to be closer to wild cabbage than most domesticated forms. The species Brassica oleracea contains a wide array of vegetables including broccoli, cauliflower, collard greens, and brussels sprouts. The Cultivar Group Acephala also includes spring greens and collard greens, which are extremely similar genetically.

Nutritional value
Kale is considered to be a highly nutritious vegetable with powerful antioxidant properties and is anti-inflammatory.[2]

Kale is very high in beta carotene, vitamin K, vitamin C, lutein, zeaxanthin, and reasonably rich in calcium. Because of its high vitamin K content, patients taking anti-coagulants such as warfarin are encouraged to avoid this food since it increases the vitamin K concentration in the blood, which is what the drugs are often attempting to lower.

Kale, as with broccoli and other brassicas, contains sulforaphane (particularly when chopped or minced), a chemical believed to have potent anti-cancer properties

1: Sweet Potato
Perhaps the most orange of all fruits and vegetables, sweet potatoes will provide 9444μg of beta carotene per 100g serving. That is 14260μg in a medium sized potato(150g).

Nutrition and health benefits

Besides simple starches, sweet potatoes are rich in complex carbohydrates, dietary fiber, beta carotene (a vitamin A equivalent nutrient), vitamin C, and vitamin B6. Pink and yellow varieties are high in carotene, the precursor of vitamin A.

In 1992, the Center for Science in the Public Interest compared the nutritional value of sweet potatoes to other vegetables. Considering fibre content, complex carbohydrates, protein, vitamins A and C, iron, and calcium, the sweet potato ranked highest in nutritional value. According to these criteria, sweet potatoes earned 184 points, 100 points over the next on the list, the common potato.(NCSPC)

Sweet potato varieties with dark orange flesh have more beta carotene than those with light coloured flesh, and their increased cultivation is being encouraged in Africa, where vitamin A deficiency is a serious health problem. Despite the name "sweet", it may be a beneficial food for diabetics, as preliminary studies on animals have revealed that it helps to stabilize blood sugar levels and to lower insulin resistance.[13] Some Americans, including television personality Oprah Winfrey, are advocating increased consumption of sweet potatoes both for their health benefits and because of their importance in traditional Southern cuisine.

A 100g root is reported to contain 108-121 calories, 68.5-72.3 g water, 1-1.7 g protein, 0.2-0.4 g fat, 25-31.0 total carbohydrate, 0.7-1.0 g ash, 21–36 mg Ca, 38–56 mg P, 0.7-2.0 mg Fe, 10–36 mg Na, 210–304 mg K, 35-5,280 µg beta-carotene equivalent, 0.09-0.14 mg thiamine, 0.04-0.06 mg riboflavin, 0.6-0.7 mg niacin, and 21–37 mg ascorbic acid.

The peptic substance (0.78 percent total, 0.43 percent soluble) present in fresh tubers contains uronic acid (60 percent) and methoxyl (4 to 5 percent). Other constituents include phytin (1.05 percent), two monoaminophosphatides (probably lecithin and cephalin), organic acids (oxalic acid), phytosterolin, phytosterol, resins, tannins, and colouring matter. Sweet potato contanins calcium, 30; magnesium, 24; potassium, 373; sodium, 13; phosphorus, 49; chlorine, 85; sulphur, 26; iron, 0.8 mg/100g; iodine, 4.5 µg/kg; manganese, copper and zinc are present in traces (Hug et al., 1983).

Pineapple


Pineapple (Ananas comosus) is the common name for an edible tropical plant and also its fruit.[1] It is native to Paraguay and the southern part of Brazil.Pineapple is eaten fresh or canned and is available as a juice or in juice combinations. It is used in desserts, salads, as a complement to meat dishes and in fruit cocktail. While sweet, it is known for its high acid content (perhaps malic and/or citric). Pineapples are the only bromeliad fruit in widespread cultivation. It is one of the most commercially important plants which carry out CAM photosynthesis.

Etymology
he word pineapple in English was first recorded in 1398, when it was originally used to describe the reproductive organs of conifer trees (now termed pine cones). When European explorers discovered this tropical fruit, they called them pineapples (term first recorded in that sense in 1664) because of their resemblance to what is now known as the pine cone. The term pine cone was first recorded in 1694 and was used to replace the original meaning of pineapple.

In the scientific binomial Ananas comosus, ananas, the original name of the fruit, comes from the Tupi (Rio de Janeiro, Brazil) word for pine nanas, as recorded by André Thevenet in 1555 and comosus means "tufted" and refers to the stem of the fruit. Other members of the Ananas genus are often called pine as well by laymen.

Many languages use the Tupian term ananas. In Spanish, pineapples are called piña "pine cone" in Spain and most Hispanic American countries, or ananá (ananás in Argentina) (see the piña colada drink). They have varying names in the languages of India: "Anaasa" (అనాస) in telugu, annachi pazham (Tamil), anarosh (Bengali), and in Malayalam, kaitha chakka. In Malay, pineapples are known as "nanas" or "nenas". In the Maldivian language of Dhivehi, pineapples are known as alanaasi. A large, sweet pineapple grown especially in Brazil is called abacaxi [abakaˈʃiː].

Botany
The pineapple is a herbaceous perennial plant which grows to 1.0 to 1.5 metres (3.3 to 4.9 ft) tall with 30 or more trough-shaped and pointed leaves 30 to 100 centimetres (1.0 to 3.3 ft) long, surrounding a thick stem. The pineapple is an example of a multiple fruit: multiple, helically-arranged flowers along the axis each produce a fleshy fruit that becomes pressed against the fruits of adjacent flowers, forming what appears to be a single fleshy fruit.

The fruit of a pineapple are arranged in two interlocking helices, eight in one direction, thirteen in the other, each being a Fibonacci number.

The leaves of the cultivar 'Smooth Cayenne' mostly lack spines except at the leaf tip, but the cultivars 'Spanish' and 'Queen' have large spines along the leaf margins.

Pollination
The natural (or most common) pollinator of the pineapple is the hummingbird.[citation needed] Pollination is required for seed formation; the presence of seeds negatively affects the quality of the fruit. In Hawaii, where pineapple is cultivated on an agricultural scale, importation of hummingbirds is prohibited for this reason.

Certain bat-pollinated wild pineapples, members of the bromeliad family, do the exact opposite of most flowers by opening their flowers at night and closing them during the day.

Nutrition
Pineapple contains a proteolytic enzyme bromelain, which breaks down protein. Pineapple juice can thus be used as a marinade and tenderizer for meat. The enzymes in raw pineapples can interfere with the preparation of some foods, such as jelly or other gelatin-based desserts. The bromelain breaks down in cooking or the canning process, thus canned pineapple can generally be used with gelatin. These enzymes can be hazardous to someone suffering from certain protein deficiencies or disorders, such as Ehlers-Danlos syndrome.[citation needed] Raw pineapples also should not be consumed by those with hemophilia or by those with kidney or liver disease, as it may reduce the time taken to coagulate a consumer's blood.[citation needed]

Consumers of pineapple have claimed that pineapple has benefits for some intestinal disorders and others believe it serves as a pain reliever; others claim that it helps to induce childbirth when a baby is overdue.

Pineapple is a good source of manganese (91 %DV in a 1 cup serving), as well as containing significant amounts of Vitamin C (94 %DV in a 1 cup serving) and Vitamin B1 (8 %DV in a 1 cup serving)

The natives of southern Brazil and Paraguay spread the pineapple throughout South America, and it eventually reached the Caribbean. Columbus discovered it in the Indies and brought it back with him to Europe.The Spanish introduced it into the Philippines, Hawaii (introduced in the early 19th century, first commercial plantation 1886), Zimbabwe and Guam. The fruit was cultivated successfully in European hothouses, and pineapple pits, beginning in 1720. Commonly grown cultivars include 'Red Spanish', 'Hilo', 'Smooth Cayenne', 'St. Michael', 'Kona Sugarloaf', 'Natal Queen', and 'Pernambuco'.

History
The pineapple was introduced to Hawaii in 1813; exports of canned pineapples began in 1892. Large scale pineapple cultivation by U.S. companies began in the early 1900s on Hawaii. Among the most famous and influential pineapple industrialists was James Dole, who started a pineapple plantation in Hawaii in the year 1900.The companies Dole and Del Monte began growing pineapple on the island of Oahu in 1901 and 1917, respectively. Maui Pineapple Company began pineapple cultivation on the island of Maui in 1909. In 2006, Del Monte announced its withdrawal from pineapple cultivation in Hawaii, leaving only Dole and Maui Pineapple Company in Hawaii as the USA’s largest growers of pineapples. Maui Pineapple Company markets its Maui Gold brand of pineapple and Dole markets its Hawaii Gold brand of pineapple.

In the USA in 1986, the Pineapple Research Institute was dissolved and its assets were divided between Del Monte and Maui Land and Pineapple. Del Monte took 73-114, which it dubbed MD-2, to its plantations in Costa Rica, found it to be well-suited to growing there, and launched it publicly in 1996. (Del Monte also began marketing 73-50, dubbed CO-2, as Del Monte Gold). In 1997, Del Monte began marketing its Gold Extra Sweet pineapple, known internally as MD-2. MD-2 is a hybrid that originated in the breeding program of the now-defunct Pineapple Research Institute in Hawaii, which conducted research on behalf of Del Monte, Maui Land & Pineapple Company, and Dole.

Cultivation
Southeast Asia dominates world production: in 2001 Thailand produced 1.979 million tons, the Philippines 1.618 million tons while in the Americas, Brazil 1.43 million tons. Total world production in 2001 was 14.220 million tons. The primary exporters of fresh pineapples in 2001 were Costa Rica, 322,000 tons; Côte d'Ivoire, 188,000 tons; and the Philippines, 135,000 tons.
An unripe pineapple fruit

At one time, most canned and fresh pineapples came from the cultivar 'Smooth Cayenne'. Since about 2000, the most common fresh pineapple fruit found in U.S. and European supermarkets is a low-acid hybrid that was developed in Hawaii in the early 1970s.

In commercial farming, flowering can be induced artificially, and the early harvesting of the main fruit can encourage the development of a second crop of smaller fruits. Once removed during cleaning, the top of the pineapple can be planted in soil and a new fruit-bearing plant will grow in a manner similar to that of a potato or onion, which will sprout from a cutting. Crowns are the primary method of propagation for home gardeners, though slips and suckers are preferred

Cultivars
# Hilo': A compact 1–1.5 kg (2-3 lb) Hawaiian variant of 'Smooth Cayenne'. The fruit is more cylindrical and produces many suckers but no slips.
# 'Kona Sugarloaf': 2.5–3 kg (5-6 lb), white flesh with no woodiness in the center. Cylindrical in shape, it has a high sugar content but no acid. An unusually sweet fruit.
# 'Natal Queen': 1–1.5 kg (2-3 lb), golden yellow flesh, crisp texture and delicate mild flavor. Well adapted to fresh consumption. Keeps well after ripening. Leaves spiny.
# 'Pernambuco' ('Eleuthera'): 1–2 kg (2-4 lb) with pale yellow to white flesh. Sweet, melting and excellent for eating fresh. Poorly adapted for shipping. Leaves spiny.
# 'Red Spanish': 1–2 kg (2-4 lb), pale yellow flesh with pleasant aroma; squarish in shape. Well adapted for shipping as fresh fruit to distant markets. Leaves spiny.
# 'Smooth Cayenne': 2.5–3 kg (5-6 lb), pale yellow to yellow flesh. Cylindrical in shape and with high sugar and acid content. Well adapted to canning and processing. Leaves without spines. This is the variety from Hawaii, and the most easily obtainable in U.S. grocery stores. Both 73-114 and 73-50 are of this cultivar.

Ethno-medical usage
The root and fruit are either eaten or applied topically as an anti-inflammatory and as a proteolytic agent. It is traditionally used as an antihelminthic agent in the Philippines

Pests and diseases

Pineapples are subject to a variety of diseases,the most serious of which is wilt disease vectored by mealybugs.The mealybugs are generally found on the surface of pineapples, but can also be found inside the closed blossom cups.Other diseases include pink disease,bacterial heart rot, and anthracnose.

Storage and transport

Fresh pineapple is often somewhat expensive as the tropical fruit is delicate and difficult to ship. Pineapples can ripen after harvest, but require certain temperatures for this process to occur.[citation needed] Like bananas, they are chill-sensitive and should not be stored in the refrigerator. They will, however, ripen if left outside of a refrigerator.The ripening of pineapples can be rather difficult as they will not ripen for some time and in a day or two become over-ripe, therefore, pineapples are most widely available canned.

Usage in culture

* In some cultures, the pineapple has become associated with the notion of welcome,an association bespoken by the use of pineapple motifs as carved decorations in woodworking.
* In the Philippines, pineapple leaves are used as the source of a textile fiber called piña.

Sapindaceae


Sapindaceae, also known as the soapberry family, is a family of flowering plants in the order Sapindales. There are about 140-150 genera with 1400-2000 species, including maple, horse chestnut and lychee.

Sapindaceae members occur in temperate to tropical regions throughout the world. Many are lactiferous, i.e. they contain milky sap, and many contain mildly toxic saponins with soap-like qualities in either the foliage and/or the seeds, or roots. The largest genera are Serjania, Paullinia, Acer and Allophyllus.

The largely temperate genera formerly separated in the families Aceraceae (Acer, Dipteronia) and Hippocastanaceae (Aesculus, Billia, Handeliodendron) were included within a more broadly circumscribed Sapindaceae by the APG. Recent research has confirmed the inclusion of these genera in Sapindaceae

Characteristics
Plants of this family have a variety of habits, from trees to herbaceous plants or lianas. Their leaves usually spirally alternate, sometimes (in Acer, Aesculus, and a few other genera) opposite. They are most often pinnately compound, sometimes palmately, or just palmate (Acer, Aesculus), with a petiole lacking stipules, but having a swollen base.
Dodonaea viscosa flowers

Flowers are small and unisexual, or functionally unisexual, though plants may be either dioecious or monoecious. They are usually grouped in cymes grouped in panicles. They most often have four or five petals and sepals (petals are absent in Dodonaea). The stamens range from four to ten, usually on a nectar disc between the petals and stamen,their filaments are often hairy. The most frequent number is eight, in two rings of four. The gynoecium contains two or three carpels, sometimes up to six. There is usually only one style with a lobed stigma. Most often pollinated by birds or insects, with a few species pollinated by wind.

The fruits are fleshy or dry. They may be nuts, berries, drupes, schizocarps, capsules (Bridgesia), or samaras (Acer). The embryos are bent or coiled, without endosperm in the seed, but frequently with an aril.

Sapindaceae are related to Rutaceae, and both are usually placed in an order Sapindales or Rutales, depending on whether they are kept separate and which name is used for the order.The most basal member appears to be Xanthoceras. Some authors maintain some or all of Hippocastanaceae and Aceraceae, although this may result in paraphyly.The former Ptaeroxylaceae, now placed in Rutaceae, were sometimes placed in Sapindaceae.The family is divided in 5 or 6 subfamily depending on treatment.

Notable species
Sapindaceae includes many species of economically valuable tropical fruit, including the lychee, longan, pitomba, korlan, rambutan, mamoncillo and ackee. Other products include Guarana, soapberries and maple syrup.

Some species of Maple and Buckeye are valued for their wood, while several other genera, such as Koelreuteria, Cardiospermum and Ungnadia, are popular ornamentals. Schleichera trijuga is the source of Indian macassar oil. Saponins extracted from the drupe of Sapindus species are effective surfactants and are used commercially in cosmetics and detergents.

Orange (fruit)


An orange—specifically, the sweet orange—is the citrus Citrus ×sinensis (syn. Citrus aurantium L. var. dulcis L., or Citrus aurantium Risso) and its fruit. The orange is a hybrid of ancient cultivated origin, possibly between pomelo (Citrus maxima) and tangerine (Citrus reticulata). It is a small flowering tree growing to about 10 m tall with evergreen leaves, which are arranged alternately, of ovate shape with crenulate margins and 4–10 cm long. The orange fruit is a hesperidium, a type of berry.

Oranges originated in Southeast Asia. The fruit of Citrus sinensis is called sweet orange to distinguish it from Citrus aurantium, the bitter orange. The name is thought to ultimately derive from the Sanskrit for the orange tree, with its final form developing after passing through numerous intermediate languages.

In a number of languages, it is known as a "Chinese apple" (e.g. Dutch Sinaasappel, "China's apple").

All citrus trees are of the single genus, Citrus, and remain largely interbreedable; that is, there is only one "superspecies" which includes grapefruits, lemons, limes, and oranges. Nevertheless, names have been given to the various members of the genus, oranges often being referred to as Citrus sinensis and Citrus aurantium. Fruits of all members of the genus Citrus are considered berries because they have many seeds, are fleshy and soft, and derive from a single ovary. An orange seed is called a pip. The white thread-like material attached to the inside of the peel is called pith.

Blood orange
he blood orange has streaks of red in the fruit, and the juice is often a dark burgundy colour. The fruit has found a niche as an interesting ingredient variation on traditional Seville marmalade, with its striking red streaks and distinct flavour. The scarlet navel is a variety with the same dual-fruit mutation as the navel orange

A single mutation in 1820 in an orchard of sweet oranges planted at a monastery in Brazil yielded the navel orange, also known as the Washington, Riverside, or Bahie navel. The mutation causes the orange to develop a second orange at the base of the original fruit, opposite the stem, as a conjoined twin in a set of smaller segments embedded within the peel of the larger orange. From the outside, it looks similar to the human navel, thus its name.

Because the mutation left the fruit seedless, and therefore sterile, the only means available to cultivate more of this new variety is to graft cuttings onto other varieties of citrus tree. Two such cuttings of the original tree were transplanted to Riverside, California in 1870, which eventually led to worldwide popularity.

Today, navel oranges continue to be produced via cutting and grafting. This does not allow for the usual selective breeding methodologies, and so not only do the navel oranges of today have exactly the same genetic makeup as the original tree, and are therefore clones, in a sense, all navel oranges can be considered to be the fruit of that single over-a-century-old tree. This is similar to the common yellow seedless banana, the Cavendish. On rare occasions, however, further mutations can lead to new varieties.

Persian orange

The Persian orange, grown widely in southern Europe after its introduction to Italy in the 11th century, was bitter. Sweet oranges brought to Europe in the 15th century from India by Portuguese traders quickly displaced the bitter, and are now the most common variety of orange cultivated. The sweet orange will grow to different sizes and colours according to local conditions, most commonly with ten carpels, or segments, inside.

Some South East Indo-European tongues name orange after Portugal, which was formerly the main source of imports of sweet oranges. Examples are Bulgarian portokal [портокал], Greek portokali [πορτοκάλι], Persian porteqal [پرتقال], Albanian "portokall", Macedonian portokal [портокал], and Romanian portocală. Also in South Italian dialects (Neapolitan), orange is named portogallo or purtualle, literally "the Portuguese one". Related names can also be found in other languages: Turkish Portakal, Arabic al-burtuqal [البرتقال], Amharic birtukan, and Georgian phortokhali [ფორთოხალი].

Portuguese, Spanish, Arab, and Dutch sailors planted citrus trees along trade routes to prevent scurvy. On his second voyage in 1493, Christopher Columbus brought the seeds of oranges, lemons and citrons to Haiti and the Caribbean. They were introduced in Florida (along with lemons) in 1513 by Spanish explorer Juan Ponce de León, and were introduced to Hawaii in 1792.

Valencia orange
The Valencia or Murcia orange is one of the sweet oranges used for juice extraction. It is a late-season fruit, and therefore a popular variety when the navel oranges are out of season. For this reason, the orange was chosen to be the official mascot of the 1982 FIFA World Cup, which was held in Spain. The mascot was called "Naranjito" ("little orange"), and wore the colours of the Spanish football team uniform.
