The pear is an edible pomaceous fruit produced by a tree of genus Pyrus (pronounced /ˈpaɪrəs/).The pear is classified within Maloideae, a subfamily within Rosaceae. The apple (Malus ×domestica), which it resembles in floral structure, is also a member of this subfamily.

The English word pear is probably from Common West Germanic *pera, probably a loanword of Vulgar Latin pira, the plural of pirum, akin to Greek api(r)os, which is likely of Semitic origin. The place name Perry can indicate the historical presence of pear trees. The term “pyriform” is sometimes used to describe something which is “pear-shaped”.

History

The cultivation of the pear in cool temperate climates extends to the remotest antiquity. Many traces of it have been found in the Swiss lake-dwellings. The word “pear” or its equivalent occurs in all the Celtic languages, while in Slavonic and other dialects different appellations, but still referring to the same thing, are found—a diversity and multiplicity of nomenclature which led Alphonse de Candolle to infer a very ancient cultivation of the tree from the shores of the Caspian to those of the Atlantic.

Pears grow in the sublime orchard of Alcinous, in Odyssey vii: “Therein grow trees, tall and luxuriant, pears and pomegranates and apple-trees with their bright fruit, and sweet figs, and luxuriant olives. Of these the fruit perishes not nor fails in winter or in summer, but lasts throughout the year.”

The pear was cultivated also by the Romans, who did not eat them raw: Pliny’s Natural History recommended stewing them with honey and noted three dozen varieties. The Roman cookbook attributed to Apicius, De re coquinaria, has a recipe for a spiced stewed-pear patina, or soufflé.

A certain race of pears, with white down on the under surface of their leaves, is supposed to have originated from P. nivalis, and their fruit is chiefly used in France in the manufacture of perry (see also cider). Other small-fruited pears, distinguished by their early ripening and apple-like fruit, may be referred to P. cordata, a species found wild in western France, and in Devonshire and Cornwall. Pears have been cultivated in China for approximately 3000 years. The genus is thought to have originated in present-day western China in the foothills of the Tian Shan, a mountain range of Central Asia, and to have spread to the north and south along mountain chains, evolving into a diverse group of over 20 widely recognized primary species. The enormous number of varieties of the cultivated European pear (Pyrus communis subsp. communis), are without doubt derived from one or two wild subspecies (P. communis subsp. pyraster and P. communis subsp. caucasica), widely distributed throughout Europe, and sometimes forming part of the natural vegetation of the forests. In England, where an ancient pear tree gave its name to[citation needed] Pirio (Perry Barr, a district of Birmingham) in Domesday, the pear is sometimes considered wild; there is always the doubt that it may not really be so, but the produce of some seed of a cultivated tree deposited by birds or otherwise, which has germinated as a wild-form spine-bearing tree. Court accounts of Henry III of England record pears shipped from Rochelle and presented to the King by the Sheriffs of London. The French names of pears grown in English medieval gardens suggests that their reputation, at the least, was French; a favored variety in the accounts was named for Saint Rule or Regul’, bishop of Senlis.

Asian species with medium to large edible fruit include P. pyrifolia, P. ussuriensis, P. ×bretschneideri, P. ×sinkiangensis, and P. pashia. Other small-fruited species are frequently used as rootstocks for the cultivated species.

Botany

Pears are native to coastal and mildly temperate regions of the Old World, from western Europe and north Africa east right across Asia. They are medium sized trees, reaching 10–17 m tall, often with a tall, narrow crown; a few species are shrubby. The leaves are alternately arranged, simple, 2–12 cm long, glossy green on some species, densely silvery-hairy in some others; leaf shape varies from broad oval to narrow lanceolate. Most pears are deciduous, but one or two species in southeast Asia are evergreen. Most are cold-hardy, withstanding temperatures between −25 °C and −40 °C in winter, except for the evergreen species, which only tolerate temperatures down to about −15 °C. The flowers are white, rarely tinted yellow or pink, 2–4 cm diameter, and have five petals. Like that of the related apple, the pear fruit is a pome, in most wild species 1–4 cm diameter, but in some cultivated forms up to 18 cm long and 8 cm broad; the shape varies in most species from oblate or globose, to the classic pyriform ‘pear-shape’ of the European Pear with an elongated basal portion and a bulbous end.

The fruit is composed of the receptacle or upper end of the flower-stalk (the so-called calyx tube) greatly dilated. Enclosed within its cellular flesh is the true fruit: five cartilaginous carpels, known colloquially as the “core”. From the upper rim of the receptacle are given off the five sepals, the five petals, and the very numerous stamens.

The pear is very similar to the apple in cultivation, propagation and pollination.

Pears and apples cannot always be distinguished by the form of the fruit; some pears look very much like some apples. One major difference is that pears have “grit” – clusters of lignified cells. Pear trees and apple trees do have several visible differences. The pear and the apple are also related to the quince.

There are about 30 primary species, major subspecies, and naturally occurring interspecific hybrids of pears.

Cultivation

The pear may be readily raised by sowing the pips of ordinary cultivated or of wilding kinds, these forming what are known as free or pear stocks, on which the choicer varieties are grafted for increase. For new varieties the flowers can be cross-bred to preserve or combine desirable traits. The fruit of the pear is produced on spurs, which appear on shoots more than one year old.

Three species account for the vast majority of edible fruit production, the European Pear Pyrus communis subsp. communis cultivated mainly in Europe and North America, the Chinese white pear (bai li) Pyrus ×bretschneideri, and the Nashi Pear Pyrus pyrifolia (also known as Asian Pear or Apple Pear), both grown mainly in eastern Asia. There are thousands of cultivars of these three species. A species grown in western China, P. sinkiangensis, and P. pashia, grown in southern China and south Asia, are also produced to a lesser degree.

Other species are used as rootstocks for European and Asian pears and as ornamental trees. The Siberian Pear, Pyrus ussuriensis (which produces unpalatable fruit) has been crossed with Pyrus communis to breed hardier pear cultivars. The Bradford Pear (Pyrus calleryana ‘Bradford’) in particular has become widespread in North America and is used only as an ornamental tree. The Willow-leafed Pear (Pyrus salicifolia) is grown for its attractive slender, densely silvery-hairy leaves.

Harvest

Summer and autumn pears are gathered before they are fully ripe, while they are still green, but snap off when lifted. If left to ripen and turn yellow on the tree, the sugars will turn to starch crystals and the pear will have a gritty texture inside. In the case of the ‘Passe Crassane’, long the favored winter pear in France, the crop should be gathered at three different times, the first a fortnight or more before it is ripe, the second a week or ten days after that, and the third when fully ripe. The first gathering will come into eating latest, and thus the season of the fruit may be considerably prolonged.

Uses

Pears are consumed fresh, canned, as juice, and dried. The juice can also be used in jellies and jams, usually in combination with other fruits or berries. Fermented pear juice is called perry.

Pears will ripen faster if placed next to bananas in a fruit bowl. They stay fresh for longer if kept in a fridge.

Pear wood is one of the preferred materials in the manufacture of high-quality woodwind instruments and furniture. It is also used for wood carving, and as a firewood to produce aromatic smoke for smoking meat or tobacco.

Health Benefits

Pears are rich in Vitamin A, Vitamin C, E1, copper and potassium. Pears are the least allergenic of all fruits. Because of this, it is sometimes used as the first juice introduced to infants. Along with lamb and soya formula, pears form part of the strictest exclusion diet for allergy sufferers.

Pears can be useful in treating inflammation of mucous membranes, colitis, chronic gallbladder disorders, arthritis, and gout. Pears can also be beneficial in lowering high blood pressure, controlling blood cholesterol levels, and increasing urine acidity. They are good for the lungs and the stomach.

Most of the fiber is insoluble, making pears a good laxative. The gritty fiber content may cut down on the number of cancerous colon polyps. Most of the vitamin C, as well as the dietary fibre, are contained within the skin of the fruit.

Recipes:

As you know it is a very unique Fruit, so it will not have many recipes but Few of them are here:

Spinach (Spinacia oleracea) is an edible flowering plant in the family of Amaranthaceae. It is native to central and southwestern Asia. It is an annual plant (rarely biennial), which grows to a height of up to 30 cm. Spinach may survive over winter in temperate regions. The leaves are alternate, simple, ovate to triangular-based, very variable in size from about 2-30 cm long and 1-15 cm broad, with larger leaves at the base of the plant and small leaves higher on the flowering stem. The flowers are inconspicuous, yellow-green, 3-4 mm diameter, maturing into a small hard dry lumpy fruit cluster 5-10 mm across containing several seeds.

History

Primitive forms of spinach are found in Nepal and that is probably where the plant was first domesticated. Other than the Indian subcontinent, it was unknown in the ancient world. After the early Muslim conquests the plant spread to other areas. In 647, it was taken to China, possibly by Persians. Muslim Arabs diffused the plant westward up to Islamic Spain. By the eleventh century it was a common plant in the Muslim world.

In India, in Malayalam, it is called Cheera (ചീര), in Tamil, it is called Keerai and in Marathi it is known as Palak .Paala koora in Telugu and is one among commonly consumed green vegetables.

Spinach was the favorite vegetable of Catherine de Medici, a historical figure in the 16th century. When she left her home of Florence, Italy, to marry the king of France, she brought along her own cooks, who could prepare spinach the ways that she especially liked. Since this time, dishes prepared on a bed of spinach are referred to as “a la Florentine.”

Culinary Information

Iron:

Spinach is known as a rich source of iron and calcium. According to the United States Department of Agriculture, a 180 gram serving of boiled spinach contains 6.43 mg of iron, whereas one 6 oz. (170 gram) ground hamburger patty contains at most 4.42 mg. Thus spinach does contain a relatively high level of iron, compared to other vegetable and meat sources.

The iron in spinach is poorly absorbed by the body unless eaten with vitamin C. The type of iron found in spinach is non-blood (non-heme), a plant iron, which the body does not absorb as efficiently as blood (heme) iron, found in meat.

The bioavailability of iron is dependent on its absorption. This is influenced by a number of factors. Iron enters the body in two forms: nonheme iron and heme iron. All of the iron in grains and vegetables, and about three fifths of the iron in animal food sources (meats), is nonheme iron. The much smaller remaining portion from meats is heme iron.

The larger portion of dietary iron (nonheme) is absorbed slowly in its many food sources, including spinach. This absorption may vary widely depending on the presence of binders such as fiber or enhancers, such as vitamin C. Therefore, the body’s absorption of non-heme iron can be improved by consuming foods that are rich in vitamin C. However, spinach contains iron absorption inhibiting substances, including high levels of oxalate which can bind to the iron to form ferrous oxalate, which renders much of the iron in spinach unusable by the body, In addition to preventing absorption and use, high levels of oxalates remove iron from the body. But some studies have found that the addition of oxalic acid to the diet may improve iron absorption in rats over a diet with spinach with out additional oxalic acid. However, foods such as spinach that are high in oxalic acid can increase the risk of kidney stones in some people.

Calcium

Spinach also has a high calcium content. However, the oxalate content in spinach also binds with calcium decreasing its absorption. Calcium and zinc also limit iron absorption. The calcium in spinach is the least bioavailable of calcium sources.By way of comparison, the body can absorb about half of the calcium present in broccoli, yet only around 5% of the calcium in spinach. Oxalate is one of a number of factors that can contribute to gout and kidney stones. Equally or more notable factors contributing to calcium stones are: genetic tendency, high intake of animal protein, excess calcium intake, excess vitamin D, prolonged immobility, hyperparathyroidism, renal tubular acidosis, and excess dietary fiber.

Other

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. 

Types Of Spinach

A distinction can be made between older varieties of spinach and more modern varieties. Older varieties tend to bolt too early in warm conditions. Newer varieties tend to grow more rapidly but have less of an inclination to run up to seed. The older varieties have narrower leaves and tend to have a stronger and more bitter taste. Most newer varieties have broader leaves and round seeds.

There are three basic types of spinach:

Savoy has dark green, crinkly and curly leaves. It is the type sold in fresh bunches in most supermarkets. One heirloom variety of savoy is Bloomsdale, which is somewhat resistant to bolting.

Flat/smooth leaf spinach has broad smooth leaves that are easier to clean than savoy. This type is often grown for canned and frozen spinach, as well as soups, baby foods, and processed foods.

Semi-savoy is a hybrid variety with slightly crinkled leaves. It has the same texture as savoy, but it is not as difficult to clean. It is grown for both fresh market and processing. Five Star is a widely grown variety and has good resistance to running up to seed.

Production, Marketing And Storage

Popeye the Sailor Man has a strong affinity for spinach, becoming physically stronger after consuming it. This is partially due to the iron content being mistakenly reported ten times the actual value, a value that was rechecked during the 1930s, where it was revealed that the original German scientist, Dr. E. von Wolf, had misplaced a decimal point in his calculations.

In truth, spinach actually has about the same iron content as a lot of other vegetables, and even less than others. Cooked broccoli and cauliflower, for example, have almost double the iron content of spinach.

Spinach, along with brussels sprouts and other green vegetables, is often considered in children’s shows to be undesirable.

Palak Paneer

Morus or Mulberry is a genus of 10–16 species of deciduous trees native to warm temperate and subtropical regions of Asia, Africa, Europe, and the Americas, with the majority of the species native to Asia.

The closely related genus Broussonetia is also commonly known as mulberry, notably the Paper Mulberry, Broussonetia papyrifera.

Mulberries are fast-growing when young, but soon become slow-growing and rarely exceed 10-15 metres (33-49 ft) tall. The leaves are alternately arranged, simple, often lobed, more often lobed on juvenile shoots than on mature trees, and serrated on the margin.

The fruit is a multiple fruit, 2-3 centimetres (0.8-1.2 in) long. The fruits when immature are white or green to pale yellow with pink edges. In most species the fruits are red when they are ripening. A fully ripened mulberry in these species is dark purple to black, edible, and sweet with a good flavor in several species. The fruits of the white-fruited cultivar of the White Mulberry on the other hand are green when unripe and white when ripe; the fruit in this cultivar is sweet, and has a very mild flavor compared with the dark fruits.

Uses And Cultivation

The ripe fruit is edible and is widely used in pies, tarts, wines and cordials. The fruit of the black mulberry, native to southwest Asia, and the red mulberry, native to eastern North America, have the strongest flavor. The fruit of the white mulberry, an east Asian species which is extensively naturalized in urban regions of eastern North America, has a different flavor, sometimes characterized as insipid. The mature plant contains significant amounts of resveratrol, particularly in stem bark. The fruit and leaves are sold in various forms as nutritional supplements.

Unripe fruit and green parts of the plant have a white sap that is intoxicating and mildly hallucinogenic.

Black, red and white mulberry are widespread in Northern India, Azerbaijan, Syria, Armenia, Pakistan, Iran, and Afghanistan, where the tree and the fruit are known by the Persian-derived names toot (mulberry) or shahtoot (King’s or “superior” mulberry). Jams and sherbets are often made from the fruit in this region. Black mulberry was imported to Britain in the 17th century in the hope that it would be useful in the cultivation of silkworms. It was much used in folk medicine, especially in the treatment of ringworm.

Mulberry leaves, particularly those of the white mulberry, are ecologically important as the sole food source of the silkworm (Bombyx mori, named after the mulberry genus Morus), the pupa/cocoon of which is used to make silk. Other Lepidoptera larvae also sometimes feed on the plant including common emerald, lime hawk-moth and the sycamore.

Mulberries can be grown from seed, and this is often advised as seedling-grown trees are generally of better shape and health. But they are most often planted from large cuttings which root readily.

The tree branches pruned during the fall season (after the leaves have fallen) are cut and used to make very durable baskets which are used in a lot of village jobs related to agriculture and animal husbandry.

Anthocyanins From Mulberry Fruit

Anthocyanins are pigments which hold potential use as dietary modulators of mechanisms for various diseases and as natural food colorants. As the safety of synthetic pigments is doubted and in the wake of increasing demand for natural food colorants, their significance in the food industry is increasing. Anthocyanins yield attractive colors of fresh plant foods such as orange, red, purple, black and blue. Since they are water-soluble, they are easily extractable and incorporated into aqueous food systems.

A cheap and industrially feasible method to purify anthocyanins from mulberry fruit which could be used as a fabric tanning agent or food colorant of high color value (of above 100) has been established. Scientists found that out of 31 Chinese mulberry cultivars tested, the total anthocyanin yield varied from 148 mg to 2725 mg per liter of fruit juice. Total sugars, total acids and vitamins remained intact in the residual juice after removal of anthocyanins and that the residual juice could be fermented in order to produce products such as juice, wine and sauce.

Worldwide, mulberry is grown for its fruit. In traditional and folk medicine, the fruit is believed to have medicinal properties and is used for making jam, wine, and other food products. As the genera Morus has been domesticated over thousands of years and constantly been subjected to heterosis breeding (mainly for improving leaf yield), it is possible to evolve breeds suitable for berry production, thus offering possible industrial use of mulberry as a source of anthocyanins for functional foods or food colorants which could enhance the overall profitability of sericulture.

Anthocyanin content depends on climate, area of cultivation and is particularly higher in sunny climates. This finding holds promise for tropical sericulture countries to profit from industrial anthocyanin production from mulberry through anthocyanin recovery.

This offers a challenging task to the mulberry germplasm resources for:

-exploration and collection of fruit yielding mulberry species

-their characterization, cataloging and evaluation for anthocyanin content by using traditional as well as modern means and biotechnology tools

-developing an information system about these cultivars or varieties

-training and global coordination of genetic stocks

-evolving suitable breeding strategies to improve the anthocyanin content in potential breeds by collaboration with various research stations in the field of sericulture, plant genetics and breeding, biotechnology and pharmacology.

The cucumber (Cucumis sativus) is a widely cultivated plant in the gourd family Cucurbitaceae, which includes squash, and in the same genus as the muskmelon.

Etymology

The English word cucumber originated from Indian word “kachumbar”(कचुँबर) and in Urdu we say “Kheera”.

Botany

The cucumber is a creeping vine that roots in the ground and grows up trellises or other supporting frames, wrapping around ribbing with thin, spiraling tendrils. The plant has large leaves that form a canopy over the fruit.

The fruit is roughly cylindrical, elongated, with tapered ends, and may be as large as 60 cm long and 10 cm in diameter. Cucumbers grown to be eaten fresh (called slicers) and those intended for pickling (called picklers) are similar. Cucumbers are mainly eaten in the unripe green form. The ripe yellow form normally becomes too bitter and sour.

Having an enclosed seed and developing from a flower, cucumbers are scientifically classified as fruits. Much like tomatoes and squash, however, their sour-bitter flavor contributes to cucumbers being perceived, prepared and eaten as vegetables, which is the accepted culinary term.

Flowering And Polination

A few varieties of cucumber are parthenocarpic, the blossoms creating seedless fruit without pollination. Pollination for these varieties degrades the quality. In the US, these are usually grown in greenhouses, where bees are excluded. In Europe, they are grown outdoors in some regions, and bees are excluded from these areas. Most cucumber varieties, however, are seeded and require pollination. Thousands of hives of honey bees are annually carried to cucumber fields just before bloom for this purpose. Cucumbers may also be pollinated by bumblebees and several other bee species.

Symptoms of inadequate pollination include fruit abortion and misshapen fruit. Partially pollinated flowers may develop fruit which are green and develop normally near the stem end, but pale yellow and withered at the blossom end.

Traditional varieties produce male blossoms first, then female, in about equivalent numbers. New gynoecious hybrid cultivars produce almost all female blossoms. However, since these varieties do not provide pollen, they must have interplanted a pollenizer variety and the number of beehives per unit area is increased. Insecticide applications for insect pests must be done very carefully to avoid killing off the insect pollinators.

Taste

There appears to be variability in the human olfactory response to cucumbers, with the majority of people reporting a mild, almost watery flavor or a light melon taste, while a small but vocal minority report a highly repugnant taste, some say almost perfume-like. The presence of the organic compound phenylthiocarbamide is believed to cause the bitter taste.

Pickling

Cucumbers can be pickled for flavor and longer shelf life. As compared to eating cucumbers, pickling cucumbers tend to be shorter, thicker, less regularly-shaped, and have bumpy skin with tiny white- or black-dotted spines. They are never waxed. Color can vary from creamy yellow to pale or dark green. Pickling cucumbers are sometimes sold fresh as “Kirby” or “Liberty” cucumbers. The pickling process removes or degrades much of the nutrient content, especially that of vitamin C. Pickled cucumbers are soaked in brine or a combination of vinegar and brine, although not vinegar alone, often along with various spices. Pickled cucumbers are often referred to simply as “pickles” in the U.S. or “Gherkins” or “Wallies” in the U.K, the latter name being more common in the north of England where it refers to the large vinegar-pickled cucumbers commonly sold in fish & chip shops. (Although the gherkin is of the same species as the cucumber it is of a completely different cultivar).

Industry

In the United States, consumption of pickles has been slowing, while consumption of fresh cucumbers is rising. In 1999, the consumption in the U.S. totalled 3 billion pounds of pickles with 171,000 acres (690 km2) of production across 6,822 farms and an average farm value of $452 million. According to FAO, China produced at least 60% of the global output of cucumber and gherkin in 2005, followed at a distance by Turkey, Russia, Iran and the United States.

Cultivation Studies

The usual commercial method of cultivating cucumbers involves the use of mineral (manufactured) fertiliser. However, a study in 2004 in Finland by the Department of Environmental Sciences at the University of Kuopio (Helvi Heinonen-Tanski, Annalena Sjöblom, Helena Fabritius and Päivi Karinen) showed that pure human urine can be used as more than just a substitute. Crop yields compared favorably, and taste and microorganism content did not appear to be negatively affected.
