Apricot

Apricot first appeared in English in the 16th century as abrecock from the Middle French or later , from Spanish albaricoque and Catalan , in turn from Arabic (, ), from Byzantine Greek (, ), derived from late Greek (, ) from Latin [ ()] (, ). The specific epithet armeniaca refers to the country of Armenia. of "apricot" from Latin via Late and Byzantine Greek to Arabic, Spanish and Catalan, Middle French, and so to English == Description ==

The apricot is a small tree, up to tall, with a round canopy and a spread similar to its height. The flowers are white or pinkish, about wide, appearing before the leaves early in the spring. The fruit is a succulent orange-yellow drupe (a stonefruit) tinged with red. The single seed (kernel or stone) is enclosed in a hard shell (exocarp).

Apricots are species belonging to Prunus sect. Armeniaca. The taxonomic position of P. brigantina is disputed. It is grouped with plum species according to chloroplast DNA sequences, but more closely related to apricot species according to nuclear DNA sequences. • Prunus armeniaca – common apricot, widely cultivated for its edible fruit and kernel • Prunus brigantina – Briançon apricot, native to Europe, cultivated for its edible fruit and oil-producing kernel • Prunus cathayana – native to Hebei • Prunus × dasycarpa – purple apricot, cultivated in Central Asia and adjacent areas for its edible fruit • Prunus hongpingensis – Hongping apricot, native to Shennongjia, cultivated for its edible fruit • Prunus hypotrichodes – native to Chongqing • Prunus limeixing – cultivated in northern China for its edible fruit • Prunus mandshurica – Manchurian apricot, native to Northeast Asia, cultivated for its kernel, the fruits of some cultivars edible • Prunus mume – flowering apricot, native to southern China, widely cultivated for its beautiful blossom and edible fruit • Prunus sibirica – Siberian apricot, native to Siberia, Mongolia, northern China, and Korea, cultivated for its kernel • Prunus zhengheensis – Zhenghe apricot, native to Fujian == Cultivation ==

Origin and domestication . The Petrie Museum of Egyptian Archaeology The most commonly cultivated apricot Prunus armeniaca was known in Armenia during ancient times, and has been cultivated there for so long that it was previously thought to have originated there, hence the epithet of its scientific name. However, this is not supported by genetic studies, which instead confirm the hypothesis proposed by Nikolai Vavilov that domestication of P. armeniaca occurred in Central Asia and China. The domesticated apricot then diffused south to South Asia, Cultivation practices Apricots have a chilling requirement of 300 to 900 chilling units. A dry climate is good for fruit maturation. The tree is slightly more cold-hardy than the peach, tolerating winter temperatures as cold as or lower if healthy, with large differences between cultivars. They are hardy in USDA zones 5 through 8. A limiting factor in apricot culture is spring frosts: They tend to flower very early (in early March in western Europe), and spring frost can kill flowers or before flower buds in different stages of development. Apricots prefer well-drained soils with a pH of 6.0 to 7.0. Apricot cultivars are usually grafted onto plum or peach rootstocks. The cultivar scion provides the fruit characteristics, such as flavor and size, but the rootstock provides the growth characteristics of the plant. Some of the more popular US apricot cultivars are 'Blenheim', 'Wenatchee Moorpark', 'Tilton', and 'Perfection'. Some apricot cultivars are self-compatible, so do not require pollinizer trees; others are not: 'Moongold' and 'Sungold', for example, must be planted in pairs so they can pollinate each other. Plant breeders have created what is known as a "black apricot" or "purple apricot", (Prunus dasycarpa), a hybrid of an apricot and the cherry plum (Prunus cerasifera). Other apricot–plum hybrids are variously called plumcots, apriplums, pluots, or apriums.

In California's hot Central Valley, pit burn, a condition of soft and brown fruit around the pit, is common. Bacterial diseases include bacterial spot and crown gall. Fungal diseases include brown rot caused by Monilinia fructicola late in the season. In periods of heavy rain, the flowers can suffer from blossom wilt where the flowers and young shoots turn brown and die; the twigs die back in a severe attack. Dieback of branches in the summer around pruning wounds can be caused by the fungus Eutypa lata. Other fungal diseases are black knot, Alternaria spot and fruit rot, and powdery mildew. Unlike peaches, apricots are not affected by leaf curl, and bacterial canker (causing sunken patches in the bark, which then spread and kill the affected branch or tree) and silver leaf are not serious threats, which means that pruning in late winter is considered safe. Malatya is the center of Turkey's apricot industry. == Toxicity ==

Apricot kernels (seeds) contain amygdalin, a poisonous compound. On average, bitter apricot kernels contain about 5% amygdalin and sweet kernels about 0.9% amygdalin. These values correspond to 0.3% and 0.05% of cyanide. Since a typical apricot kernel weighs 600 mg, bitter and sweet varieties contain, respectively, 1.8 and 0.3 mg of cyanide. == Uses ==

Fruit Fresh apricots can be cooked in dishes such as cakes and tarts, or made into jam. Dried apricots can be used in similar ways, and included in stuffing for meat dishes, stews, granola, and muesli. In Austrian cuisine, Marillenknödel are dumplings stuffed with apricots, garnished with breadcrumbs fried in butter and dusted with sugar. In Mediterranean cuisine, a cooling drink is made by dissolving apricot paste in water. Barack is a Hungarian apricot brandy.

Oil made from apricot kernels is safe for human consumption without treatment because amygdalin is not oil soluble. Ground up shells are used in cosmetics as an exfoliant. As an exfoliant, it provides an alternative to plastic microbeads. The kernels can be made into a plant milk. Nutrition A raw apricot is 86% water, 11% carbohydrates, 1% protein, and less than 1% fat (table). In a reference amount of , a raw apricot supplies 48 Calories and is a moderate source of vitamin A and vitamin C (11% each of the Daily Value, DV), with no other micronutrients in significant content (less than 10% DV, table). Phytochemicals Apricots contain phytochemicals, such as polyphenols, including catechins and chlorogenic acid. Taste and aroma compounds include sucrose, glucose, organic acids, terpenes, aldehydes and lactones. Dried apricots Dried apricots are a type of traditional dried fruit. Dried apricots are 31% water, 63% carbohydrates, 4% protein, and contain negligible fat (table). When the water content of apricots is decreased by drying, the mass fraction of micronutrients is increased, such as for vitamin A, vitamin E, copper and potassium, each having higher contents than in raw fruit (DVs above 20%, table). Wood Apricot wood is used for the production of the duduk, an Armenian woodwind instrument. == In culture ==

The apricot is the national fruit of Armenia, mostly growing in the Ararat plain. It is often depicted on souvenirs. The Chinese associate the apricot with education and medicine. For instance, the classical word 杏 壇 (literally: "apricot altar") (xìng tán 杏坛) which means "educational circle", is still widely used in written language. Zhuangzi, a Chinese philosopher in the fourth century BC, told a story that Confucius taught his students in a forum surrounded by the wood of apricot trees. The association with medicine in turn comes from the common use of apricot kernels as a component in traditional Chinese medicine, and from the story of Dong Feng (董奉), a physician during the Three Kingdoms period, who required no payment from his patients except that they plant apricot trees in his orchard upon recovering from their illnesses, resulting in a large grove of apricot trees and a steady supply of medicinal ingredients. The short and unreliable apricot season in Egypt has given rise to the common Egyptian Arabic and Palestinian Arabic expression filmishmish ("in apricot [season]") or bukra filmishmish ("tomorrow in apricot [season]"), uttered as a riposte to an unlikely prediction, or as a rash promise to fulfill a request. In Middle Eastern and North African cuisines, apricots are used to make Qamar al-Din ( "Moon of the faith"), a thick apricot drink that is a popular fixture at Iftar during Ramadan. Qamar al-Din is believed to originate in Damascus, Syria, where the variety of apricots most suitable for the drink was first grown. In Jewish culture, apricots are eaten as part of the Tu BiShvat seder. In the U.S. Marines it is considered exceptionally bad luck to eat or possess apricots, especially near tanks. This superstition has been documented since at least the Vietnam War and is often cited as originating in World War II. Even calling them by their name is considered unlucky, so they are instead called "cots", "Forbidden fruit" or "A-fruit". American astronauts ate dried apricot on the Apollo 15 and Apollo 17 missions to the moon. ==Gallery==
