Pachyrhizus
''Pachyrhizus'' is a small genus of five or six species of tropical and subtropical plants growing from large, often edible taproots. Jícama The jícama or yam bean (''P. erosus'') is a vine widely grown for its large (10–15 cm diameter and up to 20 kg weight), spherical or elongated taproot. After removal of the thick, fibrous brown skin, the white flesh of the root can be eaten cooked or raw. Crisp, moist, and slightly sweet, the flesh draws comparison with that of the apple. The plant produces seeds that are comparable to lima beans, and that are sometimes eaten when young in places where the jicama is native. The mature seeds contain high levels of rotenone, a chemical used as an insecticide and pesticide. The remainder of the jícama plant is very poisonous. Jícama comes from the New World; the name jícama is used in Central / South America. Today, pachyrhizus erosus is grown throughout Asia. In China, the root is known as cold potato; in Malaysia, sen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pachyrhizus Erosus
''Pachyrhizus erosus'', commonly known as jícama ( or ; Spanish ''jícama'' ; from Nahuatl ''xīcamatl'', ) Mexican turnip, is the name of a native Mexican vine, although the name most commonly refers to the plant's edible tuberous root. Jícama is a species in the ''Pachyrhizus'' erosus in the pea family. (Fabaceae). ''Pachyrhizus tuberosus'' and ''Pachyrhizus ahipa'' are the other two cultivated species. The naming of this group of edible plants can sometimes be confusing, with much overlap of similar or the same common names. Flowers, either blue or white, and pods similar to peas, are produced on fully developed plants. Several species of jicama occur, but the one found in many markets is ''P. erosus''. The two cultivated forms of ''P. erosus'' are ''jicama de agua'' and ''jicama de leche'', both named for the consistency of their juice. The ''leche'' form has an elongated root and milky juice, while the ''agua'' form has a top-shaped to oblate root and a more wat ...

Root Vegetables
Root vegetables are underground plant parts eaten by humans as food. Although botany distinguishes true roots (such as taproots and tuberous roots) from non-roots (such as bulbs, corms, rhizomes, and tubers, although some contain both hypocotyl and taproot tissue), the term "root vegetable" is applied to all these types in agricultural and culinary usage (see terminology of vegetables). Potatoes are technically tubers, not roots, and sweet potatoes are tuberous roots. Root vegetables are generally storage organs, enlarged to store energy in the form of carbohydrates. They differ in the concentration and the balance among starches, sugars, and other types of carbohydrate. Of particular economic importance are those with a high carbohydrate concentration in the form of starch; starchy root vegetables are important staple foods, particularly in tropical regions, overshadowing cereals throughout much of Central Africa, West Africa and Oceania, where they are used directly or mashed ...

Phaseoleae
The plant tribe Phaseoleae is one of the subdivisions of the legume subfamily Faboideae, in the unranked NPAAA clade. This group includes many of the beans cultivated for human and animal food, most importantly from the genera ''Glycine'', '' Phaseolus'', and ''Vigna''. Taxonomy Although the tribe as defined in the late 20th century does not appear to be monophyletic, there does seem to be a monophyletic group which roughly corresponds to the tribe Phaseoleae (with some changes). The earlier concept of Phaseoleae is paraphyletic relative to the tribes Abreae and Psoraleeae, plus most of Millettieae and parts of Desmodieae. The following subtribes and genera are recognized by the USDA: ollow tribe links and genera lists for the accepted genera in each tribe/ref> ;Cajaninae * '' Adenodolichos'' Harms * ''Bolusafra'' Kuntze * ''Cajanus'' Adans. * ''Carrissoa'' Baker f. * ''Chrysoscias'' E.

Rotenone
Rotenone is an odorless, colorless, crystalline isoflavone used as a broad-spectrum insecticide, piscicide, and pesticide. It occurs naturally in the seeds and stems of several plants, such as the jicama vine plant, and the roots of several members of Fabaceae. It was the first described member of the family of chemical compounds known as rotenoids. Discovery The earliest record of the now-known rotenone-containing plants used for killing leaf-eating caterpillars was in 1848, and for centuries, the same plants were used to poison fish. The active chemical component was first isolated in 1895 by a French botanist, Emmanuel Geoffroy, who called it ''nicouline'', from a specimen of ''Robinia nicou'', now called ''Lonchocarpus nicou'', while traveling in French Guiana. He wrote about this research in his thesis, published in 1895 after his death from a parasitic disease. In 1902 Kazuo Nagai, Japanese chemical engineer of the Government-General of Taiwan, isolated a pure crystalline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lima Bean
A lima bean (''Phaseolus lunatus''), also commonly known as the butter bean, sieva bean, double bean, Madagascar bean, or wax bean is a legume grown for its edible seeds or beans. Origin and uses ''Phaseolus lunatus'' is found in Meso- and South America. Two gene pools of cultivated lima beans point to independent domestication events. The Mesoamerican lima bean is distributed in neotropical lowlands, while the other is found in the western Andes. They were discovered in Peru and may have been the first plant that was brought up under civilization by the native farmers. The Andes domestication took place around 2000 BC and produced a large-seeded variety (lima type), while the second, taking place in Mesoamerica around 800 AD, produced a small-seeded variety (Sieva type). By around 1300, cultivation had spread north of the Rio Grande, and, in the 1500s, the plant began to be cultivated in the Old World. The small-seeded (Sieva) type is found distributed from Mexico to Argent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple fruit tree, trees are agriculture, cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonization of the Americas, European colonists. Apples have Religion, religious and mythology, mythological significance in many cultures, including Norse mythology, Norse, Greek mythology, Greek, and Christianity in Europe, European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after plantin ...

Poison
Poison is a chemical substance that has a detrimental effect to life. The term is used in a wide range of scientific fields and industries, where it is often specifically defined. It may also be applied colloquially or figuratively, with a broad sense. Whether something is considered a poison may change depending on the amount, the circumstances, and what living things are present. Poisoning could be accidental or deliberate, and if the cause can be identified there may be ways to neutralise the effects or minimise the symptoms. In biology, a poison is a chemical substance causing death, injury or harm to organisms or their parts. In medicine, poisons are a kind of toxin that are delivered passively, not actively. In industry the term may be negative, something to be removed to make a thing safe, or positive, an agent to limit unwanted pests. In ecological terms, poisons introduced into the environment can later cause unwanted effects elsewhere, or in other parts of the food ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...
