Gossypium hirsutum

Biggest Plant Dictionary  | Gossypium hirsutum |  Gossypium hirsutum cotton or very important as a highly profitable industrial plants stout tumbuhab benefit from this. and with history, Archeological evidence from the Tehuacan Valley in Mexico shows the cultivation of this species as long as 5.000 years ago. This is the earliest evidence of cotton cultivation in the Americas found thus far. Gossypium hirsutum includes a number of varieties or cultivars of cross-Bred with varying fiber lengths and tolerances to a number of growing conditions. The longer length varieties are called "Long Staple Upland" and the shorter length varieties are Referred to as "Short Staple Upland". The long staple varieties are the most widely cultivated in commercial production.

Toxicity

Gossypol, the toxic dihydroxyphenol, occuring in seeds and the glands of seedlings, must be removed before cottonseed can be used for feed. Hogs have died from eating raw seed (Morton, 1974). Per 100 g, the ground seed is reported to contain 7.3 g H2O, 23.1 g protein, 22.9 g fat, 43.2 g total carbohydrate, 16.9 g fiber, 3.5 g ash, 140 mg Ca, 1.2 mg Mn, 320 mg Mg, 680 mg P, 14 mg Fe, 290 mg Na, 1,110 mg K 240 mg S, 5 mg Cu. Once the oil is removed, the meal contains per 100 g, 7.3 g H2O, 41.4 g protein, 5.6 g fat, 10.9 g crude fiber, 39.5 g total carbohydrate (6.5 g total sugars, 6.4% lignin), 190 mg Ca, 1.8 mg Cu, 10 mg Fe, 490 mg Mg, 2.3 mg Mn, 1,090 mg P, 1,250 mg K, 50 mg Na, and 400 mg S (Parnell, 1981).

Gossypium hirsutum

Commercial cottonseed contains approximately 92% dry matter, 16–20% protein, 18–24% oil, 30% carbohydrates, 22% crude fiber. After ginning, cottonseed includes unginned lint, fuzz, 16% crude oil, 45.5% cake or meal, 25.5% hulls, and 8% linters. Principal pigment in seed is gossypol, a poisonous phenolic compound usually rendered harmless on crushing or heating, but may retain minute amounts to which pigs and chickens are sensitive.

usefulness
Cultivated primarily for its vegetable seed fiber, the raw material for a large volume of textile products, this species is Considered the most Important of the cotton-yielding plants, providing the bulk of commercial cottons. Linters acres of intermediate texture and shorter than Those of G. barbadense. Seeds yield a semi-drying and edible oil, used in shortening, margarine, salad and cooking oils, and for protective coverings.

Residue, cottonseed cake or meal is Important protein concentrate for livestock. Pigg (1980) reports That bread, made ​​with cottonseed protein is an even better source of protein than enriched white bread, six slices of the which Provide 20% of the adult RDA. Low-grade residue serves as manure, bedding and fuel. Fuzz, the which is not removed in ginning, Become linters in felts, upholstery, mattresses, Twine, Wicks, carpets, surgical cottons, and in chemical industries Such as rayons, film, shatterproof glass, plastics, sausage skins, lacquers, and cellulose Explosives .

Gossypium hirsutum

From
Believed to have originated in Central America. In its transition from tropical to temperate regions, American Upland Cotton has lost the perennial, short-day habit to become highly vegetative producing few or no fruiting branches when grown during long days. Annual forms were developed in which all periodicity controls were lost. American Upland Cotton was taken from Mexico to United States about 1700. During American Civil War, it was introduced into most tropical and subtropical countries of the world.

Gossypium hirsutum

It now forms basis of all commercial cotton crops of Africa outside the Nile Valley, all those of South America except in Peru and northern Brazil, of the modern Russian crop, and much of that of northern India and Pakistan, and the Philippine Islands, as well as that of the Cotton Belt of the United States. Upland and Cambodian varieties are invading the Chinese crop, and where these cottons are developed in southeast Asia, they will be based on these types and hybrids between them.
