Results for Gossypium
On this page:
 

Includes G. hirsutum (Gossypium arboreum, G. barbadense, G. herbaceum), the commercial cotton plant of the family Malvaceae.
Cotton seeds are a residue of the cotton industry and, after extraction of the oil, the residual cottonseed cake is much valued as a protein supplement for livestock. The seeds contain gossypol, a toxic polyphenolic pigment, and unless the processing is appropriate the cake and meal can be very poisonous, causing severe myocardial necrosis and liver damage. Ruminants may be affected but the severest disease occurs in pigs. Clinically there is congestive heart failure and severe dyspnea. The cake is also very low in vitamin A and nutritional deficiency may result.

Species

See text.

Gossypium is a genus of 39-40 species of shrubs in the family Malvaceae, native to the tropical and subtropical regions of both the Old World and the New World. The cotton plants, sources of commercial cotton fabric, are included in this genus.

Cotton shrubs can grow up to 3 m (10 ft) high. The leaves are broad and lobed, with three to five (or rarely seven) lobes. The seeds are contained in a capsule called a boll, each seed surrounded by downy fibres called lint. Commercial species of cotton plant are G. hirsutum (90% of world production), G. barbadense (8%), G. arboreum and G. herbaceum (together, 2%). While the lint (fiber) naturally occurs in colors of white, brown, and green, fears of contaminating the genetics of white cotton has led many cotton-growing locations to ban growing of coloured cotton varieties.

Species of Gossypium

Commercial cotton species

Commercial cotton fibres, used to manufacture cloth, are derived from the fruit of the cotton plant. The following species are grown commercially:

Non-commercial species

Many varieties of cotton have been developed by selective breeding and hybridization of the above species. Experiments are ongoing to cross-breed various desirable traits of wild cotton species into the principal commercial species, such as resistance to insects, disease and drought-tolerance.
