Cotton fibers are single-celled outgrowths from individual epidermal cells on the outer integument of the ovules in the developing cotton fruit. Fibers of upland cotton (G. hirsutum L.) generally grow up to 30 to 40 mm in length and 15 μm in thickness at full maturity. Their development consists of four overlapping stages: fiber initiation, cell elongation, secondary wall deposition, and matur...

Cotton fiber quality traits are controlled by multiple quantitative trait loci (QTL), and the improvement of these traits requires extensive germplasm. Herein, an Upland cotton cultivar from America, Acala Maxxa, was crossed with a local high fiber quality cultivar, Yumian 1, and 180 recombinant inbred lines (RILs) were obtained. In order to dissect the genetic basis of fiber quality difference...

from ambient levels of 360 mol mol 1 increased vegetative biomass by 40% and boll biomass by 20% (Reddy The consequences of elevated carbon dioxide concentrations et al., 1997). Open-top chamber experiments (Kimball ([CO2]) and N nutrition on cotton (Gossypium hirsutum L.) growth, and Mauney, 1993) showed that elevated [CO2] of 650 development, yield, and fiber quality were determined. Cotton c...

Anaerobic digestion of dairy cow manure (CM), the organic fraction of municipal solid waste (OFMSW), and cotton gin waste (CGW) was investigated with a two-phase pilot-scale anaerobic digestion (AD) system. The OFMSW and CM were digested as single wastes and as combined wastes. The single waste digestion of CM resulted in 62m3 methane/ton of CM on dry weight basis. The single waste digestion of...

Since textile waste recycling is a global challenge, there an emerging need to explore this research direction due the little knowledge about recycling. This study aimed property of yarns produced from recycled textile/cotton fiber blends for proportion optimization and check whether they can be used denim fabric production. The properties virgin cotton spun on open-end having 4.5 Ne were inves...

for this reason the samples were obtained from three area in kerman province that cartivate corn in large amounts (giroft, kahnooj, baft).the amounts of samples were enough for both voluntary consumption and investigation of digestibility. after that samples had been chopped by electric chopper we sampled again from every sample and its chemical compositions were determined with standard method...

Plant type III polyketide synthase (PKS) can catalyse the formation of a series of secondary metabolites with different structures and different biological functions; the enzyme plays an important role in plant growth, development and resistance to stress. At present, the PKS gene has been identified and studied in a variety of plants. Here, we identified 11 PKS genes from upland cotton (Gossyp...

Phytophagous stink bugs are economically important pests of annual and perennial crops in the southeastern United States. Because of insecticide resistance and risk of secondary pest outbreaks, there is interest in identifying cultural practices that could lead to reduced insecticide applications. The objective of this project was to assess the importance of cotton planting date on stink bug da...

Cotton has lost many ancestral defensive traits against key invertebrate pests. This is suggested by the levels of resistance to some pests found in wild cotton genotypes as well as in cultivated landraces and is a result of domestication and a long history of targeted breeding for yield and fiber quality, along with the capacity to control pests with pesticides. Genetic modification (GM) allow...
