Increased lint yields of cotton (Gossypium hirsutum L.) cultivars during recent years have been accompanied by increased percentages and decreased seed size. Small size can be associated with low seedling vigor contribute to ginning problems. In contrast, large thin coats lower yields. Our objective was develop an index that would characterize weight per seed. Seed-score (S-score) attempts norm...

Restricted water resources are a limiting factor for irrigation applications throughout the world. The effects of irrigation regimes (amount) on cotton lint yield are known, but there is little information on the effect of irrigation regimes on seed quality of cotton. In this study, the effects of deficit irrigation after the onset of flowering on lint yield and seed quality of cotton (Gossypiu...

Cotton (Gossypium hirsutum L.) production in Oklahoma has more than tripled the last ten years. This increase cotton acreage Oklahoma, a region that traditionally produces winter wheat, led to increased incidences of 2,4 D contamination sprayers are used spray crops. is extremely sensitive D, with losses yield and ultimately profit producer cases drift or tank carryover. In this study, six cult...

One of the most striking examples of plant hairs is the single-celled epidermal seed trichome of cultivated cotton. The developmental morphology of these commercial "fibers" has been well-characterized in Gossypium hirsutum, but little is known about the pattern and tempo of fiber development in wild Gossypium species, all of which have short, agronomically inferior fiber. To identify developme...

The PIN-FORMED (PIN) protein, the most important polar auxin transporter, plays a critical role in the distribution of auxin and controls multiple biological processes. However, characterizations and functions of this gene family have not been identified in cotton. Here, we identified the PIN family in Gossypium hirsutum, Gossypium arboreum, and Gossypium raimondii. This gene family was divided...
