Abstract:
... Because reproductive growth could be influenced by sucrose metabolism of major source leaf (leaf subtending to cotton boll, LSCB), we hypothesized that decreased temperatures under field conditions would limit morphology and biomass distributions of the whole cotton plant by decreasing photosynthesis of LSCB and inhibiting sucrose metabolism in LSCB. To address this hypothesis, two cotton cultivar ...

Abstract:
... Cotton is the world’s leading natural fiber and second most important oilseed crop and has been a focus of genetic, systematic and breeding research. The genetic and physiological bases of some important agronomic traits in cotton were investigated by QTL mapping through constructing of genetic map with chromosomal assignment. A segregating F2 population derived from an interspecific cross (G. bar ...

Abstract:
... Modern cotton (Gossypium hirsutum L.) cultivars with herbicide resistance have rejuvenated an interest in narrow row cotton production, primarily because of the reduction of weed control problems encountered in the past with narrow row systems. While the primary goal of narrow row cotton is to reduce production costs, an agronomic and physiological evaluation of this cropping system is also needed ...

Abstract:
... The boll distribution characteristics of upland cotton (Gossypium hirsutum L.) cultivars are related to cotton maturity and can interact with environment and management practices to determine yield and fiber quality. The boll distributions of six cotton cultivars under four irrigation levels were compared in 2011 and 2012 on the Texas High Plains. In 2011, a year of severe drought and heat, all cu ...

Abstract:
... The ability to monitor verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), and the progression of cotton, Gossypium hirsutum L., boll responses to feeding and associated cotton boll rot provided opportunity to assess if single in-season measurements had value in evaluating at-harvest damage to bolls and if multiple in-season measurements enhanced their combined use. One in-season v ...
