Abstract:
... Tropospheric ozone (O(3)) causes significant disruption of growth and yield in upland and Pima cottons. Pima cotton (Gossypium barbadense L.) was exposed to brief pulses (0.75 h) of a range of O(3) concentrations (nominally 0.0, 0.2, 0.5, and 0.8 microliter l(-1)) to investigate effects on phloem translocation of (14)C-labelled recent photo-assimilate. The initial phase of rapid efflux from source ...

Abstract:
... American Pima cotton (Gossypium barbadense L.) is an extra-long staple cotton produced in the southwestern USA and in other regions around the world. Pima cotton generally yields less than Upland (G. hirsutum L.), but there have not been any studies conducted to document the basis for these differences. Field trials were conducted at two south-central Arizona locations from 1990 through 1992 for t ...

We developed a model based on data collected by spraying various amounts o ...

Abstract:
... Interspecific chromosome substitution is among the most powerful means of introgression and steps toward quantitative trait locus (QTL) identification. By reducing the genetic "noise" from other chromosomes, it greatly empowers the detection of genetic effects by specific chromosomes on quantitative traits. Here, we report on such results for 14 cotton lines (CS-B) with specific chromosomes or chr ...

Abstract:
... The Pima cotton (Gossypium barbadense L.) plant is inherently late maturing and unsuitable for production in areas where highly probable late-season rainfall coincides with boll opening. A field study was conducted between 1990 and 1992 to determine if the maturity of Pima cotton can be enhanced with applied N and P without reducing lint yield. Five preplant-applied N rates up to 180 kg ha⁻¹ in 19 ...

Abstract:
... In recent years, there has been slow progress in improving cotton yield. It is known that the F₁ generation from the cross of the new red mutant and the normal green leaf plant has high photosynthetic efficiency. Therefore, cloning the new red mutant gene and further introducing it into other crops through transgenic techniques is a promising approach for achieving high photosynthetic efficiency t ...
