Abstract:
... Fiber quality improvement of upland cotton (Gossypium hirsutum L.) is essential to increase the value and competitiveness of cotton fiber. The closely related allotetraploid species G. barbadense L. has long been targeted as a source of beneficial fiber quality alleles. Although interspecific hybridization between G. hirsutum and G. barbadense results in fertile offspring, cultivar development pro ...

Abstract:
... The performance of plant growth regulators (PGRs) in turfgrass is closely related to air temperature. Growing degree‐days (GDD) have been used to predict the performance of a foliar‐absorbed PGR, trinexapac‐ethyl (TE), on creeping bentgrass (Agrostis stolonifera L.). Similar models have not been attempted for paclobutrazol, a root‐absorbed PGR. This research aimed to develop GDD models (base tempe ...
