As both Pima cotton (Gossypium barbadense L.) and Acala (Upland; G. hirsutum L.) are grown in the southwestern United States, understanding gene fl ow within and among these species is important to maintain genetic purity. In small scale and commercial fi elds, gene fl ow decreased exponentially from 1.44% at 1 m to less than 0.50% at 10 m in Acala cotton. Corresponding values for Pima cotton w...

In cotton (Gossypium hirsutum L.) production, the amount of fertilizer input along with plant demand for nutrients can be substantial throughout the growing season. Although conventional fertilization has been instrumental in improving cotton yields, there are drawbacks that accompany their use such as nutrient groundwater leaching and surface runoff, substantial amounts of fossil fuel consumpt...

The effect of abscisic acid on cotton (Gossypium hirsutum L. cv. Acala 4-42) and bean (Phaseolus vulgaris L. cv. Red Kidney) explants was 2-fold. It increased ethylene production from the explants, which was found to account for some of its ability to accelerate abscission. Absci is acid also increased the activity of cellulase. Increased synthesis of cellulase was not du to an increase in agin...

Leaf shapes of cotton (Gossypium hirsutum) range from highly divided leaves (okra leaf) to normal leaf shape (Meredith, 1 ). The variation in leaf shape results in differences in canopy architecture and light interception characteristics (Wells and Meredith, 1 ). Heitholt et al. (1 ) described higher yields of okra leaf isolines for a given amount of intercepted radiation, indicating that the o...

Genetic variation available for the improvement of fiber properties is restricted in commercial upland cotton (Gossypium hirsutum L.). Resources for fiber improvement exist in G. barbadense L., but introgression of traits has been a limited success. The objectives of this study were to investigate the genetic variation and heritability of agronomic and fiber traits within a diverse recombinant ...

The effects of two entomopathogenic fungal endophytes, Beauveria bassiana and Purpureocillium lilacinum (formerly Paecilomyces lilacinus), were assessed on the reproduction of cotton aphid, Aphis gossypii Glover (Homoptera:Aphididae), through in planta feeding trials. In replicate greenhouse and field trials, cotton plants (Gossypium hirsutum) were inoculated as seed treatments with two concent...

The components of lint yield in cotton are the number of plants per acre, the number of bolls per plant, the number of seeds per boll, and the number of fibers per seed. This list may be reduced to the two essential components, i.e., the number of seeds per acre and the weight of fiber per seed. A great deal of attention has been paid to the first factor but the weight of fiber per seed has bee...
