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 identification of molecular markers linked to leaf curl virus (clcuv) disease resistance in cotton has the potential to improve both the efficiency and the efficacy of selection in cotton breeding programs. genetic analysis suggested that clcuv resistance is controlled by a single dominant gene. in this study, an interspecific f2 population derived from a cross of gossypium barbadense and g...
La familia Malvaceae cuenta con especies ampliamente distribuidas a nivel mundial, algunas de ellas, tales como el algodón (Gossypium hirsutum), cacao (Theobroma cacao) y la jamaica (Hibiscus sabdarif fa) son utilizadas en industria agroalimentaria o textil; aun así no todo potencial bioactivo estas ha sido aprovechado, tal es caso H. fa, ya que su mayoría, las semillas consideradas desecho agr...
