| Popis: | Increasing cotton (Gossypium hirsutum L.) fiber weight per seed in some genotypes has the potential to increase micronaire values to levels that trigger price discounts. Strategies need to be developed that limit cell wall deposition. Seed weight decreases as the number of seeds per boll increases. Characterization of the relationship between seed weight, fibers per seed and fiber properties will supply basic information for strategy development. Stoneville 474 and FiberMax 832 were grown under irrigated conditions in 1998 and 1999. First position flowers were harvested on the day of anthesis for fiber density and perimeter analysis. Remaining first position bolls were harvested after boll opening and bolls were individually analyzed for weight and fiber properties. Initial fiber densities were similar for both cultivars. Mean fiber length and cell wall thickness were positively correlated with final seed weight. Fiber length variability decreased as seed weight increased. The decrease in length ... |
