Fiber perimeter directly affects such cotton fiber properties as length, strength, and micronaire. A study measured changes in maximum fiber diameter, fiber length, and cell wall birefringence throughout the development of cotton genotypes MD51ne, DP50, and DP90; Gossypium hirsutum cultivars; and G. barbadense cultivars. During the first 30 days of fiber development, DP90 had the smallest change in fiber diameter (33 percent), followed by 35 percent for G. barbadense, 42 percent for MD51ne, and 62.5 percent for DP50. Simultaneous increases in fiber diameter and cell wall birefringence from days 20-30 postantheses for all genotypes indicated that the secondary cell wall was not rigid and that fiber perimeter was a dynamic fiber property. Modulating fiber diameter during this long window can provide a new method for changing fiber development to improve cotton properties. Abstract. 39 refs.
