Comparison of Relative Enzymes Activities during Fiber Development Period between Brown and White Fiber Cotton Cultivars Abstract: This experiment was carried out to study the effect of relative enzymes activities on brown cotton fiber qualities, three kinds of brown cottons (dark brown, mid-brown and light brown) were used to detect the dynamics of relative enzymes activities in contrast with one white cotton. The results showed that the length of fiber, lint weight and lint percentage of brown cotton were lower than white cotton. During the fiber development, the elongation rate of brown cotton was lower and the elongation term was shorter than white cotton. Comparing with white cotton, brown cotton had shorter term, lower cellulose accumulation rate and cellulose content for fiber. At the early periods of fiber development, SS activity was lower in brown fiber, while POD and IAAO activities were higher. At the later periods of fiber development, ¦Â-1, 3-glucanase and POD activities were lower in brown fiber.
