新疆棉花播期对棉纤维糖类物质及超分子结构的影响
Effect of Different Sowing Dates on Transformation of Carbohydrate and Super- molecular Structure in Fiber During Cotton Development in Xinjiang
摘要
Abstract
[ Objective ] Effects of different sowing dates on cellulose deposition, fiber super - molecular structure and their relationship to fiber strength were studied in this paper to explore the impact of low temperature on cotton fiber strength in late growth stage of cotton. [ Method] In this paper, Xinluzaol3 and Xinluzao33 were taken as test materials, by setting different cotton seeding dates, changes of characteristic values of cellulose content and fiber super - molecular structure and their relationship to fiber strength were studied. [ Result] Results showed that, under the normal sowing date conditions, cotton fiber development in a more favorable temperature conditions, sucrose converted completely and cellulose accumulated sustainably and steadily,and under the late sowing date conditions, low temperature mainly delayed the initial time of rapid accumulation of cellulose synthesis, reduced the cellulose speedy accumulation period, the content of cellulose decreased and fiber strength was affected by orientational separate angle and distribution angle. [ Conclusion] Lower temperature changed the cellulose accumulation characteristic and fiber super - molecular structure, resulting in lower cellulose content and broader structural parameters, leading to strike decrease of fiber strength.关键词
