摘要： Planting density plays an important role in improving cotton yield and regulating fiber quality. A 2-year experiment was conducted to investigate the effects of plant density on sucrose metabolism in relation to fiber quality of field-grown cotton. The results showed that lint yield increased with increasing plant density, fiber micronaire, fiber maturity ratio, and fiber fineness decreased with the increasing of plant density, whereas fiber length, fiber uniformity index, fiber strength, and fiber elongation were little affected by plant density. Increased plant density decreased sucrose synthase (SuSy) activity, sucrose content, and cellulose content in cotton fiber, but increased invertase activity. Increased invertase activity would restrain SuSy activity in cotton fiber: therefore, SuSy activity was the most severely affected enzyme in fiber sucrose metabolism by cotton plant density during fiber development. Abundant sucrose content in fiber after 24 days post anthesis (DPA) and high activities of SuSy and sucrose phosphate synthase (SPS) at 38 DPA were beneficial for cellulose synthesis, and were propitious to optimize the fiber maturity properties. The results also showed that fiber micronaire, maturity ratio, and fineness decreased 0.11, 0.02, and 5.89 mtex, respectively, with each increase of 10,000 plants per hectare. It was concluded that high plant density decreased SuSy activity, sucrose content, and cellulose content, but increased invertase activity in sucrose metabolism, resulting in low fiber micronaire, fiber maturity ratio, and fiber fineness.
