| 摘 要： | 5个零型海岛棉品种棉铃发育过程中干物质积累、分配及铃壳生理指标的测定结果显示：（1）铃壳干物质随铃龄直线上升而后迅速下降，种子和子棉干物质积累直线上升。（2）铃壳率逐渐下降，种子率和子棉率逐步增加，最终达到峰值，而纤维重率呈先降后升的现象。（3）光合色素的含量随铃龄逐渐增长，类胡萝卜素、可溶性蛋白质含量、转化酶活性随铃龄增长而减弱。

| Abstract: | By measuring the dry matter accumulation,distribution,and the physiological factors of boll shell during the cotton-boll development process of five kinds of island cotton, we get the results:(1)The dry matter in boll shell increases positively with the age of the cotton-boll,then drops quickly,the dry matter accumulation in seed and seed-cotton keeps a positive rise；(2)The ratio of boll shell in the boll decreases gradually , the ratio of seed and seed-cotton increase step by step , reaching their peaks at the end, while the ratio of pure-cotton exhibits a phenomenon of firstly decrease then increase；(3)The content of photosynthetic pigment goes up with the aging of the cotton-boll, while the content of carotenoid, soluble protein and the activity of invertase goes down, indwidudly. Several suggestions are proposed. |
