摘要
棉铃发育过程中，苏杂１６单铃子棉主的提高表现为二个方面：一是纤维干重的增加，１９９１～１９９２两年平均增加１０．０％；二是种子重量的提高，两年平均单铃种仁重增加９．４％。单铃纤维干重的增长与棉铃对位叶大小呈正相关关系，与棉铃对位叶中全Ｎ含量呈负相关关系．该杂文组合在棉铃发育过程中表现了较强的“源”“库”生理优势，光合产物积累多，营养物质运转快是该组合获得高产的重要生理基础。
During the development of the boll,the incren1ent of single boll of cotton variety SUZA16 lies on,according to the average of two years 1991 and 1992,the dry weight of fiber increase by 10%;and the weight of kernel by 9.4%. There is a positive relation be-tween the dry weight of single boll and the size of leaves,and the negative one betwen the dry weight of single boll and the total N in the leaves,The hybrid cotton showed the phys- iological heterosis of source and sink during the development of bolls,More accumulation of photosysthesis products and transportation of nutrient substance is the reason that the hybird gains high output.
