本文是从棉花花芽分化发育动态来研究棉桃的形成过程。试验结果表明:(1)棉株生长至有效蕾终止期(8月15日)可分化113～134个花芽(一级果枝花芽),能现蕾开花的有40～54个,能成桃的有9.8～15.6个,成铃率为7.8～11.6%,(2)棉株现蕾前可分化21～30个花芽,一般都有可能现蕾开花;蕾期可分化57～61个花芽,其中有10～30个花芽能现蕾开花,其余为无效花芽。开花后可分化22～48个花芽为无效花芽。
In this paper, the development of cotton buds from cotton flower bud development to study the formation of cotton bolls. The results showed that: (1) The cotton plants could grow from 113 to 134 flower buds (first-stage fruit buds) when they grew till effective termination of the bud (August 15), 40 ~ 54 buds could flowering, 9.8 ~ 15.6, and the boll rate was 7.8 ~ 11.6%. (2) The cotton plants could differentiate from 21 to 30 flower buds before budding, and buds were generally likely to flower buds; buds could differentiate from 57 to 61 buds, of which 10 to 30 flower buds can flower buds, the rest is invalid flower buds. Differentiation after flowering 22 to 48 flower buds as invalid flower buds.
