从棉花幼苗期至有效蕾终止期对一熟棉、麦套棉不同生育时期、叶龄与果枝、花芽分化发育间的关系进行了观察研究.试验结果表明: (1)与一热棉比较,麦套棉花芽分化期较迟,有效花芽分化期较短,单株有效果枝和花芽的分化数较少,而无效果枝和花芽分化数则较多. (2)根据棉花生育期、叶龄和果枝、花芽分化间的关系来预测产量的形成过程,并为棉花高产栽培提供理论依据.
The relationship between the leaf age and the fruiting branches and the flower bud differentiation and development was observed and studied at the different growth stages of one cotton and one jacket cotton from the seedling stage to the effective bud termination stage.The results showed that: (1) Compared with a hot cotton, The cotton bud differentiation stage later, the effective flower bud differentiation period is shorter, the number of effective fruiting branches and flower buds per plant less, but no effect of branches and flower bud differentiation number are more. (2) According to the cotton growth period, leaf age and Fruiting branch, the relationship between flower bud differentiation to predict the formation of yield, and provide a theoretical basis for high-yielding cotton cultivation.
