摘要: [目的]探讨杂交棉高产形成的生理机制.[方法]在相同的密度和栽培条件下,研究常规棉花与不同品种杂交棉的性状表现.[结果]杂交棉新陆中31号和新杂1号与常规棉中棉43号相比,主茎功能叶叶绿素含量要高且保持时间长,从盛花到初絮间叶面积指数、干物质积累明显较高,分别高出10;和70;左右,且杂交棉成铃数多,单株成铃6~7个,成铃率高,单铃重大于5 g.[结论]棉铃在空间分布上,以中、下部果枝为主,而杂交棉第2果节的棉铃数与常规棉相比对产量的增加起了更关键的作用.

Abstract: [Objective and Method]The Xinluzhong31,Xinza1 and Zhongmian 43 were studied under same planting condition to investigate high yield physiological mechanism of hybrid cotton. [Result]The results showed that compared with Zhongmian 43,the chlorop hyll content of the stem from top to bottom of Xinluzhong31 and Xinza1 was high and kept long time.From blooming to initial boll opening ,the index of leaf area,accumulation of dry matter were obviously higher than that of Zhongmian 43 by 10; and 70;.The boll number of hybrid cotton were increased with 6-7 bolls per plant,the weight of single boll was more than 5 g.[Conclusion]The great part of botts were distributed on the middle and lower fruit node of the cotton plant.Therefore,the yield of hybrid cotton was much highter than that of common cotton.
