| 摘 要： | 以不同基因型棉花品种（常规棉新陆早13号、杂交棉标杂A1）为材料，在皮棉产量2500 kg以上的膜下滴灌高产条件下，于花铃期分别进行剪叶、疏蕾处理，研究了源库关系改变对叶片光合速率、14C同化物运转分配及产量的影响。结果表明，去1/4叶后，新陆早13号剩余叶片光合速率（Pn）显著增加，14C同化物输出率及在棉铃中的分配率提高，产量和纤维品质与对照（CK）无明显差异；疏1/4蕾铃后，标杂A1叶片Pn和棉株光合物质累积未受到影响，但加速了同化物向棉铃的运转速率，增强了棉铃对茎叶和根系中同化物的再调运能力，产量高于CK。因此，依据不同品种对源库关系改变的响应，通过协调关键栽培技术调控源库关系，进而调节光合产物运转及分配的方向和速率，对实现新疆棉花超高产、稳产具有重要意义。

| Abstract: | Selected cotton cultivars of different genotypes as experimental materials,the effects of leaf-cutting and bud-thinning on photosynthetic rate,partitioning of 14C-assimilate and yield during flowering and boll-setting stage in high-yield cotton were studied.The results indicated that when leaves were cutted 1/4 at anthesis,the photosyntetic rate and the percentage 14C-assimilate of export and partitioning in boll of Xinluzao 13 at full bolling and boll opening stages increased.Conclusively,seed cotton yield... |
