| 摘 要： | 目的]超高产棉花器官同伸关系及棉铃空间分布特征,方法]选用了3个棉花品种,观察叶、蕾、花等器官同伸关系及棉铃空间分布.结果]初步得出超高产棉花果枝第1果节现蕾与主茎叶同伸关系为n+1.5～n-1.2;第一果节开花与主茎叶同伸关系为n+6.2～n+8.8(n为果枝同位主茎叶叶龄).结论]超高产常规品种棉花中下部内围铃所占比例高达90;以上,是超高产棉田棉铃的主体,上部铃占10;左右,上部及外围铃是实现超高产的潜力所在;超高产杂交棉中部铃比例占50;以上,下部铃和上部铃相当,叶枝成铃4.3;,外围铃的比例近40;,抓住上部及外围成铃是创高产的关键.

| Abstract: | Objective and Method]The aim of this text was mainly to study relations of together growth on organs and cotton bolls'spatial distribution of Super high-yielding cotton,Result]the relation of together growth of fruit branches'first cotton bud and the main stem leaves is n+1.5～n-1.2;The relation of together growth of fruit branches'first flower and the main stem leaves is n+6.2～n+8.8(n for the bit of main stem leaf with the same frui-bit). Conclusion]The proportion of the central-lower and interior part of bolls of super high-yielding conventional varieties cotton reached 90%,it is the main part of super high-yielding cotton bolls, The top part of bolls is about 10%,the top and external bolls is ultra-high yield potential; The proportion of the central bolls of super high-yielding hybrid'cotton is 50%, the proportion of the lower and top bolls is almost same, the bolls of foliage branch is 4.3%, The proportion of the external bolls is nearly 40%, the top and external bolls is the key of super high-yielding cotton. |
