| 摘 要： | 研究了小麦不同摘叶方式下 ,顶三叶与粒重的关系及不同类型品种之间的差异。结果表明 :顶三叶的摘除对粒重的影响大小排序为旗叶 >倒二叶 >倒三叶 ,整株摘叶对粒重的影响高于主茎摘叶 ;多蘖型小麦品种主茎摘叶后千粒重降低得少 ,与整株摘叶后千粒重降低率相比差距大 ,而少蘖类型降低得多 ,降低率相比差距小

| Abstract: | The relationship between the top three leaves and the grain weight,the differences among varieties under the different treatment of leaf picking were studied.The result showed that:the effect of picking top three leaves on the grain weight was in the following order:the effect of flag leaf>the effect of backward second leaf>the effect of the backward third leaf.The influence of picking whole plant leaves on grain weight was greater than that of picking leaves from the main stem leaves.The 100 grain weight of more tiller type varieties after pick main stem leaves was reduced much more than that of picking the whole plant leaves.This is contrary to the changes of less tiller type varieties. |
