| 摘 要： | 为了研究紧凑型小麦冠层叶片对籽粒的影响,选用紧凑型小麦高优503、郑麦004、济麦20为材料,对小麦冠层叶片的叶绿素含量、光合速率及不同剪叶处理籽粒灌浆期的千粒重进行测定。结果表明:紧凑型小麦冠层叶片叶绿素含量表现为旗叶、倒2叶>倒3叶;光合速率表现为旗叶>倒2叶>倒3叶;旗叶对强势粒和弱势粒的影响最大,冠层叶片对强势粒的影响是旗叶、倒3叶>倒2叶,而对于弱势粒则是旗叶>倒3叶、倒2叶。

| Abstract: | In order to study the effects of different functional leaves on the grain of compact-type wheat,the photosynthesis efficiency,chlorophyll content of different functional leaves,and 1000-grain weight in different leaf-cutting treatments of compact-type wheat varieties Gaoyou 503,Zhengmai 004 and Jimai 20 were measured.The results were as follows: the chlorophyll content in the flag leaf and backward second leaf was more than that in the backward third leaf;the photosynthesis efficiency revealed the following... |
