冬小麦籽粒灌浆期旗叶枯尖与根系特征的关联研究
The relationship between flag leaf withertip and root characteristics of winter wheat at filling stage
摘要
Abstract
Pot experiments with winter wheat were carried out to investigate the relationships of flag leaf withertip of wheat cultivars at filling stage to root activity,dry and fresh weights of roots per plant,and root/ shoot ratio. The results showed that the flag leafs chlorophyll content of wheat cultivars with flag leaf withertip was lower than that of normal wheat cultivars,and there was a close relation between occurrence of flag leaf withertip and root characteristics of wheat cultivars at later growth stage. The wheat cultivars with flag leaf withertip were relatively low in root activity at later growth stage,and the fresh root weight,dry root weight and root/shoot ratio of the 2 cultivars with flag leaf withertip were obviously lower than those of the tested 4 cultivars without flag leaf withertip.关键词
