Research on Compensatory Effects of Water-recovery on Rice at Tillering Stage

摘要：

Effects of water stress and recovery after water stress on rice at tillering stage were studied.Results showed that the plant height and leaf area increases,and they approached even exceeded the control.After rewatering,the content of chlorophyll approach or even exceed that of control.The photosynthetic rate (Pn) increases and was higher than control.This implies that the rewatering after water stress has over compensatory effects on Pn,over a long time.The accumulation of dry matter of root,the number of root per seedling and the root activity were all increased after water recovery.It means that it has a compensatory effect on rice root after plants were rewatered.
