| Abstract: |
| Effect of water stress and re-watering after water stress on root conformation,activity and accumulation of dry matter of rice root were studied using pot cultivation.The results showed that accumulation of dry matter of rice root,root/shoot ratio,root activity and the number of root per seedling decreased,while mean root length increased greatly compared with full irrigation.After re-watering,accumulation of dry matter and number of root per seeding,root length and root activity increased greatly compared with full irrigation.It suggests that re-watering after water stress in tillering stage has over-compensatory effects on root conformation and absorbing activity. |
