| 摘 要： | 以亚种间杂交稻为材料 ,研究了在不同生育期及不同处理条件下其根系伤流强度的变化 ,认为根系伤流量的变化可以很好地反映稻株根系活力在品种及生育进程上的差异 ,并指出亚种间杂交稻根系活力的衰退主要发生在灌浆中后期

| 关 键 词： | 亚种间杂交稻 根系伤流液 根系活力 灌浆期 |

| Abstract: | We study changes of root exudate of inter\|subspecific hybrid rice with different treatments at different growth stages. The results show that changes of root exudates are a good index to reflect the differences of root system activities on varieties and growth stages. Furthermore, we supposed that decrement of root system activities of inter-subspecific hybrid rice mainly happened at grain ripening stage. |
