| 摘 要： | 以4个对低磷反应不同的典型水稻品种(系)为材料,对其在低磷胁迫下根系有机酸分泌这一根系生理特性进行了比较研究。结果表明,低磷胁迫能促使水稻根系分泌更多的有机酸,这在耐低磷品种中表现尤为明显。

| Abstract: | The physiological characteristic of organic acid secretion of roots was examined in material of four typical rice varieties with different reaction under the stress of low phosphorus. The results indicated that the stress of low phosphorus promoted rice roots to secrete more organic acid, which was displayed more manifestly in the low phosphorus-tolerant varieties. |

| Keywords: | Rice Stress of low phosphorus Root Organic acid secretion |
