| 摘 要： | 在水分胁迫下，水稻叶片的气孔密度明显增大，气孔的长、宽明显减小．气孔密度与气孔长度、宽度呈显著的负相关（r＝－0．90*，n＝7）、而气孔长度和宽度呈显著的正相关（r＝0．71*，n＝7）．在水分胁迫下，水稻叶片的净光合速率也显著下降，并表现出与气孔密度呈显著负相关（r＝－0．89，n＝7）．

| Abstract: | The experiment results showed that water stress made stomatal density of flag leaves increase andstomatal lengt, stomatal width decrease obviously. The stomatal density had a significant negative correlation with thestomatal length and the stomatal width. And the stomatal length was positively correlated with the stomatal width.The net Photosynthetic rate of flag leaves also decreased under the water stress and had a significant negaivecorrelation with stomatal density. |

| Keywords: | rice water stress stomatal density net photosynthetic rate |
