Effect of Water Stress on Stomatal Density,Length,Width and Net Photosynthetic Rate in Rice Leaves

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.
