Effects of Stripe Rust on Chlorophyll Fluorescence and Photosynthesis of Winter Wheat

WANG Bei-hong,HUANG Mu-yi,MA Zhi-hong, WANG Ji-hua (National Engineering Research Center for Information Technology in Agriculture,Beijing 100089 ,China)  
Several physiological indicatrixes of healthy and diseased last expanding leaves were measured after inoculation a week later. With the farther infecting of stripe rust,water content of leaves,relative content of chlorophyll, the efficiency of primary light energy conversion and the potential activities of photo system Ⅱ decrease . The correlation analysis between net photosynthesis rate and severity showed that there was significantly negative correlation between net photosynthesis rate and severity. What's more,the correlation analysis between transpiration rate and severity showed that there was significantly negative correlation between transpiration rate and severity.
