Title: Effects of Drought Stress on Photosynthetic Characteristics and Active Oxygen Metabolism of Cucumber Seedlings
Abstract: To ascertain the effect of drought stress on photosynthesis and active oxygen metabolism of cucumber and correlation between them,different drought stress were simulated by weighting soil to ease drought stress,the physiological indices of photosynthesis,active oxygen metabolism and correlation analysis were measured.The results showed that net photosynthesis of cucumber declined under drought stress,increasing active oxygen metabolism,the activity of SOD,POD and APX were inhibited.O2-generating rate and MDA were negative correlation with net photosynthesis rate.It indicated that O2-accumulating more had led to lipid peroxidation increased and declining net photosynthesis rate.
