盐胁迫对玉米幼苗叶片光合荧光和抗氧化酶活性的影响
Effects on Photosynthesis in Leaves of Maize Seedlings and Antioxidant Enzymes Under Salt Stress
摘要
Abstract
Using maize(B73)seedlings as experimental materials,the photosynthetic efficiency and activities of SOD,POD and CAT of leaves were investigated under salt stress. The results showed that the low concentration of NaCl(100 mmol/L)had little impact on the photosynthetic efficiency of maize seedling leaves,but high concentrations of NaCl stress(200 mmol/L or more)could significantly affect on the photosynthetic efficiency. At the same time,the activity of antioxidant enzymes displayed a synthetic positively correlation. However,in response to high concentration of NaCl stress,the antioxidant enzyme system(SOD,POD and CAT)activity showed a decreasing trend after the first rise.关键词
