叶绿酸铁对硝酸盐胁迫下黄瓜幼苗渗透调节物质及抗氧化酶活性的影响
Effect of Chlorophyllin-iron on Osmoregulation Substance and Activities of Antioxidant Enzymes of Cucumber Seedling under Nitrate Stress
摘要
Abstract
A solution culture experiment was conducted to study the effect of exogenous spraying 10 mg·L-1 chlorophyllin-iron solution at cucumber (Cucumis sativus L.)seedling leaves on the plant growth,contents of proline,soluble sugar,MDA and activity of peroxidase under nitrate stress. The results showed that exogenous spraying chlorophyllin-iron solution at leaves could relieve the inhibition of nitrate on cucumber seedling growth, decrease the contents of proline,soluble sugar,MDA,and increase the activities of SOD,POD,CAT and APX. Eexogenous spraying chlorophyllin-iron could to certain extent reduce the accumulation of active oxygen in leaves under nitrate stress, restrain lipid peroxidation,and therefore relieve the damage of nitrate stress on cucumber seedlings.关键词
