外源NO对采后芒果果实低温胁迫后H2 O2代谢的影响
Effect of Exogenous NO on H2 O2 Metabolism in Postharvest Mango Fruit under Low Temperature Stress
摘要
Abstract
Nitric oxide (NO) is an important signal molecule in plants. In order to discuss the effect of NO on H2 O2 level and metabolism in postharvest mango fruit under low temperature stress, 0. 08 mmol/L NO donor SNP and 30 μL/L NO gas were used to treat green mango fruit before cold storage. H2 O2 content and the activities of superoxide dismutase (SOD), catalase (CAT), peroxidase(POD) and ascorbate peroxidase (APX) were measured 12 d after cold storage at 3℃. The results showed that both SNP and NO gas treatments had significantly reduced H2 O2 level in postharvest mango fruit pericarp, and increased the activities of SOD, CAT and POD. The effect of SNP was more significant than NO gas. The main effect site of exogenous NO was pericarp.关键词
