| 摘 要： | 以"象牙"和"台农"芒果为试材,研究BTH处理对2个品种芒果果实中活性氧(O2.-和H2O2)及其抗氧化酶(SOD和CAT)的影响,以探讨BTH增强果实抗病性的机理。结果表明:整个贮藏过程中,经过BTH处理,2个品种芒果O2.-产生速率、H2O2含量都明显高于对照;同时诱导了SOD和CAT活性的上升,但CAT在贮藏后期受到抑制。"台农"果实中O2.-产生速率、SOD和CAT活性约是"象牙"果实2倍,H2O2含量也高于"象牙"果实。

| Abstract: | Nang klangwan and Tainong mango fruits were used as the experimental subjects to conduct BTH treatments.The effect of BTH treatment on the Active Oxygen and Anti-oxygenized Enzyme Activity in postharvest fruits was evaluated to explore the disease-resistance mechanisms of mango fruits from different varieties.Results indicated that the generate rate of superoxide radical(O2.-) and content of H2O2 were significiantly higher than CK in the Mango fruits from both varieties after being treated by BTH during storage.Meanwhile,the activities of superoxide dismutase (SOD) and catalase(CAT) were enhanced,but CAT was inhibited in the late storage.In addition,generate rate of O2.-,activities of SOD and CAT in Tainong mango were two times of those in Nang klangwan mango fruits during storage,content of H2O2 was also higher than that of Nang klangwan mango. |
