| 摘 要： | 以番茄品种‘百利’为试材, 研究了NO处理对其采后活性氧代谢的影响。结果表明: NO处理可推迟果实呼吸和乙烯高峰的出现, 抑制O·2 和H2O2 的累积, 保持了贮藏后期SOD、CAT、POD、APX 较高的活性以及GSH和AsA含量的较高水平, 延缓了MDA含量和膜相对透性的升高, 降低膜脂过氧化程度, 延缓了果实衰老。

| Abstract: | Experiments were conducted to study the effects of nitric oxide (NO) on active oxygen metabolism of postharvested‘Baili’tomato. The results showed that the application of NO delayed the respiration and ethylene peaks, inhibited the O·2 and H2O2 accumulation, maintained a higher level of the activities of SOD, CAT, POD, APX and the content of GSH and AsA at the late stage of fruit storage during active oxygen metabolism, slowed down the increase of MDA content and the relative membrane permeability, reduced the preoxide action of membrane lip ids, and postphoned the fruit senescence. |
