摘要: 试验主要研究了在2℃下,小袋包装气调(MAP)和6-苄基腺嘌呤(6-BA)处理对黄花菜采后生理生化指标的影响。在试验过程中测定了超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)的活性、超氧自由基的生成速率以及丙二醛(MDA)的含量。试验结果表明:小袋包装气调和6-BA处理都能提高黄花菜中的超氧化物歧化酶的活性,同时能抑制超氧自由基、丙二醛的生成、抑制过氧化物酶和过氧化氢酶活性的提高,从而延缓采后黄花菜的衰老。6-BA处理比单用小袋包装气调效果要好。

Abstract: Effects of modified atmosphere packaging and 6-BA treatment on physiology of post-harvesting of Day-lily flowerwere studied at 2 ℃. The activity of superoxide dismutase, peroxidase and catalase, the producing speed of superoxide freeradical and the contents of malondialdehyde was tested in the experiment. The results proved that both treatments not onlycould improve the activity of superoxide dismutase and inhibit the activity of peroxidase and catalase, the producing velocity ofsuperoxide free radical and yielding of malondialdehyde but also postpone the senescence of Day-lily flower. The effect ofcombining 6-BA treatment with modified atmosphere packaging treatment was better than the latter alone.
