中文摘要: 为研究1-甲基环丙烯（1-MCP）熏蒸处理对油菜贮藏品质的影响，本试验采用不同浓度（2、4、8 μL/L）1-MCP熏蒸处理油菜，然后转入4℃下贮藏，测定其生理生化变化。结果表明：2 μL/L 1-MCP处理对油菜贮藏起到较好的保鲜效果，1-MCP处理可有效维持油菜的贮藏品质，抑制色差a*和b*值的升高，延缓叶片褪绿转黄，维持叶绿素和维生素C含量，抑制丙二醛（MDA）含量的积累，同时增强了抗氧化酶（APX、POD和CAT）酶活性，减轻了活性氧代谢对组织的损伤。因此，2 μL/L 1-MCP处理可有效保持油菜的贮藏品质。

Abstract:To study the effect of 1-methylcyclopropene（1-MCP）treatment on storage quality of pak choy，different concentrations（2，4，8 μL/L）1-MCP were used to treat pak choy，then stored at 4℃，the changes of physiological and biochemical were measured.The results showed that 2 μL/L 1-MCP treatment had good preservation on pak choy storage.The storage quality was maintained，a*value and b*value were suppressed，and the degradation of chlorophyll and yellowing of leaf were delayed，meanwhile the content of chlorophyll and vitamin C were maintained by the 1-MCP treatment.The accumulation of MDA content was inhibited and the activities of antioxidant enzymes（APX，POD，CAT）were enhanced during the storage，which relaxed the damage by reactive oxygen free radicals.Thus，2 μL/L 1-MCP treatment was effectively maintained the storage quality of pak choy.
