| 摘 要： | 为探讨1-甲基环丙烯(1-MCP)对西葫芦采后生理生化指标的影响,试验设计了对照CK、5μL/L和10μL/L1-MCP在20℃下熏蒸20h,并在20℃下贮藏。结果表明,1-MCP处理可以显著抑制西葫芦采后呼吸强度,并延迟呼吸高峰的出现,延缓西葫芦果实中抗坏血酸和可溶性蛋白的降解,抑制细胞膜透性的升高,并使贮藏期间西葫芦果实内超氧化物歧化酶(SOD)和过氧化氢酶(CAT)维持较高水平。研究同时发现,10μL/L的1-MCP处理较5μL/L1-MCP处理效果好。

| Abstract: | In order to discuss the effect of 1-methylcyclopropene treatment on index of physiology and biochemistry of summer squash on postharvest,the experiments were made by three treatments:control,5 μL/L 1-MCP treatment,10 μL/L 1-MCP treatment.All the treatments were treated for 20 h at room temperature(20 ℃) followed by storage at 20 ℃.The results showed that 1-MCP treatment could restrain the respiration rate,postpone the appearing time of respiration peak,delay the decline of Vitamin C and protein content of summer squash.In addition,the raise of cell membrane permeability was inhabited,the SOD and CAT activities are preserved at a high level.At the same time,it was found that the effect of 10 μL/L content was the best. |
