1-MCP对东方百合开放与衰老的影响

以东方系列百合（Lilium spp.）‘西伯利亚’品种为材料,研究了1-甲基环丙烯（1-MCP）对百合切花质膜透性、乙烯释放量、丙二醛含量、可溶性蛋白质含量等生理指标的影响。结果表明：1-MCP可延缓百合切花花瓣质膜相对透性的增加,延长百合切花瓶插寿命;降低百合花瓣乙烯释放量,推迟乙烯峰的出现;降低百合花瓣丙二醛含量,对可溶性蛋白含量的变化无明显影响。本研究结果说明1-MCP对东方百合切花的保鲜有一定效果,确定了1-MCP处理东方百合的最佳使用浓度为0.01μL/L。

Effects of 1-MCP on Florescence and Senescence of Oriental Lily

The oriental lily 'Siberia' was used to study the effects of 1-methyleyelopropene 1 -MCP on membrane permeability, ethylene, malondialdehyde and soluble protein of lily. The results showed that the development and senescence of cut flowers were delayed,the vase life of lily was lengthened and the appearing time of ethylene peak was postponed after treatment with 1-MCP. The cytomembrane permeability, ethylene peak and malondialdehyde content of plasma membranes could be reduced with the treatment of 1-MCP, but had no effects on soluble protein content of oriental lily. The results also showed that the 1-MCP had some effects for fresh-keeping of lily. The optimum concentration of 1-MCP was 0.01 μL/L. Meanwhile, the most effective concentration treatment can offer help for the 1 -MCP application in lily postharvest and enhance lily cut flowers quality and economic efficiency.
