| 摘 要： | 为确定1-MCP对蕨菜采后生理特性的影响,分别采用250、750、1000和1250 nL·L-11-MCP(l-甲基环丙烯)40℃下熏蒸处理新鲜蕨菜24 h,于(5±1)℃条件下贮藏.研究不同浓度1-MCP对蕨菜储藏过程中失重率、呼吸强度、乙烯含量、乙醇含量、SOD活性和MDA含量的影响.结果表明,与对照组相比,1-MCP能够有效阻止水分流失,降低失重率,减少乙烯生成量,推迟乙烯峰值出现,抑制SOD活性下降,降低活性氧对蕨菜机体的伤害,减少MDA的积累,降低膜质的过氧化;1000 nL·L-11-MCP处理比其他三组处理更有利于蕨菜采后贮藏期间的品质保持(P<0.05).

| Abstract: | In order to study the influence of 1-MCP on Pteridium aquilinum post-harvest physiology character,different concentrations(250,750,1 000 and 1 250 nL · L-1) of 1-MCP(methylcyclopropene) were used to fumigate fresh Pteridium aquilinum,and they were fumigated for 24 h,at 40 ℃.And then were stored at(5±1) ℃.Research on the weight-loss ratio,breath strength,ethylene content,ethanol content,SOD activity,and MDA content of Pteridium aquilinum,was treated at different concentrations of 1-MCP.The results showed that comparing with the control group,1-MCP could effectively restrain moisture loss,reduce weight-loss ratio,lower ethylene production,delay the ethylene peak value appearing,inhibit SOD value decling;lower active oxygen damage,reduce MDA accumulation and membrane peroxidation.1 000 nL·L-1 1-MCP treatment was more advantageous than the other three groups during the storage period. |
