主 题：1-Methylcyclopropene Anxi persimmon fruit decay disease resistance lignin total phenolics
摘 要：Objectives:The purpose of this work was to evaluate the potential application of papers containing 1-methylcyclopropene(1-MCP)postharvest treatment for suppressing fruit decay of fresh Anxi persimmons and its possible *** and methods:Anxi persimmon fruit were treated with papers containing 1-MCP at the dosage of 1.35μL/L and stored at(25±1)℃and 85 per cent relative humidity for 35 *** storage,the fruit decay rate and lignin content were evaluated,and the content of total phenolics,the activities of phenylalanine ammonia lyase(PAL),polyphenol oxidase(PPO),peroxidase(POD),chitinase(CHI),and p-1,3-glucanase(GLU)were determined by ***:The 1-MCP-treated persimmons displayed a lower fruit decay rate,but higher contents of lignin and total phenolics,higher activities of PAL,PPO,POD,CHI,and ***:The treatment with 1-MCP could inhibit the fruit decay of postharvest Anxi persimmons,which might be because 1-MCP enhanced fruit disease resistance by increasing the activities of disease resistance-associated enzymes and retaining higher contents of disease resistance-related substances in postharvest fresh Anxi *** findings indicate that papers containing 1-MCP at the dosage of 1.35μL/L have potential application in suppressing fruit decay and extending storage life of postharvest fresh Anxi persimmons.
