摘　　要：目的概述不同植物激素及生长调节剂作用机理,探讨其在采后蓝莓果实衰老过程中的作用,展望如何延长蓝莓果实的贮藏期。方法介绍植物激素乙烯、水杨酸(SA)、茉莉酸甲酯(MeJA)、脱落酸(ABA)及植物生长调节剂1-甲基环丙烯(1-MCP)的作用,及其对采后蓝莓果实衰老进程的影响和在保鲜领域的应用。结果由于蓝莓果实成熟于高温多雨的季节,且其果实含水率高、果皮薄,导致其贮藏性差,采后极易发生软化,最终衰老腐烂。近年来的研究表明除细胞壁降解酶类之外,内源激素含量也能调控果实的成熟及衰老,而施用不同植物激素及生长调节剂则是延缓果实衰老的有效措施。结论高浓度外源乙烯及脱落酸的施用会加速果实软化及衰老现象的发生,适当浓度的乙烯、1-MCP、SA、MeJA处理可以延缓果蔬采后衰老所带来的腐败变质进程。The work aims to summarize the mechanism of action of different plant hormones and growth regulators, discuss their role in the senescence process of postharvest blueberry fruit, and predict how to prolong the storage period of blueberry fruits. The roles of plant hormones such as ethylene, salicylic acid(SA), methyl jasmonate(MeJA) and abscisic acid(ABA) and plant growth regulator 1-methylcyclopropene(1-MCP), and their effects on the senescence process of postharvest blueberry fruit and application in preservation were introduced. The blueberry fruit, matured in the season of high temperature and rain, with high fruit water content and thin pericarp, resulted in poor storability, easy softening after harvest, and eventually aging and rotting. Studies in recent years had shown that, in addition to cell wall degradation enzymes, the content of endogenous hormones could also regulate fruit ripening and senescence, and the application of different plant hormones and growth regulators was an effective measure to delay fruit senescence. The application of high-concentration exogenous ethylene and abscisic acid can accelerate the process of fruit softening and senescence. The treatment with ethylene, 1-MCP, SA and MeJA of proper concentration can delay the spoilage and deterioration caused by postharvest senescence of fruits and vegetables.
