摘要
研究了1-甲基环丙烯(1-MCP)对九龙金枣采后生理及贮藏品质的影响.将成熟度为果面3/4红的九龙金枣用1-MCP熏蒸处理,置于-1～0℃冷库中贮藏,定期测定呼吸强度、失重率、果实硬度、还原糖含量、可滴定酸含量、抗坏血酸(Vc)含量、叶绿素含量和多聚半乳糖醛酸酶(PG)、过氧化物酶(POD)、过氧化氢酶(CAT)、多酚氧化酶(PPO)的活性.结果表明:1-MCP具有抑制九龙金枣PG、PPO、POD活性和增强CAT活性的作用,使叶绿素、抗坏血酸以及果实硬度得以较好地保持,贮藏100d好果率90%.
Effects of treatment with 1-methylcyclopropene （1-MCP） on post-harvest physiologyand storage quality of Jiulong golden jujube were studied. Three-quarters red of Jiulong golden jujube surface were fumigation with 1-MCP and placed in cold storage at --1-0℃. Respiration, weight loss, hardness, reducing sugar, titratable acid, ascorbic acid （Vc）, chlorophyll content as well as poly--galaeturonic acid enzyme（PG）, peroxidase （POD）, catalase （CAT）, polyphenol oxidase （PPO） activity were determined regularly. Results showed that the polygalacturonic acid enzyme （PG）, polyphenol oxidase （PPO） and peroxidase （POD） activity were significantly inhibited by 1-MCP treatment in Jiulong golden jujube, while the peroxide catalase （CAT） activity was enhanced; 1-MCP treatment maintained better of chlorophyll, and fruit firmness of Jiulong golden jujube, the accepted fruit percentage ascorbic being acid content 90% after 100days of storage.
