摘要: 试验结果表明, 1-MCP (1 - 甲基环丙烯) 处理可以明显降低‘乔纳金’苹果果实的呼吸强度,延迟呼吸高峰的出现, 明显减缓硬度和酸度的下降, 减少叶绿素的分解, 但低浓度的1-MCP 处理增加了苦痘病的发生率。

Abstract: 1-MCP , an ethylene inhibitor as the most promising fresh keeping agent of horticultural products,was applied to‘Jonagold’apple fruits after harvest at ambient temperature. 1-MCP gas concentrations used were 250 nL·L -1, 500 nL·L -1and 1000 nL·L -1 generated from measured amount of EthylblocTM (0. 14 %) powder.The results indicated that 1-MCP delayed fruit ripening and senescence by decreasing respiration rate , delayed the time of climacteric phase of respiration. It decreased the loss of fruit firmness and acidity dramatically. Decomposition of chlorophyll in the fruit skin was inhibited by application of 1-MCP. The results also implied that 1-MCP treatments increased the incidence of bitter pit after harvest and its reason was unclear.
