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,减小叶绿素的分解,但低浓度的1-MCP处理增加了苦痘病的发生率。

摘  要:
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稬_(-1), 500 nL?L_(-1) and 1000 nL稬_(-1) generated from measured amount of Ethylbloc~(TM)(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.
