【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 -1 and 1000 nL·L -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.更多还原
