Abstract

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.
