【摘要】 1-MCP是目前最具市场潜力的园艺产品采后保鲜剂。用浓度为250nL·L-1、500nL·L-1和 1000n L·L-1的1-MCP处理金冠果实,结果表明,通过降低果实的呼吸强度、减少果实硬度和可滴定酸的损失,1-MCP处理能明显延迟果实的后熟与衰老。同时发现,1-MCP处理抑制了果实中淀粉和果皮叶绿素的转化和分解。试验证明,1-MCP能够显著地延长金冠果实货架期,提高果实的贮藏质量。更多还原

【Abstract】 1 - MCP, an ethylene inhibitor as the most promising fresh keeping agent of horticultural products, was applied to ’ Golden Delicious apple fruits after harvest at ambient temperature. 1 - MCP gas concentrations used were 250nL·L-1, 500nL·L-1 and 1000nL·L-1 generated from measured amount of EthylBloc (tm) (0.14%) powder. The results indicated that 1 - MCP dramatically delayed fruit ripening and senescence by reducing respiration rate, decreased the loss of fruit firmness and maintained higher fruit acidity. Chlorophyll in the fruit skin and starch in fruit were also inhibited by application of 1 -MCP. The results implied that 1 - MCP can prolong the shelf life and maintain the quality of ’ Golden Delicious apples after harvest and improve storage quality.更多还原
