摘要
以"白玉"、"冠玉"枇杷为试材,研究了低温贮藏和1μL/L、2μL/L、5μL/L、10μL/L四种不同浓度1-甲基环丙烯(1-MCP)处理对枇杷采后贮藏品质特性的影响,定期对2种不同品种枇杷的Vc含量、可滴定酸含量、可溶性糖含量以及POD酶活性变化情况进行测定。结果表明:1-MCP处理和低温贮藏相结合,能够延缓枇杷的后熟和衰老过程,不同品种枇杷对不同浓度的1-MCP响应情况是不同。总体而言,1-MCP对枇杷果实中的可滴定酸含量以及Vc含量的保持效果很好,对果实中的可溶性糖含量和POD酶活性无特别明显的影响。
＂Baiyu＂, ＂Guanyu＂loquats were used to investigate the effects of 1 ix L/L, 2 ix L/L,5 ix L/L and 10 ix L/L 1-methlcyclo- propene on the quality of the storage fruit at the low temperature. The titratable acid content, total sugar content, vitamin C content and the activities of peroxidase （POD） were explored in postharvest loquats treated with 1-MCP at various dosages during the storage at 6 ℃. The results indicated that the combination of 1-methylcyclopropene treatment and storage at the low temperature could distinctly decay the after ripening and senescence, and different kinds of loquats appeared different effects of 1-MCP. All in all, the treatment of 1-MCP can obvi- ously keep the titratable acid content of loquat and Vc content, but the effects were unconspicuous in the contents of soluble sugar and the activities of peroxidase （POD）.
