摘要: 以南果梨果实为材料,研究1 μL/L 1-甲基环丙烯(1-methylcyclopropene,1-MCP)处理对其采后常温 (23±1)℃贮藏过程中软化的影响。结果表明:与对照组相比,1-MCP处理能推迟乙烯高峰的出现并降低其峰 值,减缓果实硬度的下降与丙二醛含量的上升,有效抑制纤维素酶、多聚半乳糖醛酸酶、果胶甲酯酶及淀粉酶活力 的增加,减缓可溶性果胶质量分数的增加,同时延缓纤维素、原果胶及淀粉质量分数的下降。因此,1-MCP处理能 有效减缓采后南果梨果实的软化进程,延长其贮藏时间。

Abstract: The effect of 1 μL/L 1-methylcyclopropene (1-MCP) on the softening of Nanguo pear fruits during postharvest storage at room temperature (23 ± 1) ℃ was studied. The results showed that 1-MCP treatment delayed the occurrence of ethylene peak and decreased its peak value, slowed down the decrease in fruit firmness and the increase in malondialdehyde content, significantly inhibited the activities of cellulase, polygalacturonase, pectin methyl esterase and amylase, retarded the increase in soluble pectin content, and simultaneously delayed the decrease in cellulose, protopectin and starch contents. Therefore, 1-MCP treatment could effectively slow down the softening process of postharvest Nanguo pear fruits and prolong its storage life.

Key words: Nanguo pear, 1-methylcyclopropene, softening, postharvest storage
