摘要:

目的:探讨冷藏、冰温贮藏、1-甲基环丙烯(1-methylcyclopropene,1-MCP)处理结合冰温贮藏对采后柿果硬度和软化相关物质代谢的影响。结果:与冷藏处理相比,冰温贮藏有效抑制了乙烯生成,抑制了多聚半乳糖醛酸酶(PG)、纤维素酶(Cx)、淀粉酶活性的增加,抑制了可溶性果胶含量的升高,延缓了果肉硬度的降低,而1-MCP处理结合冰温贮藏对柿果实硬度的保持、抑制PG、Cx、淀粉酶活性升高的作用好于冰温单一贮藏,因此,1-MCP处理结合冰温贮藏是保持柿果实硬度较为适宜的贮藏方法。

Abstract:

This research was designed to discover the comparative effects of cold storage as well as controlled freezing
point storage (CFPS) alone and combined with 1-methylcyclopropene (1-MCP) treatment on fruit firmness and
metabolites related to fruit softening in Mopan persimmon. Results showed that in comparison with cold storage, CFPS
not only effectively reduced ethene production and delayed the losses of fruit firmness, but also significantly inhibited
the activities of polygalacturonase (PG), cellulase (Cx) and amylase, suppressed the increase in water soluble pectin
(WSP) and delayed softening. 1-MCP in combination with CFPS was more effective than single CFPS in maintaining
the firmness, and inhibiting the activities of PG, Cx and amylase, providing a more suitable way to maintain the
firmness of Mopan persimmon.

Key words: Mopan persimmon, 1-methylcyclopropene (1-MCP), controlled freezing point storage, firmness, softening
