【摘要】 以秦光油桃为试材,研究了1-MCP处理对外源乙烯诱导果实软化的影响。结果表明,1-MCP处理可抑制外源乙烯诱导果实硬度的下降,将乙烯诱导果实的淀粉、纤维素和果胶类物质的降解延迟2天,对引起这些物质降解的相关酶类如淀粉酶、纤维素酶和多聚半乳糖醛酸酶(PG)等酶活性高峰的到来推迟2天,同时降低了多聚半乳糖醛酸酶(PG)活性高峰值。更多还原

【Abstract】 Qinguang nectarine was used to investigate the effects of 1-MCP (an inhibitor of ethylene) on softening of nectarine induced by exogenous ethylene during fruit ripening. The results showed that 1-MCP treatment could delay the loss of fruit firmness induced by exogenous ethylene and retarded the hydrolysis of starch, cellulose, alkaline-insoluble pectin and the increase of water-soluble pectin for 2 days.1-MCP can postpone the appearing time of the peak of amylase, cellulose and PG enzyme activities relating to fruit softening for 2 days, and reduced the peak of PG enzyme activities induced by exogenous ethylene.更多还原
