摘要
以秦光油桃为材料,研究了1 MCP 处理对外源乙烯诱导的果实硬度、呼吸、乙烯、EFE活性的影响。结果表明,1 MCP处理可抑制外源乙烯诱导的果实硬度下降,呼吸速率和乙烯合成的增加,推迟乙烯诱导果实呼吸峰和乙烯峰的出现,并降低了乙烯峰值,但提高了呼吸峰值,且对外源乙烯诱导的EFE活性无明显影响。
Qinguang” nectarine was used to investigate the effects of 1-MCP (an inhibitor of ethylene) on fruit firmness, (respiration), ethylene production and activity of ACC oxidase induced by exogenous ethylene during fruit ripening. The results showed that 1-MCP could restrain the loss of fruit firmness, the increase of respiration rates and ethylene production rates induced by exogenous ethylene. It postponed the appearing time of respiration and ethylene production, degraded the height of ethylene peak, but increased the height of respiration peak induced by exogenous ethylene. 1-MCP didn’t inhibit the increase of the activity of ACC oxidase induced by exogenous ethylene.
