| 摘 要： | 以"美国8号"苹果为试材,研究了0℃贮藏条件下1-MCP处理对采后生理及相关酶活性的影响,结果表明:1μl/L 1-MCP处理可以显著抑制贮藏期间果实呼吸速率和乙烯释放量,延缓两者跃变高峰的出现;减缓果肉硬度和可滴定酸含量的下降,但对可溶性固形物含量无明显影响;同时保持贮藏后期SOD、POD、CAT的较高活性,从而降低膜脂过氧化程度,延缓果实衰老.

| Abstract: | Experiments were conducted to study the effect of 1-MCP on the postharvest physiology and related enzymatic activities of America No.8 Apple during the storage at 0 ℃.The results showed that 1-MCP significantly decreased the respiration rate and the ethylene production,delayed the respiration peak and the ethylene peak.1-MCP decreased the loss of the fruit firmness and acidity,but had no effect on the total soluble solids.In the meantime,it maintained a higher level of the activities of SOD,POD and CAT,reduced the peroxide action of the membrane lipids and postponed the fruit senescence. |
