The results showed that 22.5μL/L of clove leaf oil had the best preservation effect on peach. After 35 days of stock, the sound fruit rate was 94%, 46.9% higher than compared group. The rotten index and the browning index were 94.1% and 85.2% lower than the control, respectivly, and the treatment could remarkablely reduce the respiration rate and ethylene release, and postponed ethylene release peak and respiration peak 5 and 10d, respectively in comparison with CK, it also delayed the drop of firmness and contents of titrable acids of the peach. When stored for 35d, firmness of control group and 22.5μL/L of clove leaf oil were decreased 60% and 34% compared with initial storage, and the activities of SOD, CAT and POD were enhanced, but the contents of SSC had no obvious difference with control.

结果表明，与对照相比，22.5μL/L丁香叶油处理对桃果实的防腐保鲜效果最好，贮藏35d时好果率为94%，比对照提高了46.9%，腐烂指数和褐变指数分别比对照低94.1%和85.2%；丁香叶油处理可以有效降低桃果实的呼吸强度和乙烯释放量，呼吸强度高峰和乙烯释放量高峰分别推迟5和10d，延缓了果实硬度和可滴定酸含量下降的速度；贮藏35d时对照和22.5μL/L丁香叶油处理果实硬度分别比贮藏初期降低了60%和34%；丁香叶油处理提高了超氧化物歧化酶、过氧化氢酶、过氧化物酶3种膜脂过氧化物酶的活性，但可溶性固形物含量与对照相比无明显差异。
