| 摘 要： | 为探究茉莉酸甲酯(methyl jasmonate,MeJA)对采后猕猴桃品质和抗氧化酶活性的影响,将采后‘金魁’猕猴桃果实用0. 1 mmol/L MeJA进行熏蒸处理,测定在常温(25±1)℃贮藏过程中果实品质和抗氧化酶活性的变化。结果表明,与对照相比,经MeJA处理的猕猴桃果实腐烂率、失重率显著降低26. 09%和20. 79%,使可溶性固形物(TSS)含量维持在较高水平,延缓可滴定酸(TA)的降解速率,抑制呼吸强度的上升;同时促进总酚含量的积累与合成,降低丙二醛(MDA)含量;过氧化氢酶(CAT)、过氧化物酶(POD)以及超氧化物歧化酶(SOD)活性最大值依次显著高于对照34. 73%、30. 09%和2. 70%,而对维生素C(Vc)、总糖(TSC)含量以及硬度的影响并不明显。综上所述,MeJA预处理能够有效保持‘金魁’猕猴桃果实品质,延长猕猴桃果实贮藏期。
