| 摘 要： | 以‘金魁’猕猴桃果实为试验材料,研究茉莉酸甲酯(methyl jasmonate,MeJA)调控防御酶活性抗猕猴桃采后软腐病的效应。测定了MeJA对猕猴桃软腐病病斑直径、软腐病菌Botryosphaeria dothidea抑菌作用及超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、过氧化物酶(POD)、抗坏血酸过氧化物酶(APX)和多酚氧化酶(PPO)等防御酶活性的影响。结果表明:在0.001～10 mmol/L浓度范围内,MeJA对猕猴桃软腐病菌B.dothidea的抑制作用随浓度升高而增强;MeJA对猕猴桃果实最佳诱导浓度和熏蒸时间分别为0.1 mmol/L和24 h,其诱导效果分别为26.01%和26.85%;猕猴桃果实经0.1 mmol/L MeJA熏蒸处理24 h后,SOD、POD、CAT、APX和PPO活性提高,其中SOD和POD活性分别较对照增加33.85%和61.61%,差异达显著水平(P<0.05)。以上结果暗示MeJA诱导猕猴桃果实抗采后软腐病可能与其提高防御酶活性有关。
