| 摘 要： | 初步研究了采后38℃ 96 h热空气处理对红富士苹果青霉病的抑制效果, 并测定了与抗病相关酶的活性。结果表明: 直接接种病原菌后冷藏8周的苹果病害发病率和病斑面积达到78.33%和20.83 cm2 ,与之相比, 热处理后再接种病原菌的果实发病率和病斑面积分别下降了16.67%和22.8%。在贮藏过程中,热处理组果实苯丙氨酸解氨酶( PAL) 和过氧化物酶( POD) 活性、木质素和总酚含量在贮藏中后期均高于对照组, 可见热处理提高了红富士苹果果实的诱导抗病力。

| Abstract: | In this paper, the inhibitory effects of hot air treatment (38℃, 96 h) on the blue mold rot ofapp les fruit (Malus domestica Borkh. ‘Red Fuji’) were investigated. The activities of related enzymes of disease resistance were also determined. The decay incidence and lesion area was 78.33% and 20.83 cm2 respectively on the app les only inoculated with Penicillium expansum spores after storage at 2℃ for 8 weeks.Compared with the control apples, the decay incidence and lesion area was reduced by 16.67% and 22.8%respectively on the heat-treated app les before inoculation. Further research found that, the phenylalanine ammonium lyase ( PAL) and peroxidase ( POD) activity, the content of lignin and total phenomena of treated app leswere higher than controls at the later period of storage, which imp lied that heat treatment enhanced the induced disease resistance of the app les to P. expansum. |
