摘要
摘要研究了芋头(Colocasia esculenta var. antiquorum)耐、敏感品种健康和患病叶片中过氧化物酶、多酚氧化酶、总酚和总蛋白含量对疫霉病的特异性活性。与敏感品种相比，耐药品种的总酚和总蛋白质含量分别增加了100%和81%。耐药品种过氧化物酶比活性高于敏感品种，多酚氧化酶比活性低于敏感品种。调整决定系数(R2)为0.99时，得到多元回归方程，表明耐受性与所测各组分均相关。
Peroxidase, Polyphenoloxidase, Total Phenol and Protein Content in Leaf Tissues of Colocasia esculenta var. antiquorum and Their Relationship to Phytophthora Leaf Blight Disease
ABSTRACT Specific activities of peroxidase, polyphenoloxidase, total phenol and total protein content in healthy and diseased leaves of tolerant and susceptible cultivars of Taro (Colocasia esculenta var. antiquorum) to Phytophthora leaf blight disease were studied. Tolerant cultivars of Colocasia had 100% and 81% increase of total phenol and protein, respectively, when compared to susceptible cultivars. The specific activity of peroxidase remained higher while that of polyphenoloxidase remained lower in tolerant cultivars as compared to susceptible cultivars. Adjusting coefficient of determination (R2) at 0.99, the multiple regression equation was derived, which indicated that tolerance was related to all of the components measured.
