摘要
研究了万寿菊杀菌素水乳剂对西瓜枯萎病菌菌丝生长的影响和对西瓜幼苗保护酶的作用。结果表明,万寿菊杀菌素水乳剂对西瓜枯萎病菌的菌丝生长有明显的抑制作用,当质量浓度为1μg/mL时已完全抑制病菌菌丝生长。同时,经对西瓜幼苗叶的酶活性测定和过氧化物同工酶电泳分析的结果表明,该万寿菊杀菌素水乳剂能使西瓜保护酶———超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和过氧化物酶(POD)活性提高,减轻西瓜枯萎病菌对西瓜幼苗的毒害作用。
In the article the influence of the mycelium growth of watermelon wilt disease and the role of protective enzymes in watermelon seedlings from marigold spinosad water emulsion were studied.The results showed that it could restrain the mycelial growth of watermelon wilt disease obviously,and the growth in 1 μg/mL marigold spinosad water emulsion was completely stopped.The results of enzymic activity assay on watermelon seedlings＇ leaves and electrophoresis analyse of peroxide isozyme demonstrated that marigold spinosad water emulsion could enhance the activity of protective enzymes-superoxide dismutase（SOD）,catalase（CAT）,Peroxidase（SOD）,reduced the harm to watermelon seedlings by watermelon wilt disease.
