摘  要:
本文研究了万寿菊根的提取物对西瓜枯萎病菌和西瓜幼苗的影响。结果表明 ,万寿菊根的提取物对供试的西瓜枯萎病菌菌丝生长有明显的抑制作用 ;同时 ,经对西瓜幼苗根和叶的酶活性测定和过氧化物同工酶电泳分析的结果表明 ,该提取物能诱导西瓜保护酶如超氧化物歧化酶 (SOD)和过氧化物酶 (POD)活性提高 ,减轻西瓜枯萎病菌粗毒素对西瓜幼苗的毒害作用

摘  要:
The effect of extract from root of Tagetes patula on watermelon Fusarium oxysporum and watermelon seedling was primarily studied. The superoxide dismutase (SOD) and peroxidase (POD) enzymic activity assay and electrophoresis ana- lyse of peroxidase isozyme showed that extract had remarkable inhibition effect on the mycelium growth of F.oxysporum, and they can induce the activity of protective enzymes, reduced the harm of crude toxin of F.oxysporum to watermelon seedling.
