| 摘 要： | 采用生长速率法和孢子萌发法测定了20种植物丙酮提取物对番茄早疫病菌(Alternaria solani)、玉米大斑病菌(Exserohilumturcicum)的抑制效应。研究结果表明,在供试质量浓度为0.01 g/mL时,老瓜头、蛇果黄堇、小蓝雪花、苦豆子、苍耳、针叶短枝芸香等6种植物提取物对番茄早疫病菌菌丝生长抑制率大于60%,对番茄早疫病菌、玉米大斑病菌孢子萌发的抑制作用较强,抑制率均在80%以上,其中小蓝雪花提取物对番茄早疫病菌菌丝生长的抑制率为100%,对2种供试菌孢子萌发的抑制率分别为92.1%和95.3%。

| Abstract: | With growth rate and spore germination method,biological activity of twenty acetone extracts were assayed against Alternaria solani and Exserohilum turcicum.The results showed that in the tested concentration 0.01 g/mL,six plant extracts had more than 60% inhibition of mycelium growth in A.solani,and more than 80% inhibition of spore germination in A.solani and E.turcicum,they were Cynanchum komarovii Al.iljinski,Corydalis ophiocarpa,Plumbagella micrantha spach,Sophora alopecuroides Linn.,Xanthium sibiricum... |
