| 中文摘要: |
| 以牡丹皮等16种中草药的丙酮提取物为材料,测定了其对5种植物病原菌的生长抑制活性。结果表明:在供试质量浓度为0.05 g/mL时,牡丹皮提取物对所有供试病原菌菌丝生长抑制效果最好,除对杨树溃疡病菌菌丝生长抑制率为85.3%外,对其他植物病原菌的抑制率均为100%。高良姜提取物抑菌活性次之,对4种供试植物病原菌菌丝生长抑制率均在80%以上,对番茄灰霉病菌的抑制率最低,也达到68%。黄芩提取物对供试的3种植物病原菌的抑制率超过60%。连翘、知母、蔓荆、乳香和地榆等5种中药提取物分别对供试的5种植物病原菌中的2种有较好的抑菌活性。在供试质量浓度为0.1 g/mL时,牡丹皮、高良姜等2种中药提取物对杨树溃疡病菌孢子萌发抑制作用相当明显,抑制率均在80%以上;白花蛇舌草、乳香、川楝等3种中药提取物对杨树溃疡病菌孢子萌发抑制作用次之,抑制率均在60%以上。 |

| To screen the active ingredients against plant pathogen,the inhibitory activity of sixteen kinds of Chinese herbs against 5 plant pathogens were examined.The results showed that the extracts of cortex moutan had a good inhibiting rate to all of the five kinds of plant pathogens,and the extracts of Alpinia officinarum also showed good anti-fungal properties with more than 80% inhibiting rate to at least four kinds of plant pathogens at the concentration of 0.05 g/mL.The inhibiting rate of the extracts of cortex moutan and Alpinia officinarum to the growth of the spore of Dothiorella gregaria was more than 80% at the concentration of 0.1 g/mL,while that of other three Chinese herbs were more than 60%. |
