摘  要：
以小麦赤霉病菌(Fusarium graminearum)、玉米小斑病菌(Bipolaris maydis)和玉米弯孢叶斑病菌(Curvu laria)为供试菌,采用菌丝生长速率法和悬滴法,对白术和白头翁2种植物提取物的抗菌活性进行了研究。结果表明:在供试浓度为10 mg.mL-1时,白术乙酸乙酯提取物对小麦赤霉病菌的抑菌活性较高,对菌丝生长的抑制率为80.68%,对小麦赤霉病菌孢子萌发的抑制率为89.25%,EC50为4.27 mg.mL-1。白头翁石油醚提取物对玉米小斑病菌的抑菌活性较高,对菌丝生长的抑制率为75.33%,对玉米小斑病菌孢子萌发的抑制率为94.21%,EC50为2.84 mg.mL-1。

摘  要：
Taking Fusarium graminearum,Bipolaris maydis and Curvu laria as experimental materials,using growth rate and hanging drop methods,the antifungal activity of the extracts from two species of plants(Atractylodes macracephal Koidz and Pulsatilla chinensis Bunge Regel) against Fusarium graminearum,Bipolaris maydis and Curvu laria were studied under the condition of laboratory.The results showed that the extracts of all the two plants showed antifungal activity against the tested pathogenic fungi at 10 mg·mL-1.Especially the antifungual activity of the extract of Pulsatilla chinensis Bunge Regel was stronger against Fusarium graminearum,the rates of inhibition to the mycelium growth was 80.68%,89.25% inhibition of spore germination and the EC50 of the former was 4.27 mg·mL-1.At the same concentration,the extract of the plants in Atractylodes macracephal Koidz showed stronger inhibition against Bipolaris maydis,the rates of inhibition to the mycelium growth was 75.33%,94.21% inhibition of spore germination and the EC50 of the former was 2.84 mg·mL-1.
