摘  要:
采用9种中药材的乙醇提取液(用药浓度为1000μg/mL),对油菜菌核病菌、小麦赤霉病菌、小麦纹枯病菌、苹果轮纹病菌、番茄灰霉病菌进行了抑菌试验,结果发现,9种中药材乙醇提取物对5种植物病原菌均表现出不同程度的抑制作用。其中穿心莲抑菌作用范围最广,对5种植物病原菌抑菌率均超过50%。尤其是对苹果轮纹病菌抑菌作用最强,抑菌率达到了96.96%,效果最好。远志对油菜菌核病菌抑菌率达82.37%,对苹果轮纹病菌达66.55%,抑菌效果明显。甘草也有较好的抑菌效果。对穿心莲、远志、甘草作植物源杀菌剂值得进一步研究。

摘  要:
Antifungal activity of 9 alcohol extract of Andrographis paniculate,Polyala tenuifolia Willd,Mentha haplocalyx Briq,Sterculia scaphigera Wall,Dryopteris Crassirhixoma Nakai(concentration is 1000g/mL)were assayed against Sclerotinia sclerotiorum,Fusarium graminearum,Rhizoctonia cerealis,Botryosphaeria berengriana,Botrytis cinerea by measuring growth rates of pathogens.The alcohol extracts of 9 Chinese mendicines had different inhibition to the 5 different fungi species.Alcohol extract of Andrographis paniculate had the widest spectrum of inhibition,which provided over 50% inhibition of all the 5 fungi species,and 96.96% inhibition of Botryosphaeria berengriana.Polyala tenuifolia extract had 82.37% inhibition of Sclerotinia sclerotiorum,and 66.55% inhibition of Botryosphaeria berengriana.Alcohol extract of Glycyrrhiza uralensis could effectively inhibit the growth of pathogenic fungi.Tthe antifungal activity of the Andrographis paniculate,Polyala tenuifolia and Glycyrrhiza uralensis needs further study.
