| 摘 要： | 目的]研究9种药用植物粗提物对3种植物病原真菌的抑菌活性。方法]采用生长速率法测定了采自西双版纳热带植物园的9种药用植物丙酮粗提物对茄链格孢菌(Alternaria solani)、腐皮镰刀菌(Fusarium solani)和香蕉炭疽菌(Colletotrichum musae)的抑菌活性。结果]在不同的植物样品浓度(0.100、0.010和0.005 g/ml)下,9种药用植物丙酮粗提物对3种供试植物病原真菌的菌丝生长均表现出一定的抑制活性,抑菌率在3.5%～87.0%。结论]凤仙花(Impatiens balsamina)对3种植物病真菌菌的抑菌率为12.8%～87.0%,穿心莲(Andrographis paniculata)则为40.0%～69.8%,二者具有进一步研究和开发的价值。 |

| Abstract: | Objective] The aim was to study the antifungal activities of extracts from 9 medicinal plants on 3 phytopathogenic fungi.Method] The antifungal activities of extracts from 9 medicinal plants in Xishuangbanna tropical botanical garden on Alternaria solani,Fusarium solani,and Colletotrichum musae were determined by growth rate methods.Result] The results indicated that acetone extracts with different concentration(0.100、0.010 and 0.005 g/ml) from the 9 medicinal plants showed inhibition activities on the mycelia growth of 3 sampled phytopathogenic fungi,and the inhibition rate were from 3.5% to 87.0%.Conclusion] The inhibition rates of Impatiens balsamina on 3 fungi were from 12.8% to 87.0%,and from 40.0% to 69.8% of Andrographis paniculata.The I.balsamina and A.paniculata had values for further research and development. |
