摘要:

为绿色防治茎基腐病,开发植物源杀菌剂资源,采用生长速率法测定丁香等15种中草药提取物对百香果茎基腐病病原菌尖孢镰刀菌的抑制作用。根据室内毒力测定结果分析,15种中草药提取物对百香果茎基腐病均有不同程度的抑制效果,抑制效果由强至弱依次为丁香>川芎>高良姜>厚朴>黄连>木香>当归>莱菔子>黄芩>细辛>艾叶>板蓝根>百部>黄精>地肤子。丁香、川芎、高良姜提取物的抑菌作用最佳且稳定,当浓度为20、80、80 mg/mL时,抑制率达到100%。经毒力回归方程分析,丁香、川芎、高良姜提取物对供试菌株的EC50分别为1.46、1.66、1.81 mg/mL。

Abstract:

To prevent and control the stem base rot and develop botanical fungicide resources, the growth rate method was used to determine the inhibitory effect of 15 kinds of Chinese herbal medicine extracts, such as Eugenia aromatica, on passion fruit stem base rot pathogen Fusarium oxysporum. According to the indoor toxicity test results, the 15 kinds of Chinese herbal medicine extracts had inhibitory effect degree from high to low as: Eugenia aromatica> Rhizoma ligustici> Alpinia officinarum> Magnolia officinalis> Coptis chinensis> Aucklandia lappa> Angelica sinensis> Raphanus sativus> Scutellaria baicalensis> Asarum sieboldii> Artemisia argyi> Isatis indigotica> Stemona japonica> Polygonatum sibiricun> Kochia scoparia, among which Eugenia aromatica, Rhizoma ligustici and Alpinia officinarum extracts had the best and stable antibacterial effects. When the inhibitory concentration of the above three extracts was 20, 80 and 80 mg/mL respectively, the inhibition rate could reach 100%. The virulence regression equation analysis showed that the EC50 of Eugenia aromatica, Rhizoma ligustici and Alpinia officinarum extracts to the tested strains was 1.46, 1.66 and 1.81 mg/mL, respectively.
