| 摘 要： | 选择三种野生有毒植物白屈菜、胡桃楸和细叶杜香及常见植物蒲公英，研究了它们对三种黄单胞菌属植物病原细菌的抑菌作用．提取四种植物有效成分的提取液，采用96孔板法测定四种植物的最低抑菌浓度（MIC），并用带药平板法检验．试验结果表明，白屈菜、胡桃楸和蒲公英对三种植物病原细菌都有不同程度的抑菌活性．白屈菜（茎叶）和蒲公英抑菌活性较强，对三种植物病原细菌的最低抑菌浓度分别为0．1g／ml、0．1g/ml、0．05g/ml，白屈菜（根）和胡桃楸抑菌活性稍差，细叶杜香提取液未检测到抑菌能力．

| Abstract: | To research the antimicrobial actions of three kinds of wild poisonous plants Chelidoniummaius L.,Juglans mandshurica Maxim,Ledum palustre L.var and common plant Taraxacum for three plant-pathogenic bacteria of Xanthomonas.Extracted crude extracts of bioactive ingredients from four plants,and tested the minimal inhibitory concentration(MIC) by 96-well plates,verified by the plate method with drug.The results of experiments showed that Chelidoniummaius L.,Juglans mandshurica Maxim and Taraxacum have varying degrees of antimicrobial actions to three plant-pathogenic bacteria.Chelidoniummaius L.(stem and leaf) and Taraxacum have more powerful antimicrobial actions,the minimal inhibitory concentration to three plant-pathogenic bacteria were 0.1g/ml、0.1g/ml、0.05g/ml,respectively.The antimicrobial actions of Chelidoniummaius L.(root) and Juglans mandshurica Maxim was less,and the antimicrobial actions of Ledum palustre L.var couldn’t be detected. |
