| 摘 要： | 目的]探讨橡胶树黑团孢叶斑病菌培养滤液对薇甘菊(Mikania micrantha H.B.K.)的除草活性。方法]采用室内生物活性测定方法,研究了7种植物病害真菌培养滤液对恶性入侵杂草薇甘菊种子萌发和幼苗生长的抑制作用,并评价了橡胶树黑团孢叶斑病真菌培养滤液对辣椒和番茄的安全性。结果]橡胶树黑团孢叶斑病病原真菌培养滤液对薇甘菊种子萌发以及根、茎、幼苗生长均有较强的抑制作用,抑制率分别达72.7%、93.0%、32.4%和54.6%(鲜重)。橡胶树黑团孢叶斑病病原真菌培养滤液对番茄种子萌发和根茎生长均表现安全,而对辣椒种子萌发有抑制作用。结论]橡胶树黑团孢叶斑病病原真菌毒素培养滤液及其代谢物值得作为生物除草剂进一步开发。

| Abstract: | Objective] The paper was to explore the herbicidal effect of Periconia heveae culture filtrate on Mikania micrantha.Method] Through indoor bioassay method,the inhibitory effects of culture filtrates of seven kinds of plant disease fungi on seed germination and seedling growth of M.micrantha were studied,and the security of P.heveae culture filtrate on pepper(Capsicum annuum) and tomato(Solanum lycopersicum) was also evaluated.Result] The culture filtrates of P.heveae had strong inhibitory effects on seed germination and the growth of root,shoot and seedling of M.micrantha,and the inhibition rates were 72.7%,93%,32.4%,and 54.6%(fresh weight),respectively.Security tests showed that culture filtrates of P.heveae were safe to seed germination and root and shoot growth of tomato,but they inhibited seed germination of pepper.Conclusion] As potential biological herbicide,the culture filtrate and metabolites of P.heveae is worthy of further development. |
