【摘要】 对采自中国南方地区34种作物的根结线虫83个种群进行了单卵块纯化和培养,在形态学研究的基础上,结合利用全自动快速水平电泳系统测定了雌虫的酯酶和苹果酸脱氢酶,鉴定出南方根结线虫(Meloido-gyne incognita)、爪哇根结线虫(M.javanica)、花生根结线虫(M.arenaria)和番禺根结线虫(M.panyuensis)。其中南方根结线虫是最主要的根结线虫。鉴别寄主试验表明,南方根结线虫的优势小种是1号小种。更多还原

【Abstract】 Single egg mass purification and multiplication of root-knot nematode populations collected from Southern China were conducted on tomato seedling in greenhouse. Meloidogyne incognita ,M. javanica,M. arenaria and M. panyuensis were identified based on morphology and isozyme. The result indicated that M. incognita was main root-knot nematode. Differentiation host reaction showed that M. incognita race 1 was prevailing in population. This conclusion is valuable for management of rootknot nematodes in China.更多还原
