摘要
在形态学鉴定的基础上,运用同工酶电泳技术,对采自陕南3市18县区的37个为害蔬菜的根结线虫种群进行鉴定。结果表明:在所鉴定的种群中,32个种群为南方根结线虫(Meloidogyne incognita),2个种群为花生根结线虫(M.arenaria),1个种群为北方根结线虫(M.hapla),1个种群为南方根结线虫和花生根结线虫的混合群体,1个种群为南方根结线虫和北方根结线虫的混合群体;其中南方根结线虫是陕南为害蔬菜的主要根结线虫。
Thirty-seven root-knot nematode populations on vegetables were collected from South Shaanxi.Based on morphology and isozyme,32 populations were identified as Meloidogyne incognita,2 populations as M.arenaria,1 populations as M.hapla,1 population as a mixture of M.incognita and M.arenaria and 1 population as a mixture of M.incognita and M.hapla.The results indicated that M.incognita was the predominant species in South Shaanxi.
