摘要
运用形态学方法,结合同工酶电泳和线粒体DNA标记技术,对采自海南省10市县的28个番石榴根结线虫种群进行鉴定,明确了25个种群为湛江根结线虫M eloidogyne zhanjiangensis、2个种群为番禺根结线虫M.panyuensis、1个种群为南方根结线虫M.incognita,湛江根结线虫是危害海南省番石榴的优势种群.文中对根结线虫的鉴定技术与方法作了讨论.
Twenty eight root-knot nematode populations on Psidium guajava were collected from Hainan Province. Based on morphology, isozyme and mtDNA, 25 populations were identified as Meloidogyne zhanjiangertsis ,2 populations as M. panyuertsis and 1 population as M. incognita. It was showed that M. zhanjiangensis was the predominant species. The technology and methods of identification on root-knot nematode were discussed in the paper.
