摘要
对采自湖北省烟草(Nicotiana tabacum Linn.)种植地的8份根围土和根组织线虫样本进行分离,通过系统的形态学观测,共鉴定出6属8种植物线虫:异头丝尾垫刃线虫(Filenchus heterocephalus)、咖啡短体线虫(Pratylenchus coffeae)、刻痕短体线虫(Pratylenchus crenatus)、扁尾螺旋线虫(Helicotylenchusplatyurus)、拟强壮纽带线虫(Hoplolaimus pararobustus)、花生根结线虫(Meloidogyne arenaria)、南方根结线虫(Meloidogyne incognita)和燕麦真滑刃线虫(Aphelenchus avenae),其中异头丝尾垫刃线虫、刻痕短体线虫和拟强壮纽带线虫为中国烟草上首次报道的植物线虫。对鉴定出的部分线虫种类进行了详细的形态学描述,并讨论了8种植物线虫对烟草的经济重要性。
Eight rhizosphere soil and root samples of tobacco（Nicotiana tabacum Linn.） were collected from Hubei province during 2010 to 2011,from which nematodes were isolated and morphologically identified.From six plant nematode genera,eight plant nematode species were identified-Filenchus heterocephalus,Pratylenchus coffeae,P.crenatus,Helicotylenchus platyurus,Hoplolaimus pararobustus,Meloidogyne arenaria,M.incognita,and Aphelenchus avenae,among which F.heterocephalus,P.crenatus and H.pararobustus were firstly reported on tobacco in China.The former five species were described in detail,and all eight species were discussed on the economic importance to tobacco.
