摘要
在对我国西藏自治区主要耕作区的植物线虫种类进行调查期间,从林芝地区、拉萨市达孜县采集多种作物的根系组织和根际土壤样品,并采用改良贝曼漏斗法从这些样品中分离出了多种植物线虫,根据形态学特征,从中鉴定出卢斯短体线虫(Pratylenchus loosi)、落选短体线虫(P.neglectus)和斯克里布纳短体线虫(P.scribneri)。其中,卢斯短体线虫西藏种群与文献描述的种群相比尾较短,其他形态特征基本一致;落选短体线虫西藏种群和斯克里布纳短体线虫西藏种群分别与文献描述种群的形态特征基本一致。其中,落选短体线虫在林芝地区和拉萨市达孜县均有分布,另外2个种均分布于林芝地区。
Soil and root samples were collected from the rhizosphere of crops during the survey of plant nematodes in the main cultivation area in Tibet.Plant nematodes were isolated from these samples by using the modified Baermann funnel method.Based on morphological characteristics,three species,Pratylenchus loosi,P.neglectus and P.scribneri from genus Pratylenchus were identified.The P.loosi populations from Tibet has a shorter tail than those described in literatures.The main morphological characteristics and measurements of the P.neglectus and P.scribneri populations in Tibet were similar to those described in literatures.The P.neglectus was distributed in Nyingchi and Lhasa area,and the other two species were distributed in Nyingchi.
