【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。
[Abstract]:During the investigation of plant nematode species in the main farming areas of Tibet Autonomous region of China, samples of root tissue and rhizosphere soil of many crops were collected from Linzhi region and Dazi County of Lhasa City. A number of plant nematode species were isolated from these samples by the improved Beiman funnel method. According to the morphological characteristics, (Pratylenchus loosi), and P.scribneri were identified. In comparison with the population described in the literature, the population of Xizang was shorter, and the other morphological characteristics were basically the same. The morphological characteristics of the population of Xizang population and Scribner nematodes in Tibet were basically consistent with those described in the literature. Among them, there are two species in Linzhi area and Lhasa county, and the other two species are distributed in Linzhi area.
