摘要: 对中国野生葡萄资源的l7个种或变种,共73个株系根围寄生线虫的种类和密度进行了系统
的调查与鉴定。共采集300份土样,从中鉴定出线虫计9属l9种:6种螺旋线虫,4种剑线虫,2种短体线虫,2种矮化线虫;长针线虫、针线虫、盘旋线虫、轮线虫和枪线虫各1种。线虫群体一般由2—5个属组成,其中针线虫、螺旋线虫和矮化线虫是分布较广泛的寄生线虫。同时比较了中国野生葡萄的不同种,不同株系间寄生线虫种类和密度的差异,为进一步筛选抗线虫砧木提供了依据。

Abstract:

Species and densities of parasitic nematode8 were systematically investigated from the daizosphere soil of 73 clone 8 which belong to 17 species of wild grapes native to China. 19 species of plant nematodes belonging to 9 genera respectively were identified from 300 soil samples,which contained six species of Helicotylenchus,four species of Xiphinema, two species of Paratylenchus, two species of Tylenchorhynchus, and one species of Longidorus, ParatylenchusRotylenchusCriconemoides and Hoplolaimus each. Nematode population usually consisted of 2—5 genera.Three genera i.e Helicotylenchus, Paratylenchus and Tylenchorhynchus spread widely in many wild clones.Differences of nematode genera and densities among diferent wild clones were given.The results would be basis for stock selection resistant to parasitic nematodes.
