摘要: 从江苏省南京市江宁区、南京市紫金山、镇江市、淮安市、连云港市和扬州市等5个市6个地区采集80份马尾松(Pinus massoniana)、黑松(P. thunbergii)、湿地松(P. elliottii)和赤松(P. densiflora)的根和根际土壤样品,并分离鉴定其中的寄生线虫,初步分析结果如下:从采自南京紫金山上健康的马尾松根际中分离得到双宫螺旋线虫(Helicotylenchus dihystera)和松拟盘旋线虫( Paratylenchus pini);从南京江宁区衰弱马尾松根际中分离得到斯氏细小线虫(Gracilacus steineri)、尖头细小线虫(G. epacris)和斯特林细小线虫(G. straeleni),从健康马尾松根际中分离得到布科文针线虫( P. bukowinensis);从扬州市健康的马尾松根际中分离得到苹果矮化线虫(Tylenchorhynchus malinus);从镇江市健康黑松根际中分离得到微小针线虫(P. minutus)。其中,马尾松是苹果矮化线虫、布科文针线虫、斯特林细小线虫、尖头细小线虫和斯氏细小线虫的新寄主,黑松是微小针线虫的新寄主。同时,布科文针线虫、斯特林细小线虫、尖头细小线虫和斯氏细小线虫为江苏省的新纪录种。

Abstract: Isolation and species identification of the rhizosphere parasitic nematodes were carried out from 80 roots and soil samples, which were collected from Pinus massoniana, P. thunbergii, P. elliottii, P. densiflora from Nanjing, Zhenjiang, Huaian, Lianyungang and Yangzhou cities in Jiangsu province. The results were as follows:Helicotylenchus dihystera and Paratylenchus pini were isolated from the rhizosphere of healthy P. massoniana grown in Mount Zijin of Nanjing City; Gracilacus steineri, G. epacris and G. straeleni were found in the rhizosphere of weak P. massoniana in Jiangning district of Nanjing City; Tylenchorhynchus malinus were observed in the rhizosphere of healthy P. massoniana in Yangzhou City; P. minutus were from healthy P. thunbergii in Zhenjiang City. P. massoniana was a new host of T. malinus, P. bukowinensis, G. straeleni, G. epacris and G. steineri, while P. thunbergii was a new host of P. minutus. Moreover, P. bukowinensis, G. steineri, G. epacris and G. straeleni were the new record species in Jiangsu province.
