摘要
松材线虫萎蔫病是由松材线虫[Bursaphelenchus xylophilus(Steiner&Buhoror)Nickle]引起的松属树种上一种毁灭性的病害,目前对该病的致病机理尚不十分清楚。本研究采用松材线虫的6个虫株和拟松材线虫的1个虫株对1年生黑松苗进行致病性测定。结果表明,1、6号虫株致病性较强;2、5号虫株致病性较弱;3号和4号致病性居中。6个虫株的松材线虫最终都能导致黑松死亡,拟松材线虫不具有致病性。
Pine wilt disease caused by pine wood nematode [Bursaphelenchus xylophilus （Steiner ＆ Buhrer） Nickle] is a ruinous disease for pine, but the pathogenesis has not been quite clear so far. To this end 6 types of B. xylophilus and one type of B. mucronatus were used to test for pathogenicity to Pinus thunbergil. The result showed that the pathogenicity of Nematode 1 and 6 was strong but that of Nematode 2 and 5 was weak; and that of Nematode 3 and 4 was between. All the isolates of B. xylophilus can kill Pinus thunbergii, but B. mucronatus has not pathogenicity.
