| 摘 要： | 本文报导了用松材线虫(Bursaphelenchus xylophilus)感染15种松树后,不同松树品种的枯死率不同,也就是抗病性不同.在供试的15个松树品种中,黑松为国际上公认的感病树种,感病程度高于黑松的有白皮松(Pinus bungeana)、赤松(P.densiflora)、东北红松(P.koraiensis)、华山松(P.armandii)、华南五针松(P.kwangtung ensgs)、湿地松(P.elliottii)和云南松(P.yunnanensis)等7个品种.感病程度低于黑松的有黄山松(P.taiwanensis)、樟子松(P.sylvestris var.mongolica)、乔松(P.griffithi)和粤松(P.fenzeliana)。而高度抗病的有火炬松(P.taeda)、马尾松(P.massoniana)和短叶松(P.banksiana).接种时间的不同影响松树的抗性,春季接种后树木渡过一个炎热的夏季,松树的枯死率比秋季接种的要高.

| Abstract: | Two-to four-yr old seedlings of 15 pine species growing in field of Hunan and Shandon were inoculated through a branch cut with 7000-8000 Eursaphelenchus xylophilus,originally collected from a dead Pinus thunbergii in Nanjing City.The susceptibility of P.bungeana,P.densiflora,P.elliottii,P.koraiensis,P.armandii,P.kwangtungensis,and P.yunnaneusis is higher than that of P.thunbergii.The susceptibility of P.taiwanensis,P.sylvestris var.mongolica,P.griffithi,and P.fenzeliana is lower than that of P.thunbergii,P.taeda,P,massoniana and P.banksiana are highly resistant.The wilt proportion of pine seedlings inoculated in Spring were higher than that in Fall. |
