| 摘 要： | 从陕西秦巴山区及关中西洋参种植区的种子、锈腐病根及参地土壤中,分离到8种柱孢属(Cylindrocarpon)真菌和一个变种.C.destructans(Zins.)Scholtcn,C.obtusisporum(Cook＆Harkcss)Wollcnw,C.vaginae C.Booth,Y.M.Clayton＆MuUsherwood及C.victoriae(P.Hcnncn cx Wr.)Wollcnw.为引致当地西洋参锈腐病的致病菌.其中以C.destructans致病性最强,并在数量和存在的普遍性方面占优势,C.obtusisporum次之.上述4种柱孢中的后3种,及C.didymum(Harting)wallcnw.,C.heteronema(Bcrk＆Br.)Wollcnw.,C.decumbens Wollcnw.和C.destructans(Zins)Scholtcnvar.crasum Wollcnw.为国内新记录.文中对主要锈腐病原的科学名称进行了讨论。

| Abstract: | 8 species and a variety of the genus Cylindrocarpon were obtained from seeds , diseased roots of Panax quinqucfolium and soil samples of ginseng field in Qinl-ing , Bashan Mountain area and the Central Plain ofShaanxi Province. Among them C. destructans (Zins.) scholtcn, C. obtusisporum (Cook & Harkcss) Wollcnw, C. vaginae C. Booth , Y. M. Clayton & Mu Ushcrwood and C. victoriac (P. Hcnncn ex wr.) Wollcnw. arc the causal agents of the root rust rot disease of American ginseng. C. destructans is one of the most virulent pathogen and wide spread. C. obtusisporum lakes the second position. The last three of the four species mentioned above and C. n(Harling) Wallcnw. C. hetcronema (Berk & Br.) Wollcnw. C. decumbcns Wolltcnw. and C. destructans (Zins. ) SchoUcn Var. crasum Wollcnw. arc new record species for China. The scientific name of the main pathogen of the disease was discussed. |
