摘  要:
文章记叙了 1 91 1年以来松枝枯病 Cenangium ferruginosum Fr.ex Fr.的研究史上关于病菌的寄生性和致病性的争论 ,一种意见认为该菌是有寄生性的致病菌 ;一种意见认为完全是腐生菌。随着人工培养和在衰弱寄主上接种的成功 ,多数人承认它是一种弱寄生菌 ,其致病能力与环境胁迫所造成的树势衰弱相伴随。影响发病最主要的环境因子是气候干旱。近年研究证明 ,Cenangiumferruginosum是松树健康针叶中的一种占优势的内寄生菌 ,虽然它从未在针叶上产生症状 ,但有人推测 ,在针叶和小枝之间有相互系统蔓延的关系。文章还较详细地回顾了国内有关研究情况 ,并介绍了主要文献索引

摘  要:
The paper reviewed th e controversy on parasitism and pathogen esis of Cenangium ferruginosum Fr.ex F .causing pine die-back since 1911.One re cognized that the fungus was really para sitic,but the others concluded that it w as entirely saprophytic.Along with the s uccess of its cultural technology and in oculation on weak hosts,it was gene ral ly accepted that the fungus was a weak p arasitism and its pathogenicity was conc omitant with a host vigor reduction caus ed by environment stress.The greatest fa ctor of environment was drought.In recen tly years,the reports showed that C.fer ruginosum was an endophytic fungus domi nating in healthy needles of pine.Althou g h the symptom has not been discovered on needles,some suggested that the fungus may systemically colonize each other bet ween needles and twigs.The paper detaile d internal literature and recommended som e major references.
