核盘菌近缘种的分类研究

Taxonomic Study of Sclerotinia Sclerotiorum and Related Species

从采集和分离到80多个核盘菌株,对其中28个代表菌株(种和菌系)进行形态学和培养性■以及菌株间菌丝交接反应研究。两种分类鉴定方法对供试菌株的分类结果完全一致。28株供试菌株共分为5个种,属于核盘菌有4个种,即核盘菌Sclortinia sclerotiorum(Lib.)de Bary,三叶草核盘菌S.trifoliorum Erikss,细辛核盘菌S.asari Wu ct.C.R.Wang和人参菌核病菌Sclerotinia sp.。有2个菌株属于Botrycis cincrea.

For research on classification of Sclerotinia sclerotiorum and related species, more than 60 cultures of Sclerotinia species were collected and isolated from different cultivars from south and north China from 1979 to 1984. Among them, 28 isolates were selected for study in morphologic and cultural characters as well as in mycelial interaction. Two methods of classification reached the same result. 28 isolates were divided into 5 species, of which 4 species belonged to Sclerotinia Fuckel. They were S. sclerotiorum (Lib. ) de Bary, S. trifoliorum Eriks., S. asariWu et C. R. Wang and Sclerotinia sp. an isolate from Panax ginseng. The other species was Botrytis cinerea Pers.
