【摘要】 通过对滇中地区昆明西山、昆明野鸭湖、嵩明大哨和楚雄紫溪山分布的蛹虫草居群,进行调查和采样,调查分析了蛹虫草的生境,比较研究了蛹虫草不同居群有性型及无性型形态差异,对蛹虫草无性型的产孢结构进行光学显微镜和扫描电镜观察研究。研究发现,蛹虫草子囊壳着生方式及其大小、子囊大小、无性型,随生境不同而发生差异。在云南松常绿阔叶混交林下的子囊壳及子囊较大,分离得到的无性型以拟青霉型(Paecilomyces-type)产孢结构占优势;在华山松林和田埂草丛生境中的子囊壳及其子囊较小,分离得到的无性型以轮枝孢型(Verticillium-type)产孢结构占优势。
【Abstract】 In the present studying of Cordyceps militaris(Fr.) Link.,a lot of specimens were collected from Kunming city and Chuxiong city,Yunnan Province.According to investigate their habitats,the comparing analysis was dealt with the morphological characters of their teleomorph and anamorph,and the conidial fructification was observed.It was showed that the features of perithecium,ascus and anamorph were different amongdifferent habitats.In the habitat of evergreen broad-leaved forest coexisting Pinus y...
