报道了太白山自然保护区外生菌根及菌根真菌的调查研究结果。共获得外生菌根真菌 2 8种 ,隶属6科 18属 ;查明主要菌根树种是巴山冷杉 (Abiesfargesii Franch)和太白红杉 (L arix chinensis Beissn)。主要菌根真菌是红菇 (Russuluceae)和牛肝菌 (Boletaceae)。并对其生态分布进行了分析 ,以亚高山 (Subalpine belt)南坡 2 85 0～3 30 0 m、北坡 3 0 0 0～ 3 2 0 0 m区带最适合于菌根 (Mycorrhiza)及菌根真菌子实体 (Mycorrhiza fungi fruit bodies)的形成。
The investigation results of ectomycorrhizal and mycorrhizal fungi in Taibai Mountain Nature Reserve were reported. Eighteen species of ectomycorrhizal fungi were obtained, belonging to 6 families and 18 genera. The main mycorrhizal species were identified as Abiesfargesii Franch and L arix chinensis Beissn. The main mycorrhizal fungi are Russuluceae and Boletaceae. The ecological distribution of the subalpine belt was analyzed and the most suitable for Mycorrhiza and Mycorrhiza belts were from 2 85 0 to 3 30 0 m on the southern slope of Subalpine belt and 3 0 0 to 3 2 0 0 m on the northern slope and Formation of Mycorrhiza fungi fruit bodies.
