紫椴是国家Ⅱ级保护植物,是重要的蜜源、药用以及城市绿化树种。本研究首次调查了黑龙江省3个紫椴典型分布区域的外生菌根资源,通过观察紫椴外生菌根的形态与解剖结构,将紫椴外生菌根初步划分为18种类型,其中子囊菌1种,担子菌13种,4种未知类型。可为紫椴菌根化育苗提供形态学基础。 Tilia is a national grade Ⅱ protected plants, is an important source of honey, medicinal and urban afforestation species. In this study, the ectomycorrhizal resources of three typical Tilia amurensis populations in Heilongjiang Province were investigated for the first time. By observing the morphology and anatomy of the ectomycorrhizae, the ectomycorrhizae of Tilia amurensis were initially divided into 18 types 1 species of ascomycetes, 13 species of Basidiomycetes, 4 unknown types. For Tilia amurensis seedling provide morphological basis.
