摘要:

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。

Abstract: As a national Ⅱ protected plant in China, Tilia amurensis Rupr. is an important tree species for nectar source, medicine and landscape. The resources of ectomycorrhizae colonizing T. amurensis were investigated in three typical distribution areas of T. amurensis in Heilongjiang Province. A total of 18 ectomycorrhizal types were grouped by observing morphological and anatomical characteristics of T. amurensisassociated ectomycorrhizae, of which 13 were formed by basidiomycetes, 1 by ascomycytes, and 4 unknown. Our study provides a morphological basis for mycorrhizal seedlings of T. amurensis.
