采用形态学和分子生物学方法（聚合酶链反应-限制性片段长度多态性）研究了青海云杉（Picea engelmannii Parry ex Engelm.）在不列颠哥伦比亚省中部的两个最近砍伐的地点、两个砍伐和广播烧毁的地点和两个成熟的森林（> 100年）中的云杉（Picea glauca（Moench）Voss）幼苗。基于24个特征ECM，燃烧并不影响整体多样性（香农，辛普森，香农均匀度，和Margalef指数）。然而，一些ECM形态型的发生和相对丰度变化显着。Hebeloma和红菇科1型更丰富，Cenococcum是不太丰富的种植幼苗从削减烧毁网站相比，那些从皆伐网站。E-菌株，MRA，和Amphinema更丰富的种植幼苗从切烧和皆伐网站相比，自然再生幼苗从成熟的网站。再生苗ECM多样性研究
Morphological and molecular (polymerase chain reaction restriction fragment length polymorphism) methods were used to assess ectomycorrhiza (ECM) diversity in naturally regenerating and planted Picea engelmannii Parry ex Engelm. × Picea glauca (Moench) Voss seedlings in two recently clear-cut sites, two clear-cut and broadcast burned sites, and two mature forests (>100 years) in central British Columbia. Based on 24 characterized ECM, burning did not affect overall diversity (Shannon, Simpson, Shannon evenness, and Margalef indices). However, the occurrence and relative abundance of some ECM morphotypes varied significantly. Hebeloma and a Russulaceae type 1 were more abundant and Cenococcum was less abundant in planted seedlings from cut-burned sites compared with those from clear-cut sites. E-strain, MRA, and Amphinema were more abundant in planted seedlings from both cut-burned and clear-cut sites compared with naturally regenerating seedlings from mature sites. ECM diversity of regenerating seedling...
