Abstract

Abstract 9. Abstract Roots of ectomycorrhizal and ericoid mycorrhizal plants are believed to be colonized by fungi belonging to different taxonomic groups. However, both frequent isolations of ericoid mycorrhizal fungi from ectomycorrhizal root tips and a few recent studies (Vrålstad et al. 2000, 2002b, Piercey et al. 2002, Hambleton & Sigler 2005) indicate that there is a group of mycobionts colonizing both types of roots. Ectomycorrhizal morphotype Piceirhiza bicolorata was shown to be induced by Meliniomyces sp. belonging to the Rhizoscyphus ericae aggregate (Vrålstad et al. 2000). The ability to colonize roots of potentially ectomycorrhizal and ericoid plants simultaneously was proven in in vitro experiments in the case of Rhizoscyphus ericae (Pirecey et al. 2002) and Cadophora finlandica (Villarreal­Ruiz et al. 2004). DSE fungi ("dark septate endophytes", formerly termed pseudomycorrhizal) represent another group of mycobionts colonizing both ericoid and potentially ectomycorrhizal plant roots. In the present work, we inoculated roots of ericoid (Vaccinium myrtillus) and potentially ectomycorrhizal plants (Picea abies, Pinus sylvestris and Betula nana) with typically ectomycorrhizal and ericoid mycorrhizal fungi and...
