Abstract:: The colonization of several species of plants by vesicularar-buscular mycorrhizae (VAM) was studied to determine how host, soil, or symbiont factors interacted to enhance growth of the host plant. Seedlings of two species of the Cuppressaceae and two of the Taxodiaceae formed VAM; colonization significantly improved growth. This response to...

Creator:: Kluber, Laurel A.
Abstract:: Dense hyphal mats formed by ectomycorrhizal (EcM) fungi are prominent features in Douglas-fir (Pseudotsuga menziesii) forest soils and have been estimated to cover up to 40% of the forest floor in some stands. Although previous studies have examined various aspects of EcM fungi, little is known about their associated microbial...

Abstract:: Total length and biomass of fungal mycelium in the soil of a young Douglas-fir stand in the central Oregon Coast Range were estimated over 27 months with the agar-film technique. In a second study, phenology and taxonomy of hypogeous (belowground) sporocarps were studied over 32 months in a nearby, young...

Abstract:: The influence of vesicular-arbuscular mycorrhizae (VAM) on populations of general taxonomic and functional groups of naturally-occurring rhizosphere bacteria and actinomycetes associated with roots of sweet corn (Zea mays var. rugosa) and subterranean clover (Trifolium subterraneum L.) was assayed using selective media. Sporangial production by Phytophthora cinnamomi was also used as...
