Management impacts on the ectomycorrhizal associations of Pseudotsuga menziesii var. menziesii seedlings : field and greenhouse bioassays

Creator:

Pilz, David P.

Abstract:

Field and greenhouse bioassays were used to compare the mycorrhizal associations of Douglas-fir seedlings from undisturbed forests, and nonburned and burned portions of clearcuts on three Sites in the west-central Cascades of Oregon. Field soil transfers and greenhouse soil pasteurization and reinoculation were used to investigate soil biology and inoculum...
