Mycorrhiza formation and diversity in undisturbed forest and clearcut and burned areas in three forest types in Oregon

Creator:

Brainerd, Richard E.

Abstract:

A greenhouse bioassay was used to compare ectomycorrhiza formation and diversity in soils from undisturbed and clearcut and burned areas in moist mesic, moist montane and dry montane forest types representing a gradient of environmental harshness. It was hypothesized that mycorrhiza diversity decreases with increasing environmental harshness and that stability...

Occurrence of ectomycorrhizae on ericaceous and coniferous seedlings grown in soils from the Oregon Coast Range

Creator:

Smith, Jane E. (Jane Elizabeth)

Abstract:

Seedlings of Gaultheria shallon, Pseudotsuga menziesii, Rhododendron macrophyllum and Tsuga heterophylla were grown together in the greenhouse in soils from three young managed Douglas-fir forests in the Oregon Coast Range. The main objectives were 1 )to evaluate the ability of ericaceous plants and overstory conifers to share compatible mycorrhizal fungi...
