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 objective of the study was to evaluate the ability of ericaceous plants and overstory conifers to share compatible mycorrhizal fungi in order to assess potential mycorrhizal linkages. Ericoid mycorrhizal fungi were examined in Gaultheria and Rhododendron to assess their assumed presence in soils of the Pacific Northwestern region of the United States. Nine ectomycorrhizal types were recognized on the conifers and two on the Ericaceae. All nine ectomycorrhizal types occurred on both conifer species, and the two ectomycorrhizal types on the ericaceous hosts resembled types associated with the conifer hosts. Ectomycorrhizal fungi occurred on all the conifer seedlings and in trace amounts on 26% of the ericaceous seedlings in the study. Ericoid mycorrhiza developed on all the ericaceous seedlings.
在俄勒冈海岸山脉的三片年轻的人工管理花旗松林中采集土壤，将冬绿树、花旗松、大叶杜鹃和异叶铁杉的幼苗种植于温室中的这些土壤里。该研究的目的是评估杜鹃花科植物和上层针叶树共享兼容菌根真菌的能力，以便评估潜在的菌根联系。对冬绿树和杜鹃中的类菌根真菌进行了检测，以评估它们在美国太平洋西北地区土壤中的假定存在情况。在针叶树上识别出了9种外生菌根类型，在杜鹃花科植物上识别出了2种。所有9种外生菌根类型都出现在两种针叶树物种上，杜鹃花科宿主上的两种外生菌根类型与针叶树宿主相关的类型相似。在该研究中，外生菌根真菌出现在所有针叶树幼苗上，在26%的杜鹃花科幼苗上有微量出现。所有杜鹃花科幼苗上都形成了类菌根。
