The mycorrhizal status of boreal plants: species from northeastern Ontario

摘要

Twenty-nine species of vascular plants commonly occurring in the Boreal Forest Region of northeastern Ontario were examined for the presence of mycorrhizae. Four species were ectomycontiizal, 4 both endo- and ecto-mycorrhizal, and 15 endomycorrhizal. Among the Ericaceae, one had arbutoid mycorrhizae and five ericoid mycorrhizae. The distribution ofCenococcum geophilumamong the ectomycorrhizal and arbutoid plants is compared. Selected findings are discussed in relation to reports in the literature.
