Arbuscular mycorrhizal fungi associated with Festuca species in the Canadian High Arctic
Root and soil samples from 13 collecting sites located in the Canadian High Arctic were harvested between July 18 and 29, 1991, and surveyed for root colonization and spore populations of arbuscular mycorrhizal fungi. Grasses of the genus Festuca (Festuca brachyphylla Schult. & Schult., Festuca...
