Seedling growth and survival studies

UNDER this title, Bain1 describes experimental investigations on mycorrhizal relationships in Vaccinium macrocarpon, Ait., V. canadense, Kalm., and two ericaceous species, reviewing and criticizing the conclusions of earlier observers in the light of his own results. In so far as the latter relate to Vaccinium macrocarpon, they may be summarized as follows. A fungus, specifically distinct from those associated with the other species studied, was isolated from roots of the cranberry, Vaccinium macrocarpon. Identity of this fungus with that forming mycorrhizal complexes in the root cells of the host was established by inoculation of the mycelium into pure cultures of cranberry seedlings growing in nutrient agar and in ‘artificial soil’ composed of cork and sand.
