Abstract

One-year-old red ash (Fraxinus pennsylvanica) seedlings inoculated with the endomycorrhizal fungus Glomus intraradices were outplanted in abandoned fields and in clearcuts. Survival and growth of seedlings were measured for four years. Mean total heights, mean collar diameters, and mortality did not differ significantly between inoculated plants and the controls or between field-grown and clearcut-grown seedlings. However, the variance components of total height and diameter associated with sites differed significantly from zero. Growth in all cases seemed related to soil wetness. Key words: Glomus intraradices, Fraxinus pennsylvanica, afforestation
