FIELD TRIAL INOCULATION OF FRAXINUS-PENNSYLVANICA WITH GLOMUS INTRARADICES

One-year-old red ash (Fraxinus pennsylvanica) seedlings inoculated wit h the endomycorrhizal fungus Glomus intraradices were outplanted in ab andoned fields and in clearcuts. Survival and growth of seedlings were measured for four years. Mean total heights, mean collar diameters, a nd mortality did not differ significantly between inoculated plants an d the controls or between field-grown and clearcut-grown seedlings. Ho wever, the variance components of total height and diameter associated with sites differed significantly from zero. Growth in all cases seem ed related to soil wetness.
