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.
