↵z Am = American; U = ‘Urban’, P = ‘Prospector’, H = ‘Homestead’.
↵y Means within a column with any identical letters are not significantly different by LSD, 0.05 level.
↵x Average height of trees 6 years after inoculation was less than average pre-inoculation height because of the high degree (81%) of dieback after inoculation during these 6 years. Trees did not grow in height enough to make up for the loss of crown due to Dutch elm disease.
