Effects of Defoliation and Antitranspirant Treatments on Transplant Response of Scarlet Oak, Green Ash and Turkish Hazelnut    (View PDF)

J. Roger Harris and Nina L. Bassuk

Abstract: Combinations of defoliation and MoisturinŽ, a film antitranspirant, were applied to recently transplanted Quercus coccinea (scarlet oak) trees in August and to Fraxinus pennsylvanica (green ash) and Corylus colurna (Turkish hazelnut) trees in the late summer and fall of 1992.For scarlet oak trees, survival was poorfor all treatments. MoisturinŽtreatments aided survival and spring shoot extension for green ash trees transplanted in late summer, but showed no effect on later dates. Defoliation was detrimental to survival of green ash trees at all transplanting dates. Root regeneration did not occur on transplanted green ash or Turkish hazelnut before spring bud break.
