Title: Effects of drought and shade on growth and water use of Quercus alba, Q. bicolor, Q. imbricaria and Q. palustris seedlings

Author: McCarthy, Joseph J.; Dawson, Jeffrey O.

Year: 1991

Publication: In: McCormick, Larry H.; Gottschalk, Kurt W., eds. Proceedings, 8th Central Hardwood Forest Conference; 1991 March 4-6; University Park, PA. Gen. Tech. Rep. NE-148. Radnor, PA: U.S. Department of Agriculture, Forest Service, Northeastern Forest Experiment Station: 157-178.

Abstract: Growth and water use efficiency were determined for 2-year-old white oak (Quercus alba), swamp white oak (Q. imbricaria) and pin oak (Q. palustris) seedlings grown under three shade treatments (30, 55 and 73%) and two irrigation regimes (container capacity and mild drought). With species and water regimes combined, the dry weight increment, root, stem, leaf, shoot dry weight and water use efficiency of the oaks decreased significantly as shade level increased from 30 to 73%. Shade had no effect on height increment, while shoot/root dry weight ration increased with increasing shade.
