White oak, eastern redcedar, and black walnut trees exhibited distinct patterns of water relations in response to seasonal variations in soil moisture and evaporative demand. While in all three species drought periods were associated with declining leaf water potential and leaf conductance, black walnut maintained higher predawn and solar noon leaf water potential and leaf conductance (particularly late in the growing season) than did white oak or redcedar. These differences may have been related to deeper rooting and early leaf abscission in black walnut as compared to white oak and redcedar, a situation which would likely result in water conservation and greater water supply to individual leaves. Flow resistance between soil and leaves and water potential gradients between root and crown were greater in eastern redcedar than in either angiosperm species, a result largely attributable to high resistance presented by xylem tissue in which only tracheids participated in axial waterflow.
