Abstract

Cottonwood cuttings planted in sandy loam and clay soils showed a sensitive control of water loss as soil moisture tension increased. Transpiration rates began decreasing at leaf water deficits of 2.5 percent in sandy loam and 4.5 percent in clay. There were no significant differences in rates per unit of leaf area or shoot dry weight between plants grown in the two soils. Terminal growth ceased when leaf water deficits reached 4 percent in sandy loam and 5 percent in clay.
