Leaf Water Potentials of Perennial Grasses—Leaf Press and Pressure Chamber Evaluation

The leaf water potentials of blue grama [Bouteloua gracilis (H.B.K.) Griffiths] and western wheatgrass (Agropyron smithii Rydb.) transplants were measured using a pressure chamber and a leaf press. Combined water potentials for both species ranged from -5.34 to -26.05 bars for the pressure chamber and -5.52 to -16.24 bars for the leaf press. Trends between the to methods were more consistent for blue grama. Generally, large increases in leaf water potential measured with the pressure chamber were measured as small changes with the leaf press.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
