in a vice. The ψ s of the sap was measured at 20 °C by psychrometers (C-52 sample chambers; Wescor, Logan, UT). Values of ψ s were averages of two measurements from each sample. Leaf turgor pressure (ψ p ) was calculated as the difference between ψ

The P-V curve has been used to estimate symplastic water volume, ψ S , pressure potential, turgor loss point, and elastic modulus of plant cells, tissue, and organs ( Holbrook and Sinclair, 1992 ; Richter, 1978 ; Scholander et al., 1965 ; Tyree

0.15 L·L −1 or less. Reduced leaf expansion is an easily observed symptom of water stress, because turgor pressure is the driving force for cell elongation ( Taiz and Zeiger, 2010 ). Turgor pressure, in turn, typically decreases with decreasing

( Zwack and Graves, 1998 ). We noticed that predawn leaf water potentials decreased rapidly with substrate moisture content after the moisture content decreased to a critical point. This critical substrate moisture content seemed to be around 15% for all
