The leaf pressure–volume curve (PV) parameters of well-watered (WW), transient water deficit (TD), and sustained water deficit (SD) vines after the acclimation period: osmotic potential at full turgor (π 100), mean bulk modulus of elasticity (ε), water potential at turgor loss point (ΨTLP), and relative water content at turgor loss point (RWCTLP)
| Treatment | π 100 (MPa) | ε (MPa) | ΨTLP (MPa) | RWCTLP (%) |
|---|---|---|---|---|
| WW | −1.02 ± 0.03a | 6.07 ± 0.55a | −1.08 ± 0.03b | 92.06 ± 0.90a |
| TD | −1.07 ± 0.04a | 8.16 ± 0.78a | −1.17 ± 0.04ab | 90.91 ± 1.24a |
| SD | −1.10 ± 0.05a | 7.17 ± 0.71a | −1.31 ± 0.06a | 88.21 ± 2.68a |
Values are mean ± SE (n = 9). Different letters within a column indicate significant differences between treatments (P < 0.05) by Tukey Honest Significant Difference (HSD) test
