Table II

Osmotic potential at full turgor (π100), osmotic potential at turgor loss point (π0), relative water content at turgor loss point (RWC0) and mean bulk elastic modulus (ε) for 3 species of Eucalyptus during winter (date) and summer (date) sampling periods. Post hoc grouping was performed using Tukey’s HSD. Season significance was obtained using ANOVA and Fishers LSD tests.
