Table 2. Plant water relations obtained from P-V curves. Osmotic potential at saturation (Ψπ_sat), relative water content at turgor loss point (RWC_tlp), Osmotic potential at turgor loss point (Ψπ_tlp) and modulus of elasticity (e) of Eucalyptus globulus, after drought hardening regimes (-0.2, -1.3 and -2.4 MPa). Values are means ± 1 SE, (n = 3). Means with different letters are significantly different (P ≤ 0.05).
