pv‐curve analysis and xylem hydraulic parameters of Vaccinium myrtillus in May, August and October. Osmotic potential at saturation (Ψo; MPa), turgor loss point (Ψtlp; MPa), cell wall elasticity (aela; dimensionless), xylem water potential at 12, 50 and 88% loss of xylem conductivity (ΨPLC12, ΨPLC50, ΨPLC88; MPa) of shoots measured in Innsbruck, Tyrol are given. Mean ± se, different letters indicate significant differences between sampling dates, P ≤ 0.05
