Values are Means with SE or 95% CI in parentheses. σ, slope of Ψl vs Ψpd, reflecting the degree of anisohydry: σ > 1, more anisohydric; σ < 1, more isohydric (see Martínez-Vilalta et al., 2014). Values of height and basal diameter (n = 21–30) and total dry mass (n = 6–9) represent values at the beginning of the experiment. Estimated P50 was derived from hydraulic vulnerability curves conducted at the beginning (n = 13–25). Achieved Ψxylem (n = 3–4) and PLC (n = 3–4) represent xylem water potential and PLC at peak drought stress, respectively. NA, data is not available.
