Note: k ttot, hydraulic conductivity related to unit cross section of the shoot; k tcond, hydraulic conductivity related to the sum of conduit areas in that cross section; d h, hydraulic diameter of the conduits; P 50, xylem water potential causing 50% loss of hydraulic conductivity by embolism. Species with the same lower-case letter do not differ significantly in a given trait (GLM univariate ANOVAs with post hoc Sidak test, if no deviation from homogeneity
of variances [Levene test] or from homoscedasticity; and Kruskal–Wallis [KW] tests in cases of significant deviations from homogeneity of variances or from homoscedasticity); p <0.05. Means ±1 SE.(Partial) η 2, effect sizes of (ANOVA or) KW tests.
aOnly one value for this species.
