Physiological conditions of rootstocks during water stress experiment. Volumetric soil water content evaluated throughout the progression of the drought stress experiment of water stress group (a) and of control group (b). Values represent average measurements ± SE of twelve replicates (WS) and six replicates (WW). Data were analysed using one-way ANOVA with LSD post-hoc test, and letters indicate significant differences between genotypes on the same day at p < 0.05. Stomatal conductance of water stressed (WS) and well watered (WW) 101.14Mgt (c), 110R (d), RGM (e) and SO4 (f) throughout the experiment. Values represent average measurements ± SE, n = 12 (WW) and n = 24 (WS). Significant differences between treatments on the same day were tested with Mann-Whitney U test, and asterisks indicate significantly different values at p ≤ 0.05 (*), p ≤ 0.01 (**), and p ≤ 0.001 (***).
