Figure 1

Pre-dawn leaf water potential ((AD); ΨL; MPa), and leaf osmotic potential ((EH); Ψπ; MPa) of eight scion/rootstock combinations (RL: Rangpur lime; SM: Sunki Maravilha mandarin; VO: Valencia orange; TAL: Tahiti acid lime), under three different water availability conditions: control: ΨL ≤ 0.5 (white bars); severe drought stress: ΨL ≥ 2.0 (black bars); and 48-h rehydration (gray bars). Values are averages ± standard errors (n = 3). Different uppercase letters indicate significant differences between combinations, and different lowercase letters indicate significant differences within the same combination, according to the Scott-Knott test (p < 0.05).
