Stomatal conductance versus foliar ABA (A), JA (B), OPDA (C), and JA-Ile (D) concentrations in wild-type (WT) self-grafts (filled circles), def-1 self-grafts (open triangles), and reciprocal graft (scion/rootstock) combinations (WT/def-1, open circles; and def-1/WT, filled triangles). Correlations between hormone concentration and stomatal conductance reported (r² and P-values) for WT scions (dashed lines), def-1 scions (dotted lines), and def-1/WT plants (plain line). The tables summarize the significance (P-values) of hormones, scion, rootstock, and their interactions after ANOVA.
