(a) Gibberellin A1 (GA₁), (b) gibberellin A3 (GA₃), (c) gibberellin A4 (GA₄), and (d) total gibberellin (GAs) concentrations in leaves of pepper plants of the commercial variety “Gacela F1” either non-grafted (G) or grafted onto the commercial rootstocks Creonte (G/C), Atlante (G/A), and Terrano (T/A), and cultivated under control (0 mM NaCl) and salinity (35 mM NaCl) conditions. Bars show the means of five plants ± standard error. Different capital letters indicate significant differences due to the salt treatment while different small letters show significant differences among graft combinations according to Tukey’s test (p ≤ 0.05).
