Fig 6. Two performance indices in muskmelon seedlings.
A. Performance index on an absorption basis (PIABS). B. Proton motor force on an absorption basis (DFABS). Control, plants grown in medium only; CG, medium with leaf spraying with GABA; S, nutrient medium with complex neutral and alkali salt; SG, medium with both complex neutral and alkali salt and leaf spraying with GABA. Data represent the mean ± SE of three independent experiments (n = 3). Different letters indicate significant differences between treatments (p < 0.05).
