Impact of salvianolic acid on soybean and maize plant growth parameters under normal and stress conditions 8 days post-treatment (A–T). Treatments: Cont (control), SAL (0.1 μM salvianolic acid), SAL (1 μM salvianolic acid), PEG (25% polyethylene glycol), SAL (0.1 μM salvianolic acid) + PEG (25% polyethylene glycol), and SAL (1 μM salvianolic acid) + PEG (25% polyethylene glycol). Values show the mean ± SE (n = 6) and significant differences at p < 0.05 (Tukey's test). Bars with different lowercase letters are significantly different from each other.
