Effects of LaCl₃, JAMe, and JA synthesis inhibitors on baicalin production in S. baicalensis seedlings. 1 Control, 2 LaCl₃, 3 LaCl₃ + SHAM, 4 LaCl₃ + PrGall, 5 JAMe, 6 JAMe + SHAM S. baicalensis seedlings were treated with LaCl₃ (100 mg/L) and JAMe (10⁻⁵ mol/L). SHAM (100 μmol/L) and PrGall (100 μmol/L) were added 45 min before the treatment with LaCl₃ or JAMe. The control received the same volumes of vehicle solvents. Baicalin production was determined after 5 days. Vertical bars represent the means ± SD (n = 6). Means with asterisks indicate significant differences at p < 0.05
