From: Effect of IAA on coumarins synthesis in Angelica dahurica under soil compactness stress
Changes in total coumarins content in the taproots of A. dahurica treated with different concentrations of IAA. CK(control treatment, 0 mg/L), LT(low treatment, 0.3 mg/L ),MT (medium treatment, 0.6 mg/L), HT(high treatment, 0.9 mg/L) and ST(super-high treatment, 1.2 mg/L) represent treatment groups with different concentrations of IAA, respectively. Data are the mean values (n = 3). Letters represent significant differences between treatments (p < 0.05).
