Fig. 6. Effects of drought stress on expression of flavonoid biosynthesis key enzyme genes. A: C4H; B: 4CL; C: IFS; D: F3H; E: DFR. Shown are the means ± standard deviation (n = 3). The asterisk indicates a significant difference (p <0.05) between drought-stressed and control plants (Duncan's single-factor variance analysis).
