Antioxidant enzyme activity of Polygonatum sibiricum. (A) Superoxide dismutase (SOD) activity in the aboveground and underground parts; (B) Peroxidase (POD) activity in the aboveground and underground parts; (C) Catalase (CAT) activity in aboveground and underground parts. Each value represents the mean ± standard deviation of three independent experiments. Different letters above the bars represent significant differences (p < 0.05).
