Antioxidant enzyme activities in C. sinensis cv. Baijiguan. (A) Antioxidant enzyme activities at different leaf positions under high-light conditions. The second leaf was utilized as the control. (B) Effects of shading on POD activity. (C) Effects of shading on SOD activity. (D) Effects of shading on CAT activity. * Represents a significant difference (P < 0.05) between the control and shade treatment. ** Represents a highly significant difference (P < 0.01) between the control and shade treatment. In Panel (A), other leaf position compared to the second leaf position, and in Panels (B–D), T3d_Z compared to T3d_W and T6d_Z compared to T6d_W.
