Supplementary Light Source Affects Growth, Metabolism, and Physiology of Adenophora triphylla (Thunb.) A.DC. Seedlings

Figure 7

Activities of SOD (a), CAT (b), and GPX (c) in A. triphylla leaves grown under different supplementary light sources: HPS, high pressure sodium; MH, metal halide; FR, far-red; LED-w, white (red: green: blue = 2:4:3) light-emitting diodes; and LED-mix, mixed (red: green: blue = 4:1:4) light-emitting diodes. SOD, sodium dismutase; CAT, catalase; and GPX, guaiacol peroxidase. Data are presented as the mean ± standard error of mean (n = 3). Different letters (A and B) indicate significant differences (p < 0.05) among treatments.
