Fig. 2. Photosynthetic rate (PN) of 23-d-old wild type Arabidopsis thaliana (WT) and hy4 mutant plants grown under LEDs with ratios of RL:BL = 4:1, RL:BL:GL = 4:1:0.3, RL:BL:GL = 4:1:1, and RL:BL:GL = 3:1:2 at a light intensity of 100 μmol(photon) m–2 s–1, photoperiod of 12 h. Mean values ± SD are shown. Different letters correspond to a significant difference in values at p<0.05, n = 4.
