Fig. 5From: Effects of red and blue light on leaf anatomy, CO2 assimilation and the photosynthetic electron transport capacity of sweet pepper (Capsicum annuum L.) seedlingsEffects of different light treatments on chlorophyll fluorescence parameters: (a) Fv/Fm, maximum photochemical efficiency of PSII; (b) ΦPSII, actual PSII photochemical efficiency; (c) F’v/F’m, maximum photochemical efficiency of PSII under light adaptation of sweet pepper seedlings at 28 day after treatment. Data are presented as means ± SE, n = 3. Different letters indicate significant differences between values (p < 0.05). W, white light; R, monochromatic R light; B, monochromatic B light; RB, mixed R and B light of 3:1Back to article page
