Glycogen content and glycogen production after 1 week under different light intensities and CO ₂ concentrations. (a) Glycogen content; (b) glycogen production. Light intensities are 50 (white bars), 300 (gray bars), and 600 μmol photons m⁻² s⁻¹ (Black bars). Data points are mean values from three separate cultures with SD of triplicates.
