Fig. 6 From:Photosynthesis acclimation under severely fluctuating light conditions allows faster growth of diatoms compared with dinoflagellates Photosynthetic parameters for PSII,a,cande: under mFL after the addition of 1 min of bright light (dark yellow, 800 μmol photons m− 2 s− 1) to every 5 min of low light (white, 80 μmol photons m− 2 s− 1); andb,dandf: under sFL after the addition of 1 min of stronger light (bright yellow, 2000 μmol photons m− 2 s− 1) to every 5 min of low light (gray, 20 μmol photons m− 2 s− 1). The values shown are the means of at least three biological replicates.aandb: NPQ, non-photochemical quenching;candd: Y(II), the actual conversion efficiency of light energy of PSII;eandf: 1 - qL, PQ redox state Back to article page
