Dynamics of photosynthetic rate (A) and stomatal conductance (g_s) at the leaf level in the controlled fluctuating light environments in four C₃ and five C₄ species. (A–H) four C₃ and (I–R) five C₄ species. Light intensity was alternately changed between low (100 μmol m⁻² s⁻¹ PPFD, gray area) and high (1,000 μmol m⁻² s⁻¹ PPFD, white area) at 15-min intervals for a total of 75 min. Red and blue lines represent plants grown under HN and LN conditions, respectively. Data are the mean ± se (n = 4).
