In all species, these changes resulted in a highly significant ( P < 0.001) increase in the C i transition point between the Rubisco‐limited and electron transport‐limited phases of photosynthesis for plants grown under elevated CO 2 ( t (7.8) = −4.35, t (12.1) = −5.68, t (12.4) = −4.96, in Elaeocarpus , Ficus and Mallotus , respectively).
