Gas exchange and growth parameters. Light-saturated photosynthesis, A sat (A), stomatal conductance, g s (B), photosynthetic water use efficiency, PWUE (C), leaf N per unit dry mass, [N]mass (D), photosynthetic nitrogen use efficiency, PNUE (E), and plant dry mass, PDM (F) of 10 grass species belonging to C3, C3–C4, and C4 (NAD-ME, PCK, NADP-ME) photosynthetic types grown at glacial (180 μl l–1, open columns) or ambient (400 μl L–1, filled columns) [CO2]. Values are means ±SE of species within each photosynthetic type.
