Measured gas exchange parameters upon transition from dark to high light (1800 µmol m−2 sec−1) after 30 min of dark adaptation: (a) leaf CO2 uptake rate (A); (b) intercellular CO2 concentration (Ci ); (c) stomata conductance (gs ); (d) non‐photochemical quenching (NPQ); and (e) intrinsic water‐use efficiency (iWUE). Bars represent ±1 SEMs for six plants. Leaf CO2 uptake (A) of the youngest fully expanded leaf was measured on 30‐day‐old maize B73, sugarcane CP88‐1762 and sorghum Tx430 plants with a gas exchange system (LI‐6800, LI‐COR).
