Photosynthesis of the sixth fully-expanded leaf from the top of well watered and fertilized plants grown for 500 days in 20-cm pots filled with a 2:2:1 mix of sand/perlite/promix in greenhouses, but subsequently transferred to a controlled environment chamber for short-term assessments of net photosynthesis at a variety of atmospheric CO2 concentrations, including 370 and 680 ppm
