Tang et al. (2003) |
Plants grown from seed in pots with 1 kg natural topsoil and 0 mg kg-1 Cu for 24 days in ambient air (400 ppm CO2), after which one-third of the pots were exposed to air of 800 ppm CO2 and the other one-third to air of 1200 ppm CO2 for 12 additional days. The extra CO2 was only supplied from 0800 to 1100 on sunny days.
