My Short Summary Follows:
"Carbon fertilization can enhance yield and/or the antioxidant properties of greenhouse-grown lettuces, but results are highly dependent on the variety or cultivar evaluated."
Three-week-old lettuce seedlings were grown in ambient CO2 (~400 ppm) or elevated (~700 ppm) CO2 concentrations, under either well-watered (field capacity), or water-deficit (two-thirds of field capacity), conditions for seven weeks, in a controlled-environment setting.
Fresh weights of the elevated CO2 and water-deficit treatments were 20% higher than with ambient CO2 and well-watered treatments, for both cultivars. This measure of nutritive value was "significantly enhanced" in leaves of BRM under elevated CO2, whereas it remained unchanged in the MV cultivar.
