[CO2]-lowering-induced changes in photosynthetic light stage parameters and CO2 assimilation (n = 9–10). (A) EF(PSII), EF(C) and NPQ under [CO2]-lowering to 10–15 ppm. (B) ϕND, ϕNA, and A under [CO2]-lowering to 10–15 ppm. (C) EF(PSII), EF(C) and NPQ under [CO2]-lowering to 150 ppm. (D) ϕND, ϕNA, and A under [CO2]-lowering to 150 ppm. Initial [CO2] was 360 ppm. Arrow, start of [CO2]-lowering.
