Figure 1: Plants were exposed to elevated (1500 ppm) ambient (400 ppm)
or low (150 ppm) CO2 for 30 h, including an 8-hour dark
period during the typical night hours, with A/Cicurves performed every 2.5 hours. The A/Ci curves
were fit according to Gregory et al. , (2021) and the three
primary fit parameters, Vcmax , J , andTPU relative to an A/Ci curve run before
treatment began are plotted.
