Table 1. Biochemical parameters measured at local ambient (31°C) and elevated (38°C) temperatures, and water-use parameters of the species for which photosynthesis was measured with VPD control. Maximum rates of RuBP carboxylation (Vcmax) and RuBP regeneration (Jmax) ± SEM (n = 2), the mean temperature during the measurements, their ratio, the relative limitation to PN by stomatal diffusion (Ls) and biochemical capacity (Lb), and the stomatal slope parameter, g1.
