Figure 5.

Model parameters were determined from A_n -C_i data. Carbon dioxide compensation point (Γ, A–C), maximum ribulose-1, 5-bisphosphate carboxylase/oxygenase (Rubisco) carboxylation rate (V_{c, max} , D–F), and potential light saturated electron transport rate (J_max , G–I) under e[CO₂] and warming at the tillering, anthesis, and grain-filling stages of SH (Shishoubaimao), HJ (Hejiang 19), and LJ (Longjing 31). Data are means ± standard errors (n = 3). The data of (J_max /V_{c, max} , J–L) radio is the average means ± standard errors (n = 9) at three stages in each cultivar. Different letters indicate significant differences between mean values at P < 0.05 level.
