Surfing the Hyperbola Equations of the Steady-State Farquhar-von Caemmerer-Berry C₃ Leaf Photosynthesis Model: What Can a Theoretical Analysis of Their Oblique Asymptotes and Transition Points Tell Us?

ABSTRACT: The asymptotes and transition points of the net CO₂ assimilation (A/C_i) rate curves of the steady-state Farquhar-von Caemmerer-Berry (FvCB) model for leaf photosynthesis of C₃ plants are examined in a theoretical study, which begins from the exploration of the standard equations of hyperbolae after rotating the coordinate system. The analysis of the A/C_i quadratic equations of the three limitation states of the FvCB model-abbreviated as A_c, A_j and A_p-allows us to conclude that their oblique asymptotes have a common slope that depends only on the mesophyll conductance to CO₂ diffusion (g_m). The limiting values for the transition points between any two states of the three limitation states c, j
