Novel Model for Stomatal Conductance: Enhanced Accuracy Under Variable Irradiance and CO₂ in C₃ Plant Species.

ABSTRACT: This study analyzes stomatal conductance (g_sc) in Trifolium repens L., Lolium perenne L., and Triticum aestivum L. under varying environmental conditions. Light-response curves for photosynthesis (A_n-I) at 420 μmol mol^-1 CO₂ were used to determine saturating irradiance (I_sat) using a light-response model for photosynthesis, and CO₂-response curves for photosynthesis (A_n-C_i) were measured at I_sat and half I_sat for these C₃ plant species. The Ball-Woodrow-Berry (BWB) model, Medlyn model, and a new model were compared for their ability to describe the net photosynthetic rate (A_n)
