Simulating short-term light responses of photosynthesis and water use efficiency in sweet sorghum under varying temperature and CO₂ conditions.

ABSTRACT: Climate change, characterized by rising atmospheric CO₂ levels and temperatures, poses significant challenges to global crop production. Sweet sorghum, a prominent C₄ cereal extensively grown in arid areas, emerges as a promising candidate for sustainable bioenergy production. This study investigated the responses of photosynthesis and leaf-scale water use efficiency (WUE) to varying light intensity (I) in sweet sorghum under different temperature and CO₂ conditions. Comparative analyses were conducted between the A _n-I, g _s-I, T _r-I, WUE_i-I, and WUE_inst-I models proposed by Ye et al. and the widely utilized the non-rectangular hyperbolic (N
