Quantifying key model parameters for wheat leaf gas exchange

发布时间：2021-09-17 12:51

　　The maximum carboxylation rate of Rubisco(V_cmax) and maximum rate of electron transport(J_max) for the biochemical photosynthetic model, and the slope（m） of the Ball-Berry stomatal conductance model influence gas exchange estimates between plants and the atmosphere. However, there is limited data on the variation of these three parameters for annual crops under different environmental conditions. Gas exchange measurements of light and CO₂ response curves on leaves...
