Abstract: Stomatal conductance (Gs) that controls CO2 diffusive fluxes (i.e. photosynthesis) between atmosphere and plants is one of the key factors to quantify drought impact. We aim to test the hypothesis that “variance of Gs in croplands would be dominantly explained by the atmospheric dryness indicated by VPD rather than by soil moisture deficit”.
