Measuring and modelling stomatal conductance and photosynthesis in mature birch in Sweden
Stomatal conductance (gs), net photosynthesis (An) and twig water potential (Ct) were measured in mature silver birch (Betula pendula) during 3 years in southern Sweden. Measurements from 2 years were used to parameterise three different gs models and measurements from a 3rd year were used to validate these models. Two different multiplicative stomatal models were used. In one of these, the gs res
