The ratio of leaf intercellular to ambient CO2 (chi) is modulated by stomatal conductance (g(s)). These quantities link carbon (C) assimilation with transpiration, and along with photosynthetic capacities (V-cmax and J(max)) are required to model terrestrial C uptake. We use optimization criteria based on the growth environment to generate predicted values of photosynthetic and water-use efficiency traits and test these against a unique dataset.
