Abstract
In this study we tested and compared a multiplicative stomatal model and a coupled semi-empirical stomatal-photosynthesismodel in their ability to predict stomatal conductance to ozone (gst) using leaf-level data fromoilseed rape (Brassica napus L.) and broccoli (Brassica oleracea L. var. italica Plenck). For oilseed rape, the multiplicative model and the coupled model were able to explain 72% and 73% of the observed gst variance, respectively. For broccoli, the modelswere able to explain 53% and 51% of the observed gst variance, respectively. These results support the coupled semi-empirical stomatal-photosynthesis model as a valid alternative to the multiplicative stomatal model for O3 flux modelling, in terms of predictive performance.
