3D and dynamic models of wheat and pea were used to study light partitioning in virtual wheatpea mixtures. Our results showed that architectural parameters defined at plant scale (e.g. branches, internode length) significantly affect the interception of light by each component species. The modifications performed on the architectural parameters of both models led to asymmetric variations of light partitioning.
