Model description

The L-Pea model is a deterministic model simulating the dynamic reconstructions of pea architecture. It is based on L-systems formalism and consists of modules for ‘vegetative development’ and ‘organ extension’. The above ground architecture is represented as a succession of phytomers that compose main stems and branches. L-Pea model is used to represent realistic/measured architectures of pea plants (resulting from the integration of environmental effects) but is not designed to reproduce the responses of plants to the environment.
