Model description
Ecomeristem models plant growth at the organ level in the crop stand. It aims to simulate phenotype variability and plasticity within a given species depending on the genotypic (G) and environmental (E: water, light and temperature) regulation of C supply and demand and thus of C source–sink relationships. It represents the crop stand as a population of average plants described by their topology and morphology (organ size and dry weight) with a given homogenous planting density. The topology and morphology are dynamically simulated as the result of G × E interactions. This model was initially created for rice vegetative vigour.
