Modelling of growth, architectural dynamics and photon transfer in crop stands. Integration of process models into a 3D-model system

The main task of this project is the development of a process oriented simulation model that describes the environmentally controlled growth of individual plants and their organs, especially the interaction between the architectural dynamics and the photon transfer in the plant stand. To establish the dynamic model equations, suitable state variables, sink- and source-terms as well as the fluxes have to be defined. Based on that terms, further algorithms to aggregate the models from leaf to canopy (upscaling) will be developed. As a part of the Virtual Crop Modelling System (VCMS) and in cooperation with other sub-projects, special sub-models will be integrated into the 3D-model VICA(Virtual Canopy). To calibrate and validate the sub-models of growth and radiation transfer, 3D morphological, physiological and spectral data of single plants and of plant stands will be measured. To this aim and in cooperation with other sub-projects, measurement methods and a common data format for the 3D plant descriptions will be established and used.
