Rule-based integration of GreenLab into GroIMP with GUI aided parameter input

GreenLab is a functional-structural plant model that has already been applied to a number of various plant species. Plant organogenesis is described by the dual-scale automaton formalism and growth is driven by source-sink relations between plant organs. The paper presents how the formalism of GreenLab and the growth process can be translated into the rule-based language XL. Currently essential parts of the deterministic and stochastic version of the GreenLab model are included. To provide a user-friendly way for parameter input, an additional graphical user interface was developed as part of the modelling platform GroIMP. Furthermore, the features provided by GroIMP can now be coupled with GreenLab, e.g., the integrated radiation model, based on Monte Carlo ray tracing, for computing the light distribution in the canopy.
