摘要

The recently developed virtual plant modelling approach has strongly increased the potential of model applications in crop sciences. Virtual plants are based on a new modelling concept and are generated in a 3-dimensional (3D) virtual space. The technique facilitates the incorporation of 3D environmental effects on plant growth and development. The methodology to generate virtual plants is described for Arabidopsis thaliana flower mutants and for Chrysanthemum plants. The profiling method was used to create 3D images of existing plants by merging 2D digital pictures of the plant silhouette to a 3D object. The data from the digitized plants were used to calibrate an architectural model for Arabidopsis thaliana, based on the L-systems algorithm. This architectural model was able to simulate the morphological differences between a number of plant genotypes. On the basis of L-systems, a prototype architectural model was made for Chrysanthemum. The L-system calculated temperature driven growth and light interception on the basis of radiosity. A method is presented to link this 3D model to a physiological growth model to incorporate effects of carbon dynamics. The first results show that the combined strength of both models may help to understand and visualize plant growth and appearance.
