In order to better explore the methods of establishing simulation models of plants and improve the efficiency of plant simulation study,a functional-structural model of a rice seedling was designed and implemented based on the formalism of Relational Growth Grammars(RGG) and the eXtended L-Systems(XL) language.The model contains an environment module of radiation,a structural model of the plant,a physiological module with basic functions(for photosynthesis,respiration and growth),and the modules of the environmental settings,which enables the model to describe the growth processes on the scale of the morphological dynamics externally as well as the physiological processes internally.The consideration of the combination of interactions between physiological processes and morphological development of the plants,and the environmental factors,makes it possible to predict and visualize the growth dynamics of the simulated plant,which was modeled with GroIMP,an open source and interactive modeling platform.The ways and the key steps to establish the main modules and sub-models of the rice simulation model were briefly introduced.With the outputs of the figures and the charts,the model was validated.It is concluded that the model can be simply modified and extended to simulate the rice model during the whole growth period.
