Visual modeling and simulation of plant growth based on plant functional-structural mutual feedback mechanism

To obtain a general method for visually modeling and simulating plant growth, this article reviewed the research on functional-structural model for plant growth at first. And then the modeling process of plant growth according to the structural-functional mutual feedback mechanism was summarized. The key techniques used in the modeling process, including the morphogenetic model, in combination of the functional model and the structural model, visualization model, and validity of the plant growth model, were introduced and discussed in detail. Finally, a real crop structural-functional growth model was presented as an example. The results show that the model of crop growth built based on the plant structural-functional mutual feedback mechanism, can visually simulate the status of plant growth and development under different environmental factors. Furthermore, it can also be used in the fields of cultivating ideal plant structure, estimating yield of crop groups, and cultivation management, etc.
