Abstract

Using models of frangipani, cotton and birch plants, this paper shows how physiology can be included in structural plant models through local plant component resource modelling, crop level modelling and canonical mathematical modelling at the level of the individual plant. These simulations are more than just pictorial representations of these plants, and more than just three-dimensional structural representations changing over time. They respond to their environment as they grow, which is achieved by including aspects of physiology in the models. However, they do not require detailed and complex quantitative understanding of the individual plant's physiology. This paper demonstrates the possibility of constructing such adaptive virtual plant simulations, with environmentally sensitive complex emergent structure, by modelling physiology in simple, yet effective ways.
