Leaf Mutiscale Variation Algorithm under Functional Structural Plant Model

This paper presents a new scheme using Functional structural plant model (FSPM) employing feedback control system (FCS) to realize the multiscale change of the physiological parameter for leaf growth. Firstly, the plant branching structures are generated by Bidimensional Hierarchical Automata (BHA) while the disturbance function is used to realize the interaction between physiological parameter and botanic growth stimulant. Secondly, the growth stimulant changes the organic details and influences the environment parameters. On the other hand, the change of environment parameters modifies the plant branching structure in return. Thirdly, the varying vein texture is synthesized by reaction-diffusion principle based on the canalization hypothesis. Finally, the three-dimension deformation of a leaf is proposed by the controllability grid bending. Simulation results show that proposed algorithm can effectively simulate the varying process of leaf texture and form by changing physiological parameter. It can well meet the requirement of dynamic displaying plant organ in virtual agricultural laboratory.
