基于双尺度自动机模型的植物花序模拟

以几种典型花序的模拟为例,探讨了应用双尺度自动机模型模拟花序的方法。通过在双尺度自动机模型中引入“同步生长机制”和“重复生长机制”,能够模拟所有植物学中给出的花序类型。并通过应用“生长延时机制”,实现了“向顶开花”和“向基开花”两种开花顺序的模拟,避免了L系统用成花信号控制的缺点,最后通过与L系统的比较,证明了该方法简单实用。

Simulation of Inflorescences Using Dual-Scale Automaton Model

Simulation of inflorescences is an important part of "virtual plant growth". The past works about simulation of inflorescences focus mainly on how to generate inflorescences by "L system". However, the productions of L system are difficult to understand and implement since it is described with rule based language, and especially it needs too many parameters in simulating inflorescence development and flowering sequences. "Dual scale automaton model" is a plant growth model based on plant growth mechanisms, which is easy to understand and implement in programming. In this paper, the method of simulating inflorescence using dual scale automaton model is discussed. The dual scale automaton model is improved by introducing the rule of synchronization development, mechanism of reiteration and delay law of plant growth from the viewpoints of botany,which make it possible to generate almost all types of the inflorescences defined by botanists, and to simulate acropetal and basipetal flowering sequences. Several examples of simulation of typical inflorescences are given for explaining the theory. The improved model is demonstrated a simpler but more effective method in simulating inflorescences in comparison with L system.
