Abstract:

In order to simulate the actual plant growth effectively and objectively, a simulation of plant growth regulated by IAA （indoleaeetic acid） was carried out integrated with considering the mutual impacts between exterior morphology, physiological mechanism and environment elements in this work. A model based on the open L system was constructed to demonstrate the adjusting role of IAA on plant growth. The model expressed the actual plant growth and 
development status affected by internal and external factors, and proved that the dynamic plant growth was controllable.

Key words: virtual plant , indoleaeetic acid , open L system , environment

摘要：

为有效地模拟真实植物的生长过程，综合考虑植物外部形态、生理机制和环境因素的相互影响，基于开放L系统，对植物激素——生长素对植物生长调节作用进行建模，真实再现植物在内外因素影响下的生长发育形态，并实现植物生长的动态可控性。
