Simulation of Plant Growth and Development under Control of IAA

In order to simulate the actual plant growth effectively and objectively,a simulation of plant growth regulated by IAA(indoleacetic 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.
