Rooting process of wheat was modeled in use of Linden Mayer system in the present study. Rooting rules along with growth cycle were concluded based on topology and biology analysis, in which the seminal roots and crown roots were treated separately. Meanwhile, some easy-to-use key parameters which are agronomical meaningful were proposed, including time, size, orientation and so on. After these preparations, code work was done in L-Py software environment. By the link to PlantGL, three dimensional root architecture models were rendered. The result shows that, the rooting rules and parameters have a good control on the dynamic rooting model and the output images exhibit realistic visualization effect.
