List of presentations about root systems Architecture, Observations, Modelling, Simulation and Exploration.

You can download them to get every informations about root-systems architecture, growth and development modelling, DigR model and AMAPstudio software environment.

In each presentation, we introduce parameters which are used to model 3D root-system architecture.

  • The values of parameters are then saved in a parameter file.
  • This parameter file will be used by DigR simulator in Xplo sofware to build a 3D root-system mockup
  • See Parameter Files section to get theses parameter files.

For each parameter of DigR model described in the presentations, we detail its meaning and how to use it.

NOTE : if you want to download these files, do “right click” with mouse. By default, they will be opened in a new window (pdf format).

Root system architecture
