Simulation of Jatropha curcas L. root in response to salt stress based on 3D visualization

In order to explore the effects of salt stress on root configuration. This research take the root of Jatropha curcas L as object, a method was proposed that was to statistically analysis root space distribution by Otsu and based on it's morphological and growing characteristic after partitioning root image. Using image processing library to obtain the spatial distribution statistical matrix by the Python language programming, 3D visualization root model was established for Jatropha curcas L with SimRoot root structure model as geometric prototype by using the Visual C++ and OpenAlea model under different salt levels. The results show that this method can scientifically simulate the influence salt stress on Jatropha curcas L root topological.
