Simulation of Jatropha curcas L. Root in Response to Water Stress based on 3D Visualization

Root system Visualization is one of the key researches for virtual plant. This research aimed at studying the root space structure of Jatropha curcas L. by bringing forward one kind of three-dimensional root modeling method based on geometrical model such as morphological characteristics and growth characteristic under different watering treatments. To realize three-dimensional shape reconstruction and visualization of simulation for root structure of Jatropha curcas L., the paper takes the Lynch's SimRoot configuration model as geometry model according to the root geometric topology information of Jatropha curcas L.. Results show that compared with water stress factor which is 0.9, the root space structure of Jatropha curcas L. is better, dry matter mass and water use efficiency were significantly higher when water stress coefficient is 0.7. The results provide a reasonable basis for irrigation in the energy plants Jatropha curcas L.
