摘要：
The objective of this paper was to develop a morphological parameter-based root geometric model of rice and realize the dynamic three-dimensional visualization of rice roots under different growth conditions. The three-dimensional display model of single root of rice was developed by analyzing the change patterns of root-tip growth with development progress, including the sub-models of initial location and growth orientation of root node, and the spatial elongation curve of root axis. By integrating the topological structure of rice root, the whole three-dimensional visualization model of rice root was established using GDD as driving factor, including the sub-models of the initial emergence time and location, initial extension angle, elongation rate and spatial distribution of adventitious root in rice. Finally, by integrating the sub-modules of visualization display, scene control, human-machine interface and database management on the platform of Visual C++, the three-dimensional visualization system of rice root was established, and the three-dimensional morphology of rice root under different growth conditions was simulated based on this system. These results could lay a foundation for development of visual rice growth system, and for reference to visualization studies in other crops.
