3D phytomer-based geometric modelling method for plants-the case of maize

Area of Science:

• Plant Sciences
• Computer Graphics
• Computational Biology

Background:

• Geometric plant modeling is essential for in silico plants.
• Current methods simplify morphology, limiting cultivar differentiation and applications in crop breeding.
• Accurate geometric models are needed for detailed plant analysis.

Purpose of the Study:

• To develop a 3D phytomer-based geometric modeling method for maize (Zea Mays).
• To enable differentiation of cultivars based on morphological, structural, and functional features.
• To provide a robust method for constructing detailed 3D plant and population models.

Main Methods:

• Developed a 3D phytomer-based geometric modeling approach.
• Specified conversion methods between skeleton and mesh models for 3D phytomers.
• Assembled 3D phytomers to model maize shoots and populations.

Main Results:

• Successfully constructed 3D models of maize plants and populations efficiently.
• Demonstrated the ability to show morphological, structural, and functional differences among four maize cultivars.
• Achieved automatic geometric modeling through standardized 3D phytomer descriptions.

Conclusions:

• The proposed method offers efficient and detailed 3D geometric modeling of maize.
• It provides a theoretical and technical foundation for in silico plant research and applications.
• This approach enhances the utility of plant modeling in crop breeding and management.
