Functional-Structural Plant Modeling

 
The Functional-Structural Plant Modeling (FSPM) approach has been developed since two decades and is presently gathering an increasing community of botanists, agronomists, foresters, ecophysiologists and modelers. Compared to the Process Based modeling approach, the FSPM paradigm allows to model explicitly the growth, branching and mortality events that built plant architecture jointly with the underlying physiological processes. By doing so, each plant organ can be located within the plant architecture with its proper age and characteristics.

In addition, modeling or digitizing the dimensions, position and orientation of plant organs permits to obtain a 3D plant representation that can be used for calculating the irradiance, the photosynthesis and the transpiration of its leaves. Finally water and carbohydrates transfers can also be simulated owing to the explicit plant topology representation.

A last step consists in putting together some of these different architectural and functional sub-models in a single model in order to account for feedback processes between physiological processes and growth.

During the meeting, different methods, sub-models, and examples of plant FSPM will be presented.

How this domain opens new prospects for both theoretical and applied studies will be discussed with the participants.
