In many scenarios, water availability plays a determinant role in plant growth. Current functional-structural plant models (FSPs) mainly focus on plant-carbon relations and largely disregard the importance of plant-water relations.
Coussement et al. adapted an existing water-flow and a storage model was made was for integration into FSPs. It applies explanatory concepts of water flow, water potential and turgor on the scale of individual plant organs with a direct link to plant growth in 3D. The model is applicable to any plant architecture and allows visual exploration of the dynamics in plant organ water content and growth.
