Quantifying the response of plant water status to environmental conditions and its effect on carbon acquisition are essential for simulating plant growth and fruit composition, especially in the context of climate change. Zhu et al. present GrapevineXL, a functional-structural grapevine model that couples the dynamics of water transport from soil to leaf with gas exchange at individual leaf level.
The robust performance of this model makes it ideal for modelling climate effects on crops with complex, non-homogenous canopies and for studying plant water use behaviours. It also provides the basis for future modelling efforts elucidating the physiology and growth of individual organs in relation to water status.
