Age-structured modelling of perennial grapevine roots (Vitis vinifera) shows woody root scaffolds are not static, with multicohort turnover shaping hydraulic uptake over decades.
- Why it matters: Root architecture models often assume permanent woody roots, missing continuous turnover and dormancy that likely govern long-term structure and function in perennial systems.
- What they did: The study extended CPlantBox to simulate decades of age-structured demography, secondary radial growth, and climate-driven dormancy, parameterised with 3D root data from young and mature grapevines plus dendrochronological root ages and coupled hydraulic properties.
- The result: The model reproduced age distributions, order-specific survival, and fine-to-structural length ratios, and simulations showed uptake and hydraulic scenarios depend strongly on root age and architecture, enabling genotype × climate analyses.
