Abstract

Stem diameter variations are generally modelled based on the time lag between transpiration and root water uptake. However, small differences in endogenous osmotic regulation of the storage tissue can result in significant changes in stem diameter variation. This endogenous control needs to be taken into account in functional-structural plant models to accurately predict growth.
