Validation with simulated time-series of root system growth for different diameter classes. (a) Class 1 diameters are strongly underestimated due to the poor image resolution of fibrous roots. Indeed, an increase over time is also indicated in the analysis, but the results do not reflect the absolute values of the simulation. (b, c) Class 2 and 3 diameters display a high concordance between simulation parameters and analysis results at every growth stage. (d) Class 4 diameters appear in week 10, however the analysis detects them in week 9 for the first time. This corresponds to an overestimation of class 3 diameters in the same week (c). In (e), examples of the underlying OSR models at different developmental stages are highlighted.
