abstract = {Root system traits are important in view of current
challenges such as sustainable crop production with reduced
fertilizer input or in resource limited environments. We
present a novel approach for recovering root architectural
parameters based on image analysis techniques. It is based
on a graph representation of the segmented and skeletonised
image of the root system, where individual roots are tracked
in a fully-automated way. Using a dynamic root architecture
model for deciding whether a specific path in the graph is
likely to represent a root helps to distinguish root
overlaps from branches and favours the analysis of root
development over a sequence of images. After the root
tracking step, global traits such as topological
characteristics as well as root architectural parameters are
computed. Analysis of neutron radiographic root system
images of Lupinus albus grown in mesocosms filled with sandy
soil results in a set of root architectural parameters. They
are used to simulate the dynamic development of the root
system and to compute the corresponding root length
densities in the mesocosm. The graph representation of the
root system provides global information about connectivity
inside the graph. The underlying root growth model helps to
decide which path inside the graph is most likely for a
given root. This facilitates the systematic investigation of
root architectural traits in particular with respect to
parametrisation of dynamic root architecture models},
