This paper discusses the use of topological image

analysis to derive characteristics needed in plant phenotyping.

Due to certain features of root systems (deformation over time,

overlaps of branches in a 2D image of the root system) a topolog-

ical analysis is needed to correctly derive these characteristics.

The advantages of such a topological analysis are highlighted

in this paper and root phenotyping is presented as a new

application for computational topology. Characteristics used in

plant phenotyping that can be derived from root images using

methods of topological image analysis are further presented. A

Reeb graph based representation of root images is shown as

an example for such a topological analysis. Based on a graph

representation a new, normalised representation of root images

is introduced.
