Measuring the architecture of the root system
GROWSCREEN-Root is a image-based software, which allows the automatic analysis of root architecture. Images of whole root systems grown in agar-filled Petri dishes are acquired with a CCD-camera. The key element of the software is the extraction of a tree model for root system.
The following parameters can be determined automatically and shown in a false-color image:
- length of primary root
- total length of lateral roots
- number of lateral roots and
- angle of branching, which represents the angle between a primary root and branched lateral roots.
The example shows data of an experiment on root growth as affected by root zone temperature
