GROWSCREEN-Root

Measuring the architecture of the root system

growscreenroot250_jpg

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.
