The installation is a unique system fully dedicated to measure dynamic changes in structural and functional traits of whole root architecture in 3D in soil filled pots, in situ. The method yields information on root traits: mass, length, diameter, tip number, branching angles and spatial distribution. Plants are grown in tubes of 8.1 cm inner diameter and 20-40 cm height handled by a robot. The capacity of automated measurement is ca. 20 plants per day (scan time 20 minutes) and can be repeatedly measured for the respective scientific question (e.g. every day or week) on diverse root systems.
