Development of a novel semi-hydroponic phenotyping system for studying root architecture.

A semi-hydroponic bin system was developed to provide an efficient phenotyping platform for studying root architecture. The system was designed to accommodate a large number of plants in a small area for screening genotypes. It was constructed using inexpensive and easily obtained materials: 240L plastic mobile bins, clear acrylic panels covered with black calico cloth and a controlled watering system.
