Scanning Technology for Root and Soil Studies
March 9, 2012| |
Centre for Plant Integrative Biology (CPIB) Professor Malcolm Bennet, an expert in root biology opined that "Root architecture critically influences nutrient and water uptake. A key impediment to genetic analysis of root architecture in crops grown in soil has been the ability to image live roots. Recent advances in micro CT and RooTrak software at Nottingham now make this possible."
Micro CT and RooTrak works by stacking virtual slices through the root-bearing soil. RooTrak treats each slice as a movie frame and static roots are treated as moving objects that can be tracked. Hence, the software can tell the difference between root and water or organic elements in the soil.
Thus, this technique offers a three-dimensional detailed and accurate root architecture. The software along with an innovative micro CT-based imaging approach is planned to image the roots of wheat, and choose new varieties with optimal water and nutrient uptake efficiencies.
