Non-invasive imaging of plant roots in different soils using magnetic resonance imaging (MRI)Daniel Pflugfelder, Ralf Metzner, Dagmar van Dusschoten, Rüdiger Reichel, Siegfried Jahnke, Robert KollerPlant Methods, 2017 View paper
Barley (Hordeum vulgare L. var Barke) plants (N=4) were cultivated in seven different substrates as detailed in the file ‘PlantIDs.xlsx’. Three weeks after sowing, the plant roots were imaged using MRI and subsequently harvested, scanned and analysed with WinRhizo. Both 3D MRI data and corresponding scanned images of the excavated roots are supplied. MRI acquisition parameters: 4.7T MRI equipped with a Varian console; Sequence: Spin Echo Multi-Slice (SEMS), TR=2850ms, Bandwidth BW=156kHz, Echo Time TE=9ms, two averages. Resolution: 0.5x0.5x1.0mm3. The 3D MRI data is supplied in the Nifti-file format, consisting of a header (*.hdr) and a data file (*.img). Furthermore, for each plant a maximum intensity projection is added as a preview image (*.tif).
