Images of diseased and healthy florets in the spikelets of wheat cultivars using phase contrast X-ray imaging at 4 days after inoculation with FHB. The spikelets were kept inside a 18 mm diameter falcon tube and X-ray images were recorded at 18 keV using a 8.75 μm resolution detector. Brackets indicate the imaged part of the wheat spike. Scale bars indicate 1 mm.
