Images of control and healthy florets in the spikelets of wheat cultivars using phase contrast X-ray imaging at 10 days after inoculation with FHB. The florets were mounted on a kapton tape and X-ray images were recorded at 18 keV using a 8.75 μm resolution detector. Red inclined bar: the limit of the first fertile floret; (a): the rachilla. Scale bars indicate 1 mm.
