Micromorphology of glumes (a-c) and lemmas (d-f). Spikelets of cv. Dacanto (a, b, d, e) and cv. Piko (c, f) before anthesis (a, c, d, f) and after anther extrusion (b, e). Small grooves (gr) are visible in the basal parts of the glumes and lemmas already before anthesis, ra – rachilla. Scale bars in (a), (b), (d), (e) = 2000 μm, bar in (c) = 500 μm and bar in (f) = 1000 μm
