Morphological differences between androgenic lines differing in leaf apex shape at late vegetative stage and reproductive stage. a Erect leaf of acute leaf apex (left) vs. droopy leaves of attenuate leaf apex (right) of androgenic plants at early vegetative stage. Scale = 6 cm. The auricles and ligules observed in the lines are shown in the respective insets. b twisted nature of leaf blades of lines with acute leaf apex,. Scale = 1.7 cm. c non-twisted nature of leaf blades in lines with attenuate leaf apex, Scale = 1.7 cm. d Spikelet on acute (left) and attenuate leaf apex (right) lines, Scale = 1.5 mm. e Deformed lodicule of acute leaf apex line, Scale = 0.75 mm. f Normal swollen lodicule of attenuate leaf apex line, Scale = 0.75 mm. g Pistils of lines with acute leaf apex (yellow arrow) and attenuate leaf apex (red arrow) lines, Scale = 0.5 mm. h Pollen grains in acute leaf apex lines, Scale = 0.39 μm. I Pollen grains in attenuate leaf apex lines, Scale = 0.39 μm
