Histological comparison of spikelet hulls between WYJ30 and two OE lines. a Grain sizes of WYJ30, WYJ30-OE1 and WYJ30-OE2. Scale bar, 1 cm. b Spikelet hulls of WYJ30, WYJ30-OE1 and WYJ30-OE2. Scale bar, 5 mm. c Cross-sections of the middle parts of the spikelet hulls (marked by white dashed lines in b) of WYJ30 and the OE lines. Scale bar, 500 μm. Magnified views of the red boxed areas are shown on the right. Scale bar, 50 μm. d Cell area and e cell number in the outer parenchyma layer of the spikelet hulls of WYJ30 and the OE lines. f Scanning electron micrographs of the lemma cells of WYJ30 and the OE lines. Scale bar, 100 μm. g Cell lengths, h cell widths and i longitudinal cell numbers of the WYJ30 and OE lines. The data are given as the mean ± SD (n ≥ 15). Different letters indicate significant differences ranked by the LSD test (P < 0.05)
