Histocytological analysis of spikelets hulls in NIP and Oat-like rice. a and b longitudinal sections at the middle of lemma in spikelets of NIP (a) and Oat-like rice (b). c Comparisons of cell length between NIP and Oat-like rice in the longitudinal sections at the middle of lemmas and paleae in spikelets. Arrows in a and b indicate parenchyma cells used for statistical analysis of cell length in (c). Bars: (a and b) 200 μm. Data presented are mean values± SDs [n = 27 replicates in c.]. Student’s t-test: ***p < 0.001
