FIGURE 7

Ploidy status (DNA class) of the endosperm nuclei of the apical and basal spikelets of a compact-panicle rice cultivar, OR-1918, sampled on the 9 days after fertilization from the control plant and that sprayed with 6-benzylaminopurine (BAP) during the heading. (A) The endosperm nuclei ploidy status is much lesser in the caryopses of the basal spikelet compared with that in the apical spikelets. (B) Upon the BAP application, the ploidy status of the endosperm nuclei in the basal spikelets increased significantly. Reproduced with the permission of the author (Panda et al., 2018).
