Accumulation characteristic of caryopsis amyloplast in two rice cultivars. a numbers of amyloplast per unit area in pericarp cells; (b) relative areas of amyloplast in pericarp cells; (c) numbers of amyloplast per unit area in endosperm cells; (d) relative areas of amyloplast in endosperm cells. Asterisks above the histogram indicate significant difference between rice cultivars at p < 0.05 (t-test)
