- aData represent means ± standard deviations, n = 2. AP1, AP2, and AP1/AP2 represent the relative fractions correspond to short (AP1) and long (AP2) branch chains of amylopectin, and the degree of amylopectin branching (AP1/AP2), respectively. AM represents the true amylose content (AM) as determined by gel permeation chromatography (GPC) parameters. The relative crystallinity was calculated from XRD. Ratios of 1047/1022 represents the amount of ordered starch calculated from ATR-FTIR. The small letters in each column indicate significant differences among genotypes (P < 0.05)
