Data are expressed as means ± standard error, n = 3. For each column, asterisks indicate significant difference between rice cultivars. AP1, AP2 and AM correspond to short branch chains of amylopectin, long branch chains of amylopectin and amylose, respectively. The AP1/AP2 ratio is determined according to the area ratio of AP1 and AP2 fractions
