Effect of sucrose and abscisic acid (ABA) alone or in combination on the activities of adenosine diphosphate glucose pyrophosphorylase (AGPase), starch synthase (SS), and starch branching enzyme (SBE) in grains of rice. a and b AGPase activity at 5 and 15 days after flowering (DAF), respectively; c and d, SS activity at 5 and 15 DAF, respectively; e and f, SBE activity at 5 and 15 DAF, respectively. Vertical bars denote standard deviations (n = 3). Different letters indicate significant differences between chemical treatments (P < 0.05)
