Effect of sucrose and abscisic acid (ABA) alone or in combination on endogenous phytohormone contents in leaves, sheath-stems, and grains of rice. a and b ABA contents at 5 and 15 days after flowering (DAF), respectively; c and d, indole acetic acid (IAA) contents at 5 and 15 DAF, respectively; e and f, gibberellic acids (GAs) contents at 5 and 15 DAF, respectively; g and h, zeatin ribosides (ZRs) contents at 5 and 15 DAF, respectively. Vertical bars denote standard deviations (n = 3). Different letters indicate significant differences between chemical treatments (P < 0.05)
