Effect of sucrose and abscisic acid (ABA) alone or in combination on seed-setting rate, pollen tube growth, grain weight, and grain morphology of rice. a Effect of sucrose and ABA alone or in combination on the seed-setting rate; b, effect of sucrose and ABA alone or in combination on the pollen germination rate; c and d, effect of sucrose and ABA alone or in combination on pollen tube elongation; e, effect of sucrose and ABA alone or combination on kernel weight; f–h, effect of sucrose and ABA alone or in combination on grain size. Vertical bars denote standard deviations (n = 3). Different letters indicate significant differences between chemical treatments (P < 0.05)
