Abstract: ABA (Abscisic acid) content (ng g-1 FW) and the ratio of ABA to GA (Gibberellin) in strong potential grains or in the grains of the combination with good plumpness were higher than those in weak potential grains or in the grains of the combination with poor plumpness at early filling stage. Spraying

Key words: Rice, Abscisic acid, Gibberellin, Grain filling
