Gibberellic acid (GA) brought about an increase in the rate of dry-weight incorporation into expanding internodea of intact dwarf pea seedlings. The amount of water present in expanding internodes was closely correlated with internode dry weight, and the slope of the relation was unaffected by GA treatment. It is proposed that the effect of GA upon internode expansion is mediated through the change in dry weight. Part of the increase in dry weight brought about by GA was attributable to an increase in the weight of cell wall material. The amount of water present in expanding internodes was found to be correlated with the amount of wall material present. It is possible that the increased rate of wall synthesis which follows GA treatment allows an increase in the rate of cell expansion.
