Gibberellic acid (GA) does not delay maturation of pea internodes; on the con-trary, maturation (i.e. cessation of extension) takes place slightly earlier. Thus the increased length of internodes resulting from GA treatment is due entirely to increased rate of extension. In this experiment, GA treatment of plants accelerated the visible production of the first flower bud by about 4 days: the node bearing the first flower was not altered. The total number of flower buds produced by the end of the experiment was increased as a result of GA treatment, but many of those first formed on plants receiving high doses (I-IOμg.) withered before opening.
