Auxin-gibberellin interaction in apical dominance.
Indoleacetic acid and gibberellic acid were added to decapitated light-grown ;Alaska' pea seedlings as substitutes for the intact apex in the control of apical dominance. Of various concentrations and combinations tried, a combination of 1% indoleacetic acid + 1% gibberellic acid was the most inhibiting to side bud growth. The greatest degree of hormonally induced side bud inhibition was achieved when seedlings were deprived of soil nutrients.
