• An insoluble (particulate) 3^H-IAA-binding system similar to that reported by Hertel et al. (3) is described in buds from pea seedlings. The binding is competed by NAA as well as IAA. Auxin-competible binding is optimal at 25℃ and pH 6.5; Ca^<+2> increases binding as does a 1 hr preincubation at 4℃. Release of apical dominance produces outgrowth and a large decrease in the NAA-competible 3^H-IAA-binding activity in the axillary buds; this correlates with a decreased ability of auxin to inhibit the buds. Both the antiauxin triiodobenzoic acid and the cytokinin benzyladenine also compete with the bound IAA.
