Plants with strong apical dominance are typically weakly branched and show

a strong branching response to decapitation

Direct application of cytokinin to axillary buds stimulates

their growth but strigolactone suppresses axillary bud growth. Besides activating BRC1, strigolactone also inhibits cytokinin biosynthesis by negatively regulating the IPT genes.

Apical dominance is regulated by sugar availability. After decapitation, sugars, rapidly accumulate in axillary buds, stimulating bud outgrowth.
