In a great majority of flowering plants, if the apical bud is intact, it suppresses the development of lateral buds. When the apical bud is removed, lateral buds become active. The phenomenon of suppression of lateral buds by apical bud is called apical dominance. It has been found out, that apical dominance is not due to the mere physical presence of the apical bud, but due to the production and transportation of auxins in/from them. It has been reported that during their polar migration auxins promote the production of axillary buds.
