(a) Auxins and cytokinins act antagonistically in relation to apical dominance.
(b) The auxins allow dominance of apical bud while cytokinins stimulate the growth of lateral buds.
(c) Application of cytokinins to lateral buds relieves them from apical inhibition.
(d) In the presence of cytokinins, supply of water and
minerals increases to these buds, and therefore, the lateral buds grow even in the presence of apical bud.
