What is the phenomenon of the apical dominance in plants? How it can be artificially eliminated?
The Apical dominance is the phenomenon by which high (over the positive range limit) auxin concentrations due to auxins from the apical bud moving downward the stem inhibit the growth of the lateral buds of the plant. At the starting of the stem development the apical dominance causes the plant growth to be longitudinal (upwards) since the growth of the lateral buds remains inhibited. Since the lateral buds become more distant from the apex the auxin concentration in these buds lowers and shoots grow more easily.The growth of tree branches able to stimulated preventing the apical dominance by the removal of the apical bud.
