How will you induce lateral branching in a plant, which normally does not produce them ? Give reason in support of your answer.

Lateral branching in a plant can be induced by removing the apical bud. Auxin causes the phenomenon of apical dominance, i.e. suppression of development of lateral buds into branches in the presence of apical bud. This suppresses the growth of the lateral buds. On removal of the apical buds, Auxin hormone is removed and the inhibition of apical dominance can be overcome to allow the lateral branches to develop.
