47. What is the mechanism underlying the phenomenon by which the terminal/apical bud suppresses the growth of lateral buds? Suggest measures to overcome this phenomenon.


The phenomenon by which apical bud suppress the growth of lateral buds is known as apical dominance. It is caused due to release of plant hormone auxin from apical buds.
It can be overcome either by the spray of cytokinin, that promotes the growth of lateral buds or by trimming of bushes which rernove apical buds and allow lateral buds to grow.
