Q. Apical dominance can be overcome by:

NTA AbhyasNTA Abhyas 2020Plant Growth and Development

Solution:

In higher plants, the growing apical bud inhibits the growth of the lateral (axillary) buds, a phenomenon called apical dominance. Removal of shoot tips (decapitation) usually results in the growth of lateral buds. Cytokinins help overcome the apical dominance. They promote nutrient mobilisation which helps in the delay of leaf senescence.
