Detailed explanation-1: -The apical bud produces a hormone called Auxin which inhibits the growth of the lateral buds. When the apical bud is removed from the plant, the Auxin gets automatically removed and due to which the lateral buds grow very fast and make the plant bushy in nature.
Detailed explanation-2: -By removing the apex, pruning temporarily destroys apical dominance and stimulates the growth of lateral buds into shoots. Figure 4. Pruning stimulates lateral shoot growth close to the cut. Pruning also reduces the size of the above-ground portion of the plant in relation to the root system (Fig.
Detailed explanation-3: -Apical buds form auxin hormones that promote apical dominance and stop the lateral bud growth.-If the apical bud is removed, the auxin source is removed. Due to this, the lateral buds grow faster and make the plant bushy.
