HELP....Angelina observes that her gardener cuts the tips of her ornamental plants at regular intervals of about 10–15 days. When she asks him why he does this, he tells her that this allows the tree to grow faster and bushier. How would you explain this scientifically?
Cutting the tips of the plant increases the secretion of Abscisic acids, which are present in the apical meristems. This stimulates the growth of the axillary and lateral buds, causing the plant to branch out.
Cutting the tips of the plant increases the secretion of Auxins, which are present in the apical meristems. This stimulates the growth of the axillary and lateral buds, causing the plant to branch out.
Cutting the tips of the plant stops the secretion of Auxins, which are present in the apical meristems. This stimulates the growth of the axillary and lateral buds, causing the plant to branch out.
