Question

Hormone that promotes growth of lateral buds/has negative effect on apical dominance is

• A. Cytokinin
• B. Gibberellin
• C. Auxin
• D. Both B and C

Answer 1

The correct option is A Cytokinin

Apical dominance is a phenomenon in which central stem is dominant and lateral stems are suppressed. It is due to plant hormones auxin produced in the tip of the shoot. It promotes apical dominance and does not allow lateral / axillar buds to grow. Another plant hormone, cytokinin is responsible for having negative effect on the apical dominance. It promotes the growth of lateral buds.

So, the correct answer is 'Cytokinin'
