Consider the following statements. Apical dominance in plants I. Allows plant growth II. Retards the growth of lateral buds III. Enhances the growth of lateral buds. Which of these statements is/are correct?

Options

  1. AI alone
  2. BII alone
  3. CIII alone
  4. DI and II

Correct answer

D. I and II

Step-by-step solution

The auxins in apical bud inhibit the development of lateral buds and the phenomenon is called apical dominance, but it allows apical growth. Recent investigations support that auxins induce the formation of ethylene which acts as inhibitor for lateral buds.
