Removal of shoot tips is very useful technique to boost the production of tea leaves. This is because

  • A
    gibberellins prevent bolting and are inactivated
  • B
    auxins prevent leaf drop at early stages
  • Correct answer
    C
    effect of auxins is removed and growth of lateral buds is enhanced
  • D
    gibberellins delay senescence of leaves

Solution

Removal of shoot tips is a very useful technique to boost the production of tea leaves. This is because effect of auxin is removed and growth of lateral bud is enhanced. This phenomenon in most higher plants in which growing apical buds (shoot tips) inhibit growth of lateral buds due to effects of auxin is called apical dominance.

Hence, the correct answer is option: 'C'.
