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

  1. A
    Gibberellins prevent bolting and are inactivated.
  2. B
    Auxins prevent leaf drop at early stages.
  3. C
    Effect of auxins is removed and the growth of lateral buds is enhanced.
  4. D
    Gibberellins delay the senescence of leaves.

Solution & Step-by-step Explanation

Shoot tips produce Auxins, which promote apical dominance (inhibiting the growth of lateral/axillary buds). By removing the shoot tip (decapitation), the source of auxin is removed, allowing the lateral buds to grow and produce more branches and leaves, which is desirable in tea plantations and hedge making.
