Pruning of plants promotes branching because the axillary buds get sensitized to
  1. ethylene
  2. gibberellin
  3. cytokinin
  4. indole acetic acid.

Solution

Cytokinins(CK) are a class ofplant growth substancesthat promotecell division, orcytokinesis, in plant roots and shoots. They are involved primarily incellgrowth anddifferentiation, but also affectapical dominance,axillary budgrowth, and leaf sense. Pruning of plants promote branching because the axillary buds get sensitized to cytokinin.
