Question

Pruning makes the hedge plant dense because ...............

• A. Injury induces dense growth.
• B. Apical dominance is removed.
• C. Root sprouts additional branches.
• D. Pruning removes shade and allows germination of new seedlings to impart a dense growth.

Answer 1

The correct option is B Apical dominance is removed.

Auxin present at the shoot tips induces apical dominance. It causes the growth of the tree upwards. When it is pruned, the apical dominance is overcome, so that the axillary growth of the plant is initiated making the hedge plants dense.

So, the correct answer is 'Apical dominance is removed.'
