Biology Question on Plant Growth and Development

How does pruning help in making the hedge dense ?

A

It induces the differentiation of new shoots from the rootstock

B

It frees axillary buds from apical dominance

C

The apical shoot grows faster after pruning

D

It releases wound hormones

Answer

It frees axillary buds from apical dominance

Explanation

Solution

When you prune a hedge, especially by cutting the main or apical shoot, it removes the dominant growth point and allows the dormant axillary buds along the branches to start growing. These axillary buds give rise to new shoots and branches, creating a denser and bushier hedge over time. This process is often referred to as "breaking apical dominance" and is a common technique used in hedge maintenance and shaping.

So, the correct option is (B): It frees axillary buds from apical dominance
