How does pruning help in making the hedge dense?

1. It frees axillary buds from apical dominance
2. The apical shoot grows faster after pruning
3. It releases wound hormones
4. It induces the differentiation of new shoots from the rootstock

Correct answer: It frees axillary buds from apical dominance

Solution

Pruning removes the apical bud, which produces auxin that maintains apical dominance and inhibits axillary buds. Once this suppression is lifted, side buds grow into branches, making the hedge denser.
