How does pruning help in making the hedge dense

Options

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

B

Explanation

Pruning helps in making the hedge dense as it frees the axillary buds from apical dominance. In fact, the apices of the plant axis (e.g. shoot apex) have the highest concentration of auxin, which suppress the axillary buds while promoting the growth of apical bud. When the shoot apex is cut down through pruning, the axillary buds grow and the hedge becomes dense.
