Question

The shoot branching depends upon the development of axillary buds, but many of the buds in axillary position never grow out due to the _____________________.

• A. Inhibitory factor present in the axillary bud
• B. Inhibitory factor present in the apical bud
• C. Interaction of factors present in both the axillary & apical bud
• D. Inhibition under genetic control

Answer 1

The correct option is B Inhibitory factor present in the apical bud

An axillary bud is an embryonic or organogenic shoot that lies dormant at the junction of the stem and petiole of a plant. Axillary buds do not become actively growing shoots on plants with strong apical dominance. Apical dominance occurs because the shoot apical budproduces auxin which prevents axillary buds from growing.

So, the correct option is B.
