Choose the correct statement regarding the phenomenon described in the diagram.

Options

  1. AIn most higher plants, the growing axillary bud inhibits the growth of the apical bud.
  2. BDecapitation of shoot tips is done to inhibit this phenomenon.
  3. CInhibition of this phenomenon results in growth of apical buds
  4. DThis phenomenon is mostly seen in lower plants.

Correct answer

B. Decapitation of shoot tips is done to inhibit this phenomenon.

Step-by-step solution

In most higher plants, the growing apical bud inhibits the growth of the lateral (axillary) buds, a phenomenon called apical dominance. Removal of shoot tips (decapitation) usually results in the growth of lateral buds. In [A] it's written the growing axillary buds whereas growing apical buds inhibit growth of axillary bud. In[C] inhibition of apical dominance results in growth of lateral buds not apical buds. In [D] This phenomenon is mostly seen in higher plants not lower plants.
