Question

Choose the correct answer from the alternatives given.
Apical dominance in plants is due to which of the following plant hormones:

• A. ethylene
• B. gibberellins
• C. auxins
• D. cytokinins

Answer 1

The correct option is C auxins

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. This is due to auxin.

So, the correct option is 'auxins'.
