Quizplus · Accepted Answer

Auxin is the hormone responsible for promoting apical dominance in plants, which is the phenomenon where the main, central stem of the plant grows more vigorously than the other side shoots. This is largely due to the higher concentration of auxin in the apical meristem (tip of the plant) which inhibits the growth of lateral buds.
