NEET Botany Plant Growth and Development Questions Solved

AIIMS - 2016

In the process of apical dominance, lateral buds are unable to grow in the presence of apical bud. This is due to:-
(a) less amount of cytokinins in lateral buds
(b) more amount of cytokinins in lateral buds
(c) less amount of auxin in lateral buds
(d) more amount of auxin in lateral buds

Lateral bud inhibition (apical dominance) is caused by the auxin diffusing basipetally from the apical bud. The lateral buds are more sensitive to higher concentration of auxins. It is known as theory of direct inhibition of auxin.
