Question

Mowing of a grass lawn facilitate better maintenance primarily owing to

• A. Removal of apical dominance and promotion of lateral meristem
• B. Wounding which stimulate rapid regeneration
• C. Removal of apical dominance and promotion of intercalary meristems
• D. Removal of apical dominance

Answer 1

The correct option is C Removal of apical dominance and promotion of intercalary meristems

Apical dominance observed in presence of auxin. This results in the growth of the central stem which is dominant and suppresses the growth of the lateral buds. The pruning of the tips or mowing of the grass is done where the tips are cut periodically. There is the removal of the apical dominance and the intercalary meristematic tissues grow. This allows the growth of the other branches.

Thus, the correct answer is option C.
