Mowing grass lawn facilitates better maintenance because:

Options

AWounding stimulates regeneration
BRemoval of apical dominance and stimulation of intercalary meristem
CRemoval of apical dominance
DRemoval of apical dominance and promotion of lateral meristem

Correct answer

B. Removal of apical dominance and stimulation of intercalary meristem

Step-by-step solution

Apical dominance is a common observation in vascular plants. If apical meristem is intact & growing, the lateral tips growth is suppressed. According to Thirnann & Skoog the Auxin, synthesized in apical meristem, in translocated downwards & inhibits the growth of lateral tips. That is why mowing -grass lawns facilitates better maintenance.
