  1. Mowing grass lawn facilitates better maintenance because
    1. wounding stimulates regeneration
    2. removal of apical dominance and stimulation of intercalary meristem
    3. removal of apical dominance
    4. removal of apical dominance and promotion of lateral meristem
Correct Option: B

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