Apical dominance is a common observation in vascular plants. If apical meristem is intact & growing, the lateral tips growth is suppressed. According to Thimann & 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.

Mowing and Grass Lawn Maintenance
Mowing is an essential practice in lawn care that promotes healthy grass growth. The correct answer to why mowing facilitates better maintenance is option 'B': removal of apical dominance and stimulation of the intercalary meristem. Below are the explanations of these concepts:
Apical Dominance
- Definition: Apical dominance refers to the phenomenon where the main, central stem of a plant grows more vigorously than the lateral branches. This is due to the production of growth hormones, primarily auxins, at the tips of the plant.
- Impact of Mowing: When grass is mowed, the top portion of the plant, including the apical dominance, is removed. This encourages the grass to redirect its growth hormones, allowing for more lateral growth and a fuller, denser lawn.
Intercalary Meristem Stimulation
- Definition: Intercalary meristems are regions of actively dividing cells located at the base of leaves and internodes in grasses. These meristems play a crucial role in grass regeneration and growth.
- Role in Mowing: Mowing stimulates these intercalary meristems to activate, leading to quicker recovery and regrowth. This regenerative capacity is particularly important for grasses, which are often subject to mechanical stress.
Benefits of Mowing
- Enhanced Growth: By removing the apical dominance, mowing allows for a more even distribution of growth across the grass, resulting in a thicker and healthier lawn.
- Improved Photosynthesis: Encouraging lateral growth also improves light penetration and photosynthesis, promoting overall plant health.
In summary, mowing not only helps in maintaining the aesthetic appeal of a lawn but also fosters healthy regrowth by removing apical dominance and stimulating intercalary meristem activity. This practice ensures a lush, vibrant lawn.
