Which hormone is involved in the regulation of apical dominance? (2019)

Step 1: Understand what apical dominance means. It is the phenomenon where the main central stem of the plant grows more strongly than the side branches.
Step 2: Learn about hormones in plants. Hormones are chemicals that help control growth and development.
Step 3: Identify the hormone involved in apical dominance. The hormone responsible is called auxin.
Step 4: Know the role of auxins. Auxins help the main stem grow taller and inhibit the growth of side branches (lateral buds).
Step 5: Conclude that auxins are crucial for maintaining apical dominance by preventing lateral buds from growing.
