In higher plants the growing apical bud inhibits the growth of the lateral (axillary) buds, this phenomenon is called

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Concept**: In higher plants, there is a specific growth pattern where the main shoot (apical bud) grows more vigorously than the side shoots (lateral or axillary buds). This is a common phenomenon observed in many plant species.

2. **Identifying the Phenomenon**: The phenomenon where the growing apical bud inhibits the growth of lateral buds is known as "apical dominance." This means that the presence of the apical bud suppresses the growth of the lateral buds.

3. **Mechanism Behind Apical Dominance**: The inhibition of lateral bud growth is primarily regulated by hormones, particularly auxins. These hormones are produced in the apical bud and are transported downwards, which helps maintain the dominance of the apical bud over the lateral buds.

4. **Effects of Removal of Apical Bud**: When the apical bud is removed (a process known as decapitation), the inhibition is lifted, and the lateral buds are allowed to grow. This can be beneficial in horticulture and agriculture, as it can lead to a bushier plant.

5. **Applications**: The concept of apical dominance is applied in various agricultural practices, such as in tea plantations and hedge making, where controlling the growth of lateral buds is essential for desired plant shape and productivity.

**Final Answer**: The phenomenon where the growing apical bud inhibits the growth of lateral (axillary) buds is called **apical dominance**.
