The harmone widely used in tea plantations for hedge making

Options

A. ABA
B. Auxins
C. `GA_(3)`
D. Ethylene

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the hormone that is widely used in tea plantations specifically for hedge making.

2. **Identifying the Options**: The options provided are:
- A) Auxins
- B) GA3 (Gibberellic Acid)
- C) Ethylene

3. **Analyzing the Role of Auxins**: Auxins are plant hormones that are primarily found at the tips of stems and play a crucial role in plant growth. They are responsible for:
- Promoting apical dominance, which is the phenomenon where the main central stem of the plant grows more vigorously than the side stems.
- Inhibiting the growth of lateral buds, which helps in maintaining a single dominant stem.

4. **Application in Hedge Making**: In tea plantations, auxins are used to encourage bushy growth. When the tips of the plants are trimmed, the auxin concentration decreases, allowing the lateral buds to grow more freely, resulting in a bushier plant. This is why gardeners use auxins to manage the growth of tea plants for hedge making.

5. **Conclusion**: Based on the analysis, the hormone widely used in tea plantations for hedge making is **Auxin**.

**Final Answer**: Auxin
