The vegetative propagation where a branch is injured defoliated and pegged down in the ground in know as

Options

A. layering
B. grafting
C. cutting
D. bud grafting

Answer

**Step-by-Step Solution:**

1. **Understanding Vegetative Propagation:**
- Vegetative propagation is a method of asexual reproduction in plants where new individuals are produced from the vegetative parts of the plant, such as stems, roots, or leaves.

2. **Identifying the Methods of Vegetative Propagation:**
- There are several methods of vegetative propagation, including cutting, grafting, and layering. Each method has its specific process and application.

3. **Analyzing the Given Scenario:**
- The question describes a situation where a branch is injured, defoliated (leaves are removed), and pegged down into the ground. This indicates a method where part of the plant is manipulated to encourage root growth.

4. **Defining Layering:**
- Layering is a specific method of vegetative propagation where a branch is bent to the ground, injured, and covered with soil to encourage root formation while still attached to the parent plant. This method allows the new plant to develop roots while still receiving nutrients from the parent.

5. **Eliminating Other Options:**
- **Cutting:** Involves severing a part of the plant and planting it separately.
- **Grafting:** Involves joining two different plants together to grow as one.
- Since the scenario involves pegging down a branch, it aligns with layering rather than cutting or grafting.

6. **Conclusion:**
- Therefore, the correct answer to the question is **layering**.

**Final Answer:**
The vegetative propagation where a branch is injured, defoliated, and pegged down in the ground is known as **layering**.
