Vascular Cambium is essential for :-

Options

A. Parthenocarpy
B. Grafting
C. Cutting
D. Layering

Answer

**Step-by-Step Solution:**

1. **Understanding Vascular Cambium**: Vascular cambium is a type of lateral meristem found in plants. It is responsible for secondary growth, which increases the thickness (diameter) of stems and roots.

2. **Role in Grafting**: Grafting is a horticultural technique where tissues from one plant are inserted into those of another so that the two sets of vascular tissues may join together. The vascular cambium plays a crucial role in this process.

3. **Process of Grafting**: In grafting, two plant parts are involved:
- **Scion**: The part of the plant that is grafted onto another plant. It is usually a stem or a bud from a desirable variety.
- **Stock (or Stalk)**: The rooted plant onto which the scion is grafted.

4. **Union of Scion and Stock**: For successful grafting, the vascular cambium of the scion must align with the vascular cambium of the stock. This alignment allows for the fusion of the two plant parts, enabling them to grow as one.

5. **Importance of Vascular Cambium**: The vascular cambium is essential in grafting because:
- It facilitates the formation of new vascular tissues (xylem and phloem), which are crucial for the transport of water, nutrients, and food.
- It increases the diameter of the stem and roots, providing structural support to the plant.

6. **Conclusion**: Therefore, vascular cambium is essential for the process of grafting as it enables the successful union of the scion and stock, allowing for proper growth and development of the grafted plant.
