Introduction: Grafting is the process of joining two different plants or plant parts together to grow as one. The success of grafting depends on the compatibility between the stock and the scion, and the presence of certain tissues between them.

The required tissue: The tissue that is required to be present in between the stock and scion during grafting is Phloem. Phloem is a specialized tissue that transports food and nutrients from the leaves to the roots and other parts of the plant. It is responsible for the movement of organic compounds such as sucrose, amino acids, and hormones.

Function of phloem in grafting: During the process of grafting, the phloem tissue of the stock and the scion must be aligned and connected to ensure the proper transport of nutrients between the two plants. This connection allows for the movement of sugars and other nutrients from the leaves of the scion to the roots of the stock, which helps the plant to grow and thrive.

Other tissues: While phloem is the most important tissue in grafting, other tissues such as xylem, meristem, and parenchyma may also be present between the stock and scion. The xylem tissue transports water and minerals from the roots to the leaves, while the meristem tissue is responsible for growth and development. The parenchyma tissue is a simple tissue that makes up most of the soft parts of the plant.

Conclusion: In conclusion, the tissue that is required to be present in between the stock and scion during grafting is phloem. This tissue is responsible for the transport of nutrients and plays a crucial role in the success of grafting. While other tissues may also be present, phloem is the most important tissue to ensure proper growth and development of the grafted plant.
