Answer

To answer the question "In grafting, scion forms," we will break down the concepts involved in grafting and identify what the scion contributes to the process.

### Step-by-Step Solution:

1. **Understanding Grafting**:
- Grafting is a horticultural technique where a portion of one plant (the scion) is attached to another plant (the rootstock or stalk) to grow together as one plant.

2. **Identifying the Components**:
- In grafting, there are two main components:
- **Scion**: This is the part of the plant that is grafted onto the rootstock. It typically contains the shoot system, which includes stems, leaves, and sometimes flowers.
- **Rootstock**: This is the part of the plant that provides the root system.

3. **Function of the Scion**:
- The scion is responsible for forming the shoot system of the new plant. It contributes the upper part of the plant, which includes the stem and leaves.

4. **Conclusion**:
- Since the question asks what the scion forms in grafting, the correct answer is that the scion forms the **shoot system**.

5. **Final Answer**:
- Therefore, the answer to the question is **Option A: shoot system**.
