Name hormone associated with growth inhibiting activities like dormancy and abscission.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a hormone that is associated with growth-inhibiting activities, specifically dormancy and abscission in plants.

2. **Defining Key Terms**:
- **Dormancy**: This refers to a state in which a plant is inactive or not growing, often as a response to unfavorable environmental conditions.
- **Abscission**: This is the process of shedding leaves, fruits, or flowers from a plant, which can occur due to various factors including aging or environmental stress.

3. **Identifying Relevant Hormones**:
- **Abscisic Acid (ABA)**: This hormone is primarily responsible for promoting dormancy in plants, especially during stress conditions such as drought or extreme temperatures. It helps the plant conserve resources and survive unfavorable conditions.
- **Ethylene**: This hormone is involved in the process of abscission, facilitating the shedding of leaves and fruits. It works in conjunction with auxins, which help maintain leaf attachment until they are no longer needed.

4. **Concluding the Answer**: The hormone associated with growth-inhibiting activities like dormancy and abscission is **Abscisic Acid (ABA)**.

### Final Answer:
**Abscisic Acid (ABA)**
