All the following pairs are growth promoting activites except

Options

A. Tropic growth and pattern formation
B. Flowering and fruiting
C. Seed formation and seed germination
D. Dormancy and Abscission

Answer

To solve the question, we need to identify which of the given pairs does not represent growth-promoting activities in plants. Let's analyze each pair step by step.

### Step-by-Step Solution:

1. **Tropic Growth and Pattern Formation**:
- **Tropic Growth** refers to the growth of a plant in response to a stimulus, either towards it (positive tropism) or away from it (negative tropism). This indicates a growth-promoting activity.
- **Pattern Formation** involves the differentiation of plant cells into various types and orientations, which is part of developmental processes. This also signifies growth-promoting activity.
- **Conclusion**: This pair represents growth-promoting activities.

2. **Flowering and Fruiting**:
- **Flowering** is the process of producing flowers, which is crucial for reproduction in plants.
- **Fruiting** refers to the development of fruits from the fertilized flowers, which is essential for seed dispersal and continuation of the species.
- **Conclusion**: This pair also represents growth-promoting activities.

3. **Seed Formation and Seed Germination**:
- **Seed Formation** is the process where ovules develop into seeds, which is a critical part of the plant's reproductive cycle.
- **Seed Germination** is the process where a seed begins to grow into a new plant, which is a clear indication of growth.
- **Conclusion**: This pair represents growth-promoting activities.

4. **Dormancy and Abscission**:
- **Dormancy** is a period where a plant does not grow, often due to unfavorable environmental conditions. This indicates a halt in growth.
- **Abscission** is the process of shedding parts of the plant, such as leaves or fruits, which is a natural detachment and does not promote growth.
- **Conclusion**: This pair does not represent growth-promoting activities.

### Final Answer:
The correct option is **Dormancy and Abscission**, as these processes do not promote growth in plants.
