Which is not a method of vegetative propagation
A. Micropropagation
B. Budding
C. Sowing
D. Layering

Options

A. A. Micropropagation
B. B. Budding
C. C. Sowing
D. D. Layering

Answer

To determine which option is not a method of vegetative propagation, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Vegetative Propagation**:
- Vegetative propagation is a type of asexual reproduction where new plants are produced from the vegetative parts of the parent plant, such as stems, roots, or leaves. This method does not involve the formation of gametes and results in offspring that are genetically identical to the parent.

2. **Analyzing Option A: Micropropagation**:
- Micropropagation is an artificial method of vegetative propagation. It involves the rapid multiplication of plants in a controlled environment, producing multiple identical plants. Therefore, this is a method of vegetative propagation.

3. **Analyzing Option B: Budding**:
- Budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism. This bud is genetically identical to the parent plant. Thus, budding is also a method of vegetative propagation.

4. **Analyzing Option C: Sowing**:
- Sowing refers to the process of planting seeds in the soil. Seeds are the result of sexual reproduction, involving the fusion of gametes. The plants that grow from seeds are not genetically identical to the parent plant, as they exhibit genetic variation. Therefore, sowing is not a method of vegetative propagation.

5. **Analyzing Option D: Layering**:
- Layering is a method of vegetative propagation where a part of the plant (usually a stem) is bent to the ground and covered with soil, allowing roots to form while still attached to the parent plant. This results in a new plant that is genetically identical to the parent. Hence, layering is a method of vegetative propagation.

### Conclusion:
Based on the analysis, the option that is not a method of vegetative propagation is **C. Sowing**.
