Which of the following is not an artificial methods of vegetative reproduction?

Options

A. Cutting
B. Grafting
C. Layering
D. Bulbils

Answer

To determine which of the following is not an artificial method of vegetative reproduction, we will analyze each option provided: cutting, grafting, layering, and bulbils.

### Step-by-Step Solution:

1. **Understanding Cutting**:
- Cutting involves taking a part of a plant (like a stem, leaf, or root) and placing it in a suitable environment to grow roots and develop into a new plant.
- This method is widely used in horticulture and is considered an artificial method of vegetative reproduction.

2. **Understanding Grafting**:
- Grafting is a technique where tissues from one plant are inserted into those of another so that the two sets of vascular tissues may join together.
- This method is also artificial as it requires human intervention to combine two different plants into one.

3. **Understanding Layering**:
- Layering involves bending a stem to the ground and covering part of it with soil, allowing it to root while still attached to the parent plant.
- This method is also considered artificial because it requires manipulation by humans to encourage root growth.

4. **Understanding Bulbils**:
- Bulbils are small bulbs that can develop in the axils of leaves or at the ends of stems. They are a natural means of vegetative reproduction found in some plants like Agave and Oxalis.
- Unlike the previous methods, bulbils do not require human intervention to form; they occur naturally as part of the plant's life cycle.

### Conclusion:
- Based on the analysis, **bulbils** is the option that is **not an artificial method of vegetative reproduction**.

### Final Answer:
Bulbils
