Options

A. Begonia
B. Diosocrea
C. Rose
D. Bryophyllum

Answer

**Step-by-Step Text Solution:**

1. **Understanding Vegetative Propagation**:
- Vegetative propagation is a form of asexual reproduction in plants where new individuals are produced from the vegetative parts of the plant such as leaves, stems, or roots.

2. **Analyzing the Options**:
- We will evaluate each option provided in the question to determine which plant uses bulbils for vegetative propagation.

3. **Option A: Vagonia**:
- Vagonia does not reproduce through bulbils. Instead, it reproduces by producing small plantlets from its leaves, stems, and roots.
- **Conclusion**: This option is incorrect.

4. **Option B: Dioscorea**:
- Dioscorea is known for producing bulbils, which are small bulbs that can develop into new plants. This is a key characteristic of vegetative propagation in this genus.
- **Conclusion**: This option is correct.

5. **Option C: Rose**:
- Roses typically reproduce through stem cuttings, not bulbils. This method involves taking a part of the stem and allowing it to root and grow into a new plant.
- **Conclusion**: This option is incorrect.

6. **Option D: Bryophyllum**:
- Bryophyllum propagates through leaf cuttings where new plantlets can grow from the edges of the leaves when they come into contact with the soil. This does not involve bulbils.
- **Conclusion**: This option is incorrect.

7. **Final Answer**:
- The correct answer to the question "Vegetative propagation by bulbils found in?" is **Dioscorea**.
