Ginger multiplies vegetatively by

Options

A. bud
B. tuber
C. corm
D. rhizome

Answer

**Step-by-Step Solution:**

1. **Understanding Vegetative Propagation**:
- Vegetative propagation is a form of asexual reproduction where new plants grow from parts of the parent plant. This can include stems, roots, or leaves.

2. **Identifying the Options**:
- The question provides several options for how ginger multiplies vegetatively: bud, tuber, corn, and rhizome.

3. **Evaluating Each Option**:
- **Option A: Bud**: Buds develop into flowers and do not contribute to vegetative propagation. Thus, this option is incorrect.
- **Option B: Tuber**: Tubers, like potatoes, are swollen roots that store nutrients. They do not represent the method of vegetative propagation for ginger. Hence, this option is also incorrect.
- **Option C: Corn**: Corn refers to a type of bulbotuber, which is a modified stem. While it serves as a storage organ, it is not the method by which ginger propagates. Therefore, this option is incorrect as well.
- **Option D: Rhizome**: Rhizomes are modified stems that grow horizontally underground. They store food and can produce new shoots and roots from their nodes, allowing for vegetative propagation. This is the correct method by which ginger multiplies.

4. **Conclusion**:
- The correct answer is **Option D: Rhizome**. Ginger multiplies vegetatively through rhizomes.
