Select the odd one out w.r.t. adventitious bud?

Options

A. Foliar bud
B. Cauline bud
C. Extra axilary bud
D. Radical bud

Answer

To solve the question of selecting the odd one out with respect to adventitious buds, we need to analyze the given options and their characteristics:

1. **Foliar Bud**:
- These buds are found at the tip or apex of the shoot.
- They are involved in vegetative propagation, meaning they can give rise to new plants.
- Thus, foliar buds are a type of adventitious bud.

2. **Cauline Bud**:
- Cauline buds are also a type of adventitious bud.
- They grow from the stem and can develop from a normal position to another location on the plant.
- Like foliar buds, cauline buds can also lead to the formation of new plants.

3. **Extra Axillary Bud**:
- Extra axillary buds grow from the stem and node.
- However, they produce leaf bases but do not lead to the growth of new plants.
- This characteristic makes them different from typical adventitious buds.

4. **Radical Bud**:
- Radical buds are another type of adventitious bud.
- They can grow from locations other than the nodes of the plant, similar to foliar and cauline buds.
- They are capable of forming new plants.

Now, comparing all four options, we see that:

- Foliar, Cauline, and Radical buds can all lead to the formation of new plants, which is a key characteristic of adventitious buds.
- The Extra Axillary Bud, on the other hand, does not contribute to the growth of new plants, which makes it the odd one out.

**Conclusion**: The odd one out with respect to adventitious buds is the **Extra Axillary Bud**.
