Select the phytohormone which induces the flowering in mango.

Options

A. ABA
B. Ethylene
C. Cytokinin
D. Auxin

Answer

To solve the question of which phytohormone induces flowering in mango, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify the specific phytohormone that is responsible for inducing flowering in mango trees.

2. **Review the Options**: The options provided are:
- Option 1: ABA (Abscisic Acid)
- Option 2: Ethylene
- Option 3: Cytokinin
- Option 4: Auxin

3. **Recall the Functions of Each Hormone**:
- **ABA (Abscisic Acid)**: Primarily involved in stress responses and seed dormancy.
- **Ethylene**: Known for its role in fruit ripening and also in inducing flowering in certain plants.
- **Cytokinin**: Promotes cell division and can influence shoot formation.
- **Auxin**: Involved in cell elongation and apical dominance but not directly in flowering.

4. **Identify the Correct Hormone**: Based on the functions, ethylene is recognized as a key hormone that induces flowering in various plants, including mango.

5. **Additional Information**: It is noted that ethylene can be applied in the form of a spray (Etyphon) to induce flowering in mango trees, particularly in varieties like Langra and Dasheri.

6. **Conclusion**: The phytohormone that induces flowering in mango is **Ethylene**.

### Final Answer:
The phytohormone which induces flowering in mango is **Ethylene**.
