Ethylene is liberated during

Options

A. Developing seeds
B. Ripening in some furits
C. Developing ovules
D. Germinating seeds

Answer

**Step-by-Step Solution:**

1. **Understanding Ethylene**: Ethylene is a gaseous plant hormone that plays a crucial role in various plant processes, particularly in the ripening of fruits.

2. **Identifying the Context**: The question asks when ethylene is liberated. The options provided include:
- Developing seeds
- Ripening in some fruits
- Developing ovules
- Germinating seeds

3. **Analyzing Each Option**:
- **Developing Seeds**: Ethylene is not primarily involved in the liberation during the development of seeds.
- **Ripening in Some Fruits**: This is a key function of ethylene. It promotes the ripening process and is known to increase the rate of respiration in fruits, which is termed as "respiration climactic."
- **Developing Ovules**: Similar to developing seeds, ethylene does not play a significant role here.
- **Germinating Seeds**: Ethylene is not liberated during the germination of seeds.

4. **Conclusion**: Based on the analysis, ethylene is primarily liberated during the ripening of some fruits. This is the correct answer.

5. **Final Answer**: Ethylene is liberated during the ripening of some fruits.
