Fruit ripening is accelerated by

Options

A. Warm surroundings
B. Increased nitrogen supply
C. Reduced water supply
D. Ethylene rich atmosphere.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks what accelerates the process of fruit ripening. This involves knowing the factors that influence the ripening of fruits.

2. **Identifying the Options**: The options provided are:
- Warm surroundings
- Increased nitrogen supply
- Reduced water supply
- Ethylene rich atmosphere

3. **Analyzing Each Option**:
- **Warm Surroundings**: While temperature can influence ripening, it is not the primary factor that accelerates the process.
- **Increased Nitrogen Supply**: Nitrogen is essential for plant growth but does not directly accelerate fruit ripening.
- **Reduced Water Supply**: This can stress the plant and may not promote ripening; in fact, adequate water is often necessary for healthy fruit development.
- **Ethylene Rich Atmosphere**: Ethylene is a plant hormone known as the "ripening hormone." It plays a crucial role in the ripening process by increasing the rate of respiration in fruits.

4. **Conclusion**: Based on the analysis, the option that most directly accelerates fruit ripening is the "ethylene rich atmosphere."

5. **Final Answer**: The correct answer is **ethylene rich atmosphere**.
