Percentage of water leaf in the soil when plant wilts is known as

Options

A. chresard
B. wilting coefficient
C. field capacity
D. holard

Answer

To answer the question regarding the percentage of water in the soil when a plant wilts, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- First, we need to understand the terms related to soil moisture and plant health. The wilting coefficient is a key term in this context.

2. **Defining Wilting Coefficient**:
- The wilting coefficient is defined as the percentage of water content in the soil at which plants can no longer extract sufficient moisture to maintain turgor pressure. This is the point at which plants begin to wilt and cannot recover without additional water.

3. **Conditions for Wilting**:
- The wilting coefficient occurs when the soil moisture is reduced to a level that is insufficient for the plants to sustain their physiological functions. This typically happens in a saturated atmosphere, meaning that the soil has lost most of its available water.

4. **Conclusion**:
- Therefore, the percentage of water in the soil when a plant wilts is known as the **wilting coefficient**.

### Final Answer:
The percentage of water in the soil when a plant wilts is known as the **wilting coefficient**.
