The condition of viable seed, when seeds do not germinate even in presence of favourable environmental condition is called

Options

A. dormancy
B. bolting
C. viability
D. quiescence

Answer

To answer the question regarding the condition of viable seeds that do not germinate even in the presence of favorable environmental conditions, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a specific term that describes a condition where seeds, despite being viable and having access to favorable conditions (like moisture, temperature, and light), do not germinate.

2. **Identifying Key Terms**:
- **Viable Seed**: A seed that is capable of germination.
- **Favorable Environmental Conditions**: Conditions that are typically necessary for germination, such as adequate moisture, appropriate temperature, and light.

3. **Exploring the Options**: The options provided are:
- Dormancy
- Bolting
- Viability
- Quiescent stage

4. **Analyzing Each Option**:
- **Dormancy**: This refers to a state where seeds are alive but inactive. In this state, normal physical functions are suspended, preventing germination even when conditions are favorable.
- **Bolting**: This term refers to the rapid elongation of the stem in plants, usually in response to environmental cues, and is not related to seed germination.
- **Viability**: This term refers to the ability of a seed to germinate and grow. It does not describe the condition of non-germination despite favorable conditions.
- **Quiescent Stage**: This term refers to a state of rest or inactivity. However, in the context of seeds, the more specific term used is dormancy.

5. **Conclusion**: Based on the analysis, the correct term that describes the condition of viable seeds that do not germinate even in favorable conditions is **Dormancy**.

### Final Answer:
The condition of viable seed, when seeds do not germinate even in the presence of favorable environmental conditions, is called **Dormancy**.
