A method of breaking dormancy and allowing ample absorption of water is

Options

A. Stratification
B. Scarification
C. Vernalization
D. Devernalization

Answer

To solve the question regarding the method of breaking dormancy and allowing ample absorption of water, we will analyze each option provided:

### Step-by-Step Solution:

1. **Understanding Dormancy**:
- Dormancy in seeds refers to a state where the seed is inactive and does not germinate despite favorable conditions. Breaking this dormancy is essential for germination.

2. **Analyzing the Options**:
- **Stratification**: This method involves moistening the hard seed coat and exposing it to oxygen. It is primarily used to break dormancy in seeds that require a period of cold treatment.
- **Scarification**: This method involves breaking or softening the hard seed coat, allowing water to penetrate and initiate the germination process. It is specifically aimed at breaking dormancy in seeds with tough outer coatings.
- **Vernalization**: This process involves exposing seeds to low temperatures to promote flowering, not directly related to breaking seed dormancy.
- **De-vernalization**: This is the reverse of vernalization, where high temperatures are applied to stop the flowering process. It does not relate to seed dormancy.

3. **Identifying the Correct Method**:
- Among the options, **scarification** is the method that specifically breaks dormancy by allowing seeds to absorb water effectively. It is particularly useful for seeds with hard coats that prevent water absorption.

4. **Conclusion**:
- The correct answer to the question is **scarification**.

### Final Answer:
The method of breaking dormancy and allowing ample absorption of water is **scarification**.
