Which of the following is incorrect about vernalisation?

Options

A. It prevents precocious reproductive development
B. It is observed in winter variety of wheat
C. Flowering is stimulated by low temperature
D. It is the resting stage of seeds

Answer

**Step-by-Step Solution:**

1. **Understanding Vernalization**: Vernalization is a process in plants where they are exposed to low temperatures for a certain period. This exposure is essential for the plants to transition from a vegetative state to a flowering state.

2. **Purpose of Vernalization**: The primary purpose of vernalization is to induce flowering in plants, especially in species that require a cold period to flower. This process helps ensure that flowering occurs at the right time, enhancing seed production.

3. **Effects of Vernalization**: Vernalization prevents precocious reproductive development, which means it stops the plant from flowering too early. This delay allows the plant to mature properly before it begins to flower.

4. **Examples of Vernalization**: One common example of vernalization is seen in winter wheat. This type of wheat requires a cold period to trigger flowering.

5. **Analyzing the Options**:
- **Option 1**: "It prevents precocious reproductive development." - This statement is correct.
- **Option 2**: "It is absorbed in winter variety of wheat." - This statement is also correct.
- **Option 3**: "The flowering is stimulated by low temperature." - This statement is correct as well.
- **Option 4**: "It is the resting stage of seeds." - This statement is incorrect. Vernalization is not a resting stage of seeds; rather, it is a process that prepares plants for flowering.

6. **Conclusion**: The incorrect statement about vernalization is option 4, which claims that it is the resting stage of seeds.

**Final Answer**: Option 4 is incorrect about vernalization.
