Vernalization is the effect of low temperature on:

Options

A. Delaying of flowering
B. Inhibition of flowering
C. Acceleration of fruit ripening
D. Acceleration of flowering

Answer

**Step-by-Step Solution:**

1. **Understanding Vernalization**: Vernalization refers to the process in which certain plants require exposure to low temperatures to trigger flowering. This is a crucial developmental process for many plant species.

2. **Identifying the Role of Low Temperature**: In the context of vernalization, low temperatures serve as a signal for the plant to transition from a vegetative state to a flowering state. This means that the plant has a physiological requirement for cold exposure to flower.

3. **Analyzing the Options**: The question provides four options regarding the effect of low temperature due to vernalization:
- Option 1: Delay in flowering
- Option 2: Inhibition of flowering
- Option 3: Acceleration of fruit ripening
- Option 4: Acceleration of flowering

4. **Evaluating Each Option**:
- **Option 1** (Delay in flowering): This is incorrect because vernalization does not delay flowering; rather, it promotes it.
- **Option 2** (Inhibition of flowering): This is also incorrect as vernalization does not inhibit flowering; it facilitates it.
- **Option 3** (Acceleration of fruit ripening): This is not related to vernalization, which specifically pertains to flowering, not fruit ripening.
- **Option 4** (Acceleration of flowering): This is correct because vernalization is indeed the process that accelerates flowering in response to low temperatures.

5. **Conclusion**: Based on the analysis of the options, the correct answer to the question "Vernalization is the effect of low temperature on:" is **acceleration of flowering**.

**Final Answer**: Vernalization is the effect of low temperature on **acceleration of flowering**.
