If for a short day plant the light period is interrupted by a short dark period but there is a long uninterrupted long night, will it show flowering?

Answer

To determine whether a short day plant will flower under the given conditions, we can break down the problem step by step.

### Step-by-Step Solution:

1. **Understand Short Day Plants**: Short day plants are those that require a longer duration of darkness (night) and a shorter duration of light (day) to initiate flowering. They typically flower when the night length exceeds a critical duration.

2. **Analyze the Given Conditions**: The question states that the light period is interrupted by a short dark period, but there is a long uninterrupted night. This means that while there is a brief interruption of light, the overall duration of darkness remains long.

3. **Impact of Light Interruption**: In the case of short day plants, a brief interruption of light (short dark period) does not negate the long night. The critical factor for flowering is the length of the uninterrupted darkness.

4. **Conclusion**: Since the long uninterrupted night is maintained, and the light period is only briefly interrupted, the conditions still favor flowering in the short day plant. Therefore, the plant will indeed show flowering.

### Final Answer:
Yes, the short day plant will show flowering because it requires a long period of darkness, which is maintained despite the short interruption of light.
