The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding the Question**: The question asks about the period between spring and summer and which types of plants thrive during this time. 2. **Identifying Plant Types**: The options provided include: - Short long day plants - Long short day plants - Day neutral plants - Amphiphotoperiodic plants 3. **Defining Short Day Plants**: Short day plants require a shorter duration of light to initiate flowering. The period between spring and summer typically has varying light conditions, which can be favorable for these plants. 4. **Understanding Long Day Plants**: Long day plants require longer daylight hours to flower. The transition from spring to summer generally provides longer days, which can also support flowering in these plants. 5. **Analyzing the Conditions**: The spring to summer period has both short and long day conditions, which can support the flowering of both short day and long day plants. 6. **Conclusion**: The correct answer is that the period between spring and summer is favorable for **short long day plants**. An example of such a plant is **Triticum vulgare** (common wheat), which requires about 8 to 10 hours of light for flowering. 7. **Final Answer**: Therefore, the correct option is **short long day plants**. ---
