The plants requiring short photoperiods for floral initiation and long photoperiods for blossoming are known as

Options

A. long day plants
B. short day plants
C. short long day plants
D. long short day plants

Answer

To answer the question about the plants that require short photoperiods for floral initiation and long photoperiods for blossoming, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Photoperiod**:
- Photoperiod refers to the length of day and night, specifically the duration of light exposure that plants receive in a 24-hour cycle.

2. **Identify Plant Categories**:
- There are different categories of plants based on their photoperiod requirements:
- **Long Day Plants**: These plants require longer photoperiods (more than 12 hours of light) for flowering.
- **Short Day Plants**: These plants require shorter photoperiods (less than 12 hours of light) for flowering.
- **Short Long Day Plants**: These plants require shorter photoperiods for initial floral initiation followed by longer photoperiods for blossoming.
- **Long Short Day Plants**: These plants require longer photoperiods followed by shorter photoperiods.

3. **Analyze the Question**:
- The question states that the plants require short photoperiods for floral initiation and long photoperiods for blossoming. This indicates that the plants first need a shorter duration of light to start the flowering process, and then they need a longer duration of light for the flowers to fully bloom.

4. **Determine the Correct Category**:
- Based on the definitions:
- The plants that require short photoperiods for floral initiation and then long photoperiods for blossoming are classified as **Short Long Day Plants** (SLDP).

5. **Conclusion**:
- Therefore, the answer to the question is that the plants requiring short photoperiods for floral initiation and long photoperiods for blossoming are known as **Short Long Day Plants**.
