Select correct statement w.r.t. florigen.

Options

A. It is formed in leaves and shoot apeices
B. When exposed to the inductive photoperiod florigen migrates from leaves to shoot apex
C. Initial flowering occurs without migration of florigen to the shoot apex
D. It is not a plant hormone

Answer

To solve the question regarding the correct statement with respect to Florigen, we will analyze each of the provided statements step by step.

### Step 1: Understanding Florigen
Florigen is a plant hormone that plays a crucial role in the flowering process of plants. It is produced in response to certain environmental cues, particularly light.

**Hint:** Remember that Florigen is associated with the flowering process in plants.

### Step 2: Evaluating the Statements
We need to evaluate the four statements given in the question:

1. **"It is formed in leaf and shoot apex."**
- This statement is incorrect. Florigen is primarily formed in the leaves, not in the shoot apex.

**Hint:** Focus on where Florigen is synthesized; it is primarily in the leaves.

2. **"When exposed to the inductive photoperiod, Florigen migrates from leaves to shoot apex."**
- This statement is correct. Florigen is produced in the leaves and migrates to the shoot apex when the plant is exposed to the right photoperiod, triggering flowering.

**Hint:** Consider the role of light in the migration of Florigen.

3. **"Initial flowering occurs without migration of Florigen to shoot apex."**
- This statement is incorrect. Initial flowering is dependent on the migration of Florigen to the shoot apex, which is triggered by the appropriate light conditions.

**Hint:** Think about the necessity of Florigen's movement for flowering to occur.

4. **"It is not a plant hormone."**
- This statement is also incorrect. Florigen is indeed classified as a plant hormone.

**Hint:** Recall the definition of plant hormones and their functions.

### Step 3: Conclusion
After evaluating all the statements, we find that the only correct statement regarding Florigen is the second one: **"When exposed to the inductive photoperiod, Florigen migrates from leaves to shoot apex."**

### Final Answer
The correct statement with respect to Florigen is:
**"When exposed to the inductive photoperiod, Florigen migrates from leaves to shoot apex."**
