The initiation development of floral primordium takes place by

Options

A. Only by hormonal changes in plant
B. Only structural changes in plant
C. Changes in seasonal variation
D. Both by hormonal and structural changes in plant

Answer

**Step-by-Step Solution:**

1. **Understanding Floral Primordium**:
- Floral primordium refers to the early developmental stage of flowers, which appear as small buds at the end of the stem. These buds are the precursors to future flowers.

2. **Identifying the Process of Development**:
- The question asks about the initiation and development of floral primordium. This process involves changes that lead to the transformation of the bud into a flower.

3. **Factors Influencing Development**:
- The development of floral primordium is influenced by various factors, including hormonal changes, structural changes, and seasonal variations.

4. **Hormonal Changes**:
- Auxin is a key plant hormone that promotes growth. During the development of floral primordium, the level of auxin increases, which plays a crucial role in the growth and differentiation of the bud into a flower.

5. **Structural Changes**:
- As the floral primordium develops, structural changes occur. The bud undergoes morphological changes to form different parts of the flower, such as sepals, petals, and reproductive organs.

6. **Conclusion**:
- The initiation and development of floral primordium occur due to both hormonal changes (increased auxin levels) and structural changes (morphological development). Therefore, the correct answer is that it takes place by both hormonal and structural changes.

**Final Answer**: The initiation and development of floral primordium takes place by both hormonal and structural changes.
