Interveinal chlorosis is due to the deficiency of

Options

A. Fe
B. Mn
C. N
D. B

Answer

**Step-by-Step Solution:**

1. **Understanding Interveinal Chlorosis**: Interveinal chlorosis is a condition where the areas between the veins of leaves turn yellow while the veins themselves remain green. This symptom often indicates a deficiency of certain nutrients in plants.

2. **Identifying Nutrient Deficiencies**: The question provides four options: iron, manganese, nitrogen, and boron. We need to determine which of these deficiencies is specifically associated with interveinal chlorosis.

3. **Analyzing Each Option**:
- **Iron**: Iron deficiency is well-known to cause interveinal chlorosis. This is because iron is essential for chlorophyll synthesis, and its deficiency leads to yellowing of leaf tissue between the veins.
- **Manganese**: Manganese deficiency can also cause chlorosis, but it typically presents differently and is not primarily characterized by interveinal chlorosis.
- **Nitrogen**: Nitrogen deficiency generally causes overall yellowing of the plant, starting with older leaves, rather than interveinal chlorosis.
- **Boron**: Boron deficiency affects cell expansion and can lead to other symptoms, but it does not specifically cause interveinal chlorosis.

4. **Conclusion**: Based on the analysis, the primary nutrient deficiency that leads to interveinal chlorosis is iron. Therefore, the correct answer to the question is **iron**.

**Final Answer**: Interveinal chlorosis is due to the deficiency of **iron**.
