Question: The deficiency of which one of the following causes lime-induced chlorosis?
Options:
Iron
Zinc
Boron
Magnesium
✅Explanation:
-Lime-induced chlorosis is a common nutritional disorder in plants, especially in calcareous or high-pH soils. In such soils, the availability of iron to plants is reduced, leading to iron deficiency.
-Iron is a crucial component of chlorophyll, the pigment responsible for the green color of plants. When iron is deficient, chlorophyll synthesis is impaired, resulting in chlorosis, which is the yellowing of leaves.

🛑Other Options Explanations:
-(b) Zinc: Zinc deficiency can also cause chlorosis, but it typically appears as interveinal chlorosis (yellowing between the veins).
-(c) Boron: Boron deficiency can lead to various symptoms in plants, including stunted growth, deformed leaves, and fruit cracking.
-(d) Magnesium: Magnesium is a central component of chlorophyll, and its deficiency causes chlorosis, particularly in older leaves.
