Manganese deficiency typically shows what symptom?

• A. New leaf chlorosis
• B. Interveinal chlorosis on young leaves
• C. Soft tissue becoming brittle
• D. Blossom-end rot in fruits

Answer: (B)

Manganese deficiency in plants shows up as chlorosis that begins in the new growth because manganese is relatively immobile in the plant. The classic sign is interveinal chlorosis on young leaves—yellowing occurs between the leaf veins while the veins themselves stay green. This pattern reflects Mn’s role in chlorophyll formation and photosynthetic enzyme function, and the fact that deficiency shows first where growth is active.

Other symptoms listed aren’t typical Mn deficiency signs. General new-leaf chlorosis is less specific, and problems like tissue becoming brittle or blossom-end rot in fruits point to different nutrient issues or conditions (such as calcium transport problems or other mineral imbalances).
