Question
Which one of the following symptoms is not due to manganese toxicity in plants?
Answer: Option D
:
D
Manganese competes with iron and magnesium for uptake. With more magnesium available for binding with enzymes, it may induce a deficiency of iron and magnesium.
The iron deficiency causes the appearance of brown spots on the leaves surrounded by chlorotic veins.
Manganese toxicity also inhibits calcium translocation in the shoot apex, which causes calcium deficiency in plants.
