Which one of the following symptoms is not due to manganese toxicity in plants?
1 Calcium translocation in shoot apex is inhibited
2 Deficiency in both Iron and Nitrogen is induced
3 Appearance of brown spot surrounded by chlorotic veins
4 None of the above
Explanation:
The prominent symptom of manganese toxicity is the appearance of brown spots surrounded by chlorotic veins. It is important to know that manganese competes with iron and magnesium for uptake and with magnesium for binding with enzymes. Manganese also inhibit calcium translocation in shoot apex. Therefore, excess of manganese may, in fact, induce deficiencies of iron, magnesium and calcium
