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