Magnesium and Manganese in Plants

• Magnesium (Mg) and Manganese (Mn) are essential nutrients for the growth and development of plants.

• Magnesium is a component of chlorophyll and is important for photosynthesis. It also plays a role in several metabolic processes.

• Manganese is involved in enzyme activation and is important for photosynthesis, respiration, and nitrogen metabolism.

Statements:

(i) Magnesium competes with iron and manganese for uptake and with iron for binding with enzymes.

• Magnesium competes with iron and manganese for uptake by the plant roots.

• It also competes with iron for binding with enzymes.

• This competition can lead to deficiencies of iron and manganese in the plant.

• Therefore, statement (i) is correct.

(ii) Magnesium inhibits calcium translocation in shoot apex.

• Magnesium does not inhibit calcium translocation in the shoot apex.

• However, calcium and magnesium are both cations and can compete for uptake by the plant roots.

• Therefore, statement (ii) is incorrect.

(iii) Excess of manganese may induce deficiencies of iron, magnesium and calcium.

• Excess of manganese can lead to deficiencies of iron, magnesium, and calcium in the plant.

• This is because manganese can interfere with the uptake and translocation of these nutrients.

• Therefore, statement (iii) is correct.

(iv) Symptoms of manganese toxicity may actually be the deficiency symptoms of iron, magnesium and calcium.

• Symptoms of manganese toxicity can resemble the deficiency symptoms of iron, magnesium, and calcium.

• This is because excess manganese can interfere with the uptake and translocation of these nutrients.

• Therefore, statement (iv) is correct.

Conclusion:

• Statements (i), (iii), and (iv) are correct.

• Statement (ii) is incorrect.
