Question

In a plant, deficiency symptom called ‘Die-back of shoots’ was observed. This can be rectified by this element:

विकल्प

• Zinc

• Sulphur

• Iron

• Copper

Answer 1

Copper

Explanation:

1. “Die-back of shoots” is a sign of a copper (Cu) deficit in plants.
2. Photosynthesis, lignin synthesis, and enzyme activation all depend on copper, an important micronutrient.
3. Young shoots wilt, chlorose, and necrotise due to a copper deficit, which ultimately results in die-back.
