Question

Deficiency of molybdenum leads to

• A. Mottling and necrosis of leaves
• B. Yellowing of leaves
• C. Bending of leaves
• D. All of the above

Answer 1

The correct option is D All of the above

Molybdenum is an essential micronutrient required as activator of certain enzymes, involved in nitrogen metabolism including nitrate reduction and nitrogen fixation, ascorbic acid oxidase etc. Molybdenum deficiency leads to mottling chlorosis with bending or infolding of leaves, whiptail in crucifers, withering in monocots and loosening of cauliflower head. The chlorosis leads to yellowing of leaves.
