Question

Sprouting of potato during storage can be prevented by ______.

Options

• IAA

• Cytokinins

• Gibberellins

• Maleic hydrazide

Answer 1

Sprouting of potato during storage can be prevented by Maleic hydrazide.

Explanation:

Maleic hydrazide is a synthetic growth retardant and sprout inhibitor widely used in agriculture. When applied to potato crops, it translocates into the developing tubers, where it works by blocking and suppressing cell division in the buds or eyes. This effectively prevents sprouting and extends their shelf life during long-term storage, whereas options like IAA, gibberellins, and cytokinins naturally promote growth, cell division, or elongation, which would encourage sprouting instead.
