Question

Hormone responsible for growth of the root in micropropagation is

• A. Auxin
• B. Gibberelin
• C. Cytokinin
• D. Abscisic acid

Answer 1

The correct option is A Auxin

Micropropagation is a method of producing many progeny plants from a selected stock plant, that is a plant from where cells are obtained for culture. This could be a genetically modified plant, an exotic variety of plant or a commercially important variety of plant. While the callus formation is induced by cytokinin, the differentiation requires a certain ratio of growth promoters Auxin and cytokinin. Auxin induces root growth in micropropagated shoots.

So, the correct answer is 'Auxin'
