Question

In callus culture, shoots can be induced by the supply of

• A. Auxin and no cytokinin
• B. Higher concentration of auxin and lower concentration of cytokinin
• C. Higher concentration of cytokinin and lower concentration of auxin
• D. Both auxin and cytokinin in equal amounts

Answer 1

The correct option is C Higher concentration of cytokinin and lower concentration of auxin

Cytokinins are the plant growth hormones that promote cell division in shoot apical meristem while auxins promote the formation of lateral and adventitious roots. So, shoots can be induced by the supply of higher concentration of cytokinin and lower concentration of auxin.

So, the correct option is C.
