In a callus culture

A increasing level of cytokinin to a callus induces shoot formation and increasing level of auxin promote root formation

B increasing level of auxin to a callus induces shoot formation and increasing level of cytokinin promote root formation

C auxins and cytokinins are not required

D only auxin is required for root and shoot formation

ANS:A - increasing level of cytokinin to a callus induces shoot formation and increasing level of auxin promote root formation

A high ratio of auxin- to -cytokinin or cytokinin-to-auxin induces root and shoot regeneration, respectively (Skoog & Miller, 1957).
