Question

for callus formation , auxin and cytokinin are involved in which ratio?
(A) balanced
(B) only cytokinin required
(c) low auxin, very high cytokinin
(D) only auxin

Answer 1

Option C is correct....

...The ratio of auxin to cytokinin plays an important role in the effect of cytokinin on plant growth. Cytokinin alone has no effect on parenchyma cells. When cultured with auxin but no cytokinin, they grow large but do not divide. When cytokinin is added, the cells expand and differentiate. When cytokinin and auxin are present in equal levels, the parenchyma cells form an undifferentiated callus. More cytokinin induces growth of shoot buds, while more auxin induces root formation
