Question
Differentiation of shoot is controlled by
Options
A. high gibberellin - cytokinin ratio
B.high auxin - cytokinin ratio
C.high cytokinin - auxin ratio
D.high gibberellin - auxin ratio
Solution
Ratio of cytokinins to auxins controls differentiation. If both of these are present in equal quanti ties, the cells divide but fail to differentiation. If there is more cytokinin than auxin, shoot buds develop. If there is more auxin, then cytokinin, root develop.
