Q. Differentiation of shoot is controlled by
NTA AbhyasNTA Abhyas 2020
Solution:
Caulogenesis is the formation of a shoot from the callus, which occurs due to more concentration of BAP, Kinetin or Zeatin for the plant. This can also be initiated if there is less concentration of IAA, NAA or IBA for the shoot.
Rhizogenesis is the formation of roots from the callus, which occurs due to more concentration of IAA, IBA or NAA in the medium. This can also be triggered if the concentration of BAP, Zeatin or Kinetin is kept less in the medium.
It is in general that cytokinins antagonize the effects of auxins.
If the ratio of cytokinins to auxins is the same, the cells may divide but, differentiation is arrested.
If there is more auxin, there is root differentiation.
