Differentiation of the shoot is controlled by the ratio of different plant hormones that are present in the plant. The main plant hormones that control shoot differentiation are auxins, cytokinins, and gibberellins.
Explanation:
Auxins and cytokinins are two hormones that play a key role in controlling the differentiation of the shoot. Auxins are responsible for cell elongation and differentiation, and cytokinins are responsible for cell division and differentiation.
Gibberellins are another hormone that plays a role in shoot differentiation. Gibberellins are responsible for stem elongation and cell division, which are important processes in the differentiation of the shoot.
The ratio of these hormones is important in controlling shoot differentiation. The correct ratio of auxins and cytokinins is essential for the differentiation of the shoot. A high cytokinin-auxin ratio is required for shoot differentiation.
When the ratio of cytokinins to auxins is high, it promotes cell division and differentiation, which leads to the formation of the shoot. This is because cytokinins promote the formation of new cells, and auxins promote the differentiation of those cells into specific cell types.
On the other hand, a high gibberellin-cytokinin ratio is not desirable for shoot differentiation, as it promotes stem elongation rather than cell division and differentiation.
Conclusion:
Therefore, the correct ratio of cytokinins and auxins is required for shoot differentiation, and a high cytokinin-auxin ratio is essential for this process.

Ratio of cytokinins to auxins controls differentiation. If both of these are present in equal quantities, the cells divide but fail to differentiate. If there is more cytokinin than auxin, shoot buds develop. If there is more auxin than cytokinin, roots develop...
