Vedclass · Answer

(C) In plant tissue culture,the differentiation of callus into organs is regulated by the ratio of auxins (like $IAA$) to cytokinins (like kinetin). When the concentration of cytokinin (kinetin) is higher than that of auxin $(IAA)$,it promotes the development of shoots (caulogenesis). Conversely,a higher concentration of auxin relative to cytokinin promotes root development (rhizogenesis). Therefore,increasing the ratio of kinetin to $IAA$ will lead to shoot initiation.

In tissue culture experiments using tobacco callus,it was observed that when the culture medium contains $2 \ ppm$ of $IAA$ and $2 \ ppm$ of kinetin,an undifferentiated mass of callus is produced. If the ratio of kinetin to $IAA$ is increased,what will happen?
