decapitation of plants leads to the activation of axillary buds due to

1. increase in cytokinins
2. more light availability
3. auxin transcolation
4. all of these

Decapitation of plants leads to the activation of axillary buds due to increase in cytokinin. Cytokinins(CK) are a class ofplant growth substancesthat promotecell division, orcytokinesis, in plant roots and shoots. They are involved primarily incellgrowth anddifferentiation, but also affectapical dominance,axillary budgrowth, and leafsenescence.Folke Skoogdiscovered their effects usingcoconut milkin the 1940s at theUniversity of Wisconsin–Madison.
