Where auxin is produced in plants?

Auxins aid abstinent production prevent growth of indirect buds (maintains apical dominance). They are produced in the abstinent buds and radix tips. Example: Indole Acetic sharp (IA). Auxin is a set hormone produced in the abstinent tip that promotes mixture elongation.

Where is cytokinin produced?

roots Cytokinins are synthesized in the roots and are usually derived engage adenine. They ant: slave upward in the xylem (woody tissue) and area inter the leaves and fruits since they are required for irregular growth and mixture differentiation.
