Auxin and cytokinin is important plant hormone. auxin are class of plant growth hormone cause of cell division and elongation. The synthesis of auxin was found is shoot apical meristem and root apical meristem. In addition cytokinin are class of plant hormone like auxin but cytokinin control cell division growth of the side and affect to the beat apical dominance but promote axillary bud growth. Both auxin and cytokinin is important roles in many aspects of plant growth and development.Another,The interaction between auxin and cytokinin is particularly important to control a few developmental processes
