- Natural- Zeatin and di-phenyl urea
- Dihydrozeatin (DHZ) is a naturally occuring cytokinin
- Sythetic –kinetin
- Coconut milk is rich in cytokinins
Major effects
- Cell division
- Cell elongation
- Speed up chloroplast maturation
- Cytokinins auxin ratio for rooting and shooting in tissue culture

| Auxin:Cytokinin Ratio |
- Overcome apical dominance exerted by auxin
- Delay senescence and increase shelf life
- Helps to mobilize solutes and other nutrients
What are pomalins? A combination of cytokinins and gibberrillin is effective
in increasing apple size
Major site of production: root apical meristem
