- Speed up chloroplast maturation
- Cytokinins auxin ratio for rooting and shooting in tissue culture
- 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
