Cytokinin
- Biosynthesis
- What it does
- Regulates cell division
- Promote shoot growth by increasing cell
proliferation in the shoot apical meristem
- Promotion of shoot formation in tissue culture
- Delay of leaf senescence
- Increase root
development in
arid conditions
- Apical Dominance
- Apical dominance
- 1. If the apical meristem is
removed no auxin is produced
- 2. IPT turned on and CKX turned off,
cytokini is produced
- 3. Cytokinin promotes cell division in the lateral bud
- 4. The branch meristem starts producing auxin
- 5. ITP is shut down and CKX is
elevated, Cytokin decreases
