Cytokines are also called plant hormones as they promote cell division which is known as cytokinesis. One of the important cytokinin is Benzylaminopurine, which stimulate several plant development advantages like cell division, basal shoot formation, more side branches, bigger fruits and flowers. 6- Benzylaminopurine is known for inhibiting senescence or for slowing down the process of ageing. The most common cytokinin is Zeatin (Z), which is firstly separated from maize (zea maize). There are various other materials with cytokinin action like benzyl adenine or BA.
For delaying senescence in plants i.e. their ageing and death an application of Benzylaminopurine 40-100 PPM is found to be most effective. It concluded that the death of plant tissue was diminished to half. The accurate mechanism due to which it happens is still not clear but most probably it involves capacity of cytokinins of mobilizing nutrients.
Dose: Recommended dose if 10-40 ppm. Concentration of 2% is prescribed in 1 lt of water.
