Accelerate plant cell division, promote flowering, produce fruit, break plant dormancy, and enhance photosynthesis. Improve disease resistance. Some natural cytokinins are 6 – furfurylaminopurine, ribosylzeatin (immature corn), zeatin, isoamyl adenine and dihydrozeatin. Interestingly, the above-mentioned compounds are also present in the denatured products of nucleic acids.
There are also many synthetic cytokinins on the market, such as 6 – benzylaminopurine and 6 – phenylaminopurine. Cytokinin acts on the cell that produces it-the “autocrine” system. Cytokinins are temporarily inactivated by glycosylation at N 3, N 7 and N 9. Cytokinins can be irreversibly degraded by oxidative lysis. Diphenylurea is one of the synthetic cytokinins. Thiadiazole is a new class of cytokinins, which inhibits cytokinin oxidase, which is why it is widely used in plant tissue culture. There are 200 or more synthetic cytokinins.
