The word 'cytokinin' is a class of plant hormone that promotes cell division in plant roots and shoots. Folke Karl Skoog (July 15 1908-February 15, 2001) discovered their effects using coconut milk in 1940s at the University of Wisconsin-Madison. The adenine type 'cytokinin' is represented by Kinetin, Zeatin and 6-Benzylaminopurine. Most adenine-types are synthesized in roots.The 'cytokinin' acts in concert with auxim, another plant growth hormone. The two are complementary, having generally opposite effects. More 'cytokinin' induces growth of shoot buds, while more auxin induces root formation.

The '6-Bezylaminopurine' (BAP) is a first-generation synthetic 'cytokinin' that elicits plant growth and development responses, setting blossoms and stimulating fruit richness by stimulating cell division. It was first synthesized and tested in the laboratories of plant physiologist Folke K Skoog.

The influence of 'cytokinin' as BAP in combination with other methods on postharvest green color retention on 'broccoli heads' and 'asparagus spears', showed positive results for quality retension. The treatment with 10 and 15 ppm (parts per million) BAP can be used to extend shelf life of fresh-cut broccoli florets and shredded cabbage during storage at 6+-1 deg C at commercial level.
