Meta-topolin [6-(3-hydroxybenzylamino)purine] is an aromatic cytokinin. It was first isolated from poplar leaves. Its name is derived from “topolÂâ€?; the Czech word for poplar. The metabolism of meta-topolin is similar to that of other cytokinins. Just as zeatin and BAP; meta-topolin may undergo ribosylation at position 9 without a significant effect on the activity. In Spathiphyllum floribundum; shoot production in media with BAP and meta-topolin is very similar. However; after transfer to the soil; the shoots produced with meta-topolin root much better during acclimatization.S.P.O. Werbrouck; M. Strnad; H.A Van Onckelen and P.C.
