What is Meta-Topolin?

The Uses of Meta-Topolin

Meta-Topolin (m-Topolin) is a highly active aromatic cytokinin.

Biological Activity

Meta-topolin [6-(3-hydroxybenzylamino)purine] is an aromatic cytokinin. It was first isolated from poplar leaves. Its name is derived from “topol”, 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.
