In vitro plant regeneration of Vismia guianensis through organogenesis

A protocol for in vitro plant regeneration through organogenesis was established for Vismia guianensis(Hypericaceae), a species that produces an anti-cancer compound. The highest mean number of shoots per gram of callus (57.33) was obtained on Murashige and Skoog medium supplemented with 4.44 μM 6-benzyl-aminopurine, 5.70 μM indole-3-acetic acid and 12.88 μM gibberellic acid. Rooting was favoured by the addition of 10 μM indole-3-butyric acid, and by sucrose concentrations higher than 1%. This revised version was published online in June 2006 with corrections to the Cover Date.
