Rooting and acclimatization of micropropagatedHypericum perforatumL. native to Sicily

Hypericum perforatum L. is traditionally used as a medicinal plant because of its different bioactive compounds with documented antidepressant and antiinflammatory activities. Plantlets’ mass production with high content of these secondary metabolites has been enhanced through in vitro culture but the process has often been stopped at the multiplication phase. A study was conducted in order to set up an efficient in vitro rooting and acclimatization protocol of a H. perforatum Sicilian genotype well-adapted to south Mediterranean conditions. Aseptic nodal segments were cultured onto a Murashige and Skoog (MS) basal medium supplemented with 4.44 µM 6-benzyladenine for multiplication. Microsh…
