In vitro rooting and acclimatization of Sicilian Hypericum perforatum

Hypericum perforatum L. is traditionally used as a medicinal plant because of different bioactive compounds with documented antidepressant and anti-inflammatory activities. Plantlets mass production with high content of these secondary metabolites has been enhanced through in vitro culture but often the process has 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 on to a Murashige and Skoog (MS) basal medium supplemented with 4.44 μM 6-benzyladenine (BA) for multiplication. Micro…
