Popis: The aim of this study was to establish an efficient protocol for the in vitro propagation of the endangered, endemic and decorative species Dianthus pinifolius Sibth. et Sm. The effects of different concentrations of 6-benzylaminopurine (BAP) and naphtalenacetic acid (NAA), and different explant types (single-node cuttings, terminal buds and shoot cuttings) on shoot multiplication were examined on Murashige and Skoog (MS) and half-strength MS media. The best results were obtained for shoot cuttings on the MS medium supplemented with 0.5 mg/L BAP and 0.1 mg/L NAA, achieving a maximum rate of regeneration (100%) and a total of 15.4 newly-developed shoots per explant. The highest rooting rate (96.7%) was obtained on MS medium containing 1 mg/L NAA, while the acclimatization of the microplants obtained to ex vitro conditions was successful (88.9%).
