Main objective of the research is cultivation and propagation of valuable medicinal plant Aspatagus officinalis L. (Mary Washington) by hydroponics and in vitro combined method. From seeds of hydroponic plants were obtained in vitro plantlets. To obtain callus tissues various explants (hypocotyl, root, apical bud, stem segment) were separated from micro-plantlets. In vitro callus cultures were obtained. Biosynthetic possibility and activity of callus tissues in case of various growth regulators and concentrations were determined. All tested explants on MS nutrient medium with hormones (BAP - 1.0 mg/l, 2.4D - 2.0 mg/l and BAP - 1.0 mg/l, 2.4D - 0.5 mg/l, α-NAA - 0.5 mg/l) inducted callus tissues. The replanting of callus was implemented once in a month, on the fresh nutrient medium. Viable callus cultures were obtained and used for induction of rhizogenesis and organogenesis. On MS medium optimum result was in case of callus from hypocotyl explant, with BAP - 1.0 mg/l, 2.4D - 0.5 mg/l and α-NAA - 0.5 mg/l or Kinetin - 1 mg/l concentration, which provided regeneration of 15 - 20 adventive shoots. Shoot-regenerants multiplicated micro-clonaly. Among tested phytohormones the best result was 0.5 mg/l IBA concentration, providing 62% rhizogenesis of shoot-regenetants. In spring, the rooted in vitro micro-plantlets after acclimatization were planted in the open air gravel hydroponic conditions for propagation.
