The aim of this study was to determine the possibility of micropropagation of the medicinal plant A. millefolium on half-strength MS medium and ex vitro rooting and acclimatization of the obtained microshoots in hydroculture in order to establish an efficient production method. Two explant types were used: basal and terminal cuttings, and better results were achieved when terminal cuttings were used. The development of shoots in the multiplication phase was successful with a regeneration percentage of 100%. Ex vitro rooting in a modified Hoagland nutrient solution was successful (83%), but the percentage of in vitro rooting on half-strength MS medium without hormones was higher (95%). However, bearing in mind that mass production of A. millefolium is more efficient when the phase of in vitro rooting is excluded, this method could be recommended for commercial propagation of this medicinal plant. It is necessary to conduct additional research in order to optimize the composition, EC and pH value of the hydroponic nutrient solution.

AbstractPluchea lanceolata is an important medicinal plant of Asteraceae family known for its anti-arthritic and anti-inflammatory activity. A protocol was established for micropropagation of P. lanceolata using nodal explants. Nodal explants were inoculated onto Murashige and Skoog (1962) - MS medium supple–mented with 6-benzylaminopurine (BAP), kinetin (Kin), thidiazuron (TDZ) and 2iP (2-isopentenyladenine) at various concentrations (0.0, 0.5, 1.0, 1.5 and 2.0 mg·dm-3). The highest multiplication rate was obtained for nodal explants cultured on MS medium, supplemented with 0.5 mg·dm-3 thidiazuron (TDZ). In vitro raised shoots were successfully rooted on ½ mineral salt concentration of MS medium supplemented with 1.0 mg dm-3 IBA.

Salvia santolinifolia is a medicinal plant and an efficient in vitro conservation system is established. The influence of N6Benzylaminopurine (BAP), N6-(2-isopentyl)-adenine (2iP) and Kinetin at various concentrations were evaluated, single and in mixture with NAA (Naphthalene acetic acid) for the production of auxiliary shoots from nodal explants of S. santolinifolia. BAP at 3.0 mg/L in MS1 media produced maximum (11.66±3.38) number of shoots while elongated (5.37±1.45) shoots were produced in the MS2 medium in subcultures at 2.0 mg/L of 2iP. Least number of shoots were formed when auxin and cytokinin were used in combination. Length of culture, age was an important consideration for the initiation and development of roots. Rooting of shoot was attained with Indol-3-butyric acid (IBA) (3.0 mg/L) from shoots of 4th, 5th and 6th subculture while shoots taken from 1st, 2nd and 3rd subculture failed to form roots.
