Summary Mechanically isolated cells from hypocotyl-derived calli of Sideritis angustifolia Lag. were inoculated on agar-solidified Murashige and Skoog (MS) nutrient medium containing CH and different concentrations and combinations of NAA and BA. Isolated cells underwent continued divisions giving rise to calli after 30 days of culture. Best results were obtained when medium was supplemented with 0.5 μM NAA and 4.4 or 8.8 μM BA or with 5 μM NAA and 4.4μM BA. Calli obtained in the presence of 0.5 μM NAA and 8.8 μM BA regenerated shoot-buds when transferred to MS medium without CH and supplemented or not with these growth regulators. Once shoots were excised, the calli maintained their morphogenic competence along several subcultures in hormone-free MS medium. Regenerated shoots were easily rooted on MS medium without growth regulators.
