Sorbuses are deciduous trees or shrubs belong to the family Rosaceae, mainly use them as ornamental or medicinal, fruit plant. In this work, in vitro sterile culture of Sorbus aria ‘Gran Sasso’ was established on half-strength Murashige and Skoog (MS, 1962) basal medium, and examined its shoot and root productions. The ideal cytokinin concentration and type for in vitro shoot development (with more than five shoot per plant specimen) were 0.4 and 0.8 mg/l BA or BAR, lower dosages or other cytokinins (especially KIN) was not effective, however, KIN resulted the longest and widest leaves. After a short (48-hour) period of root stimulation on an induction medium containing 15 mg/l IBA auxin, the hormone-free medium containing 0.75 g/l activated charcoal proved to be the best, but even in this case, it was not possible to achieve a rooting rate better than 36.7%. Silver nitrate was not resulted rooting in every doses, although higher concentrations (2 and 5 mg/l) decreased average shoot number and effectively increased shoots’ length and leaf sizes.
