The cultivated strawberry (Fragaria x ananassa Duch.) is a very popular fruit, widely crop in all temperate regions of the world, which have a great economic and nutritive interest due to the high production potential and fruit quality. Considering that, the traditional propagation of the commercial strawberry plant is not always adequate due to the vulnerability and their susceptibility to pathological agents, in vitro micropropagation is the modern method to eliminate this inconvenience. The strawberry cultivar 'Magic' was micropropagated using shoot tip explants for three in vitro subcultures. In vitro rooting of shoots was performed after each subculture on the Murashige & Skoog (MS) basic medium supplemented with IBA (0.5 - 1.0 mg/L-1), and GA3 (0.1 mg/L-1). The highest rooting percentage (88,88 %) of cv. 'Magic' was obtained after the second multiplication subculture at concentration of 0.5 mg/L-1 IBA. Shoots cultivated on the MS medium with 1.0 mg/L-1 IBA produced the higher number of roots (10 units) and the longest roots (2.55 cm). From the observation of the results it can be concluded that the acclimatization may be realized with success using the perlite substrate. 100% of the plants survived in this substrate. The present study was designed to investigate the influence of number of subcultures on multiplication stage and IBA concentration on in vitro rooting of strawberry cultivar 'Magic'.
