In this paper, the effects of a number of growth regulators as well as supplements to the Murashige and Skoog (MS) basal medium were evaluated on the regeneration of Alstroemeria rhizome explants. In the first experiment the effects of three cytokinins (BA, TDZ and 2IP each at 0.5, 1 and 2 mg/l) in combination with NAA (0.2 mg/l), followed by another PGR combination of 2IP (at 0.5, 1 and 2 mg/l) with NAA (0 and 0.2 mg/l), on regeneration of rhizome-derived explants, was investigated. Through the second experiment, the effects of a number of supplements, including glucose (30 g/l as the alternative for sucrose), casein hydrolysate (1 g/l), asparagine and glutamine, (each at 30 mg/l) added to MS medium, containing 1 mg/l BA and 0.2 mg/l NAA, was examined on rhizome explants’ regeneration. Among the tested cytokinins, BA induced better regeneration of rhizome explants, resulting in a higher number of shoots compared to the other cytokinins. A medium supplemented with 1 mg/l BA and 0.2 mg/l NAA proved to be the most effective, with an average of 4.16 regenerated shoots per explant. In the second PGR combination, addition of NAA at 0.2 mg/l improved regeneration, compared to NAA-free treatments. In the second experiment, glucose substitution for sucrose improved regeneration with an average of 5.10 regenerated shoots per explant, compared to 4.16 shoots in sucrose-containing medium; whereas glutamine and asparagine (with 2.66 shoots) and casein hydrolysate (with 3.80 shoots) showed a negative influence on rhizome explants’ regeneration.
