Abstract Aim: Plant production from tissue culture is of high importance from genetic engineering point of view, so in this study, optimization of tissue culture conditions for callus production and plant regeneration of Salsola arbuscula were examined. Material and Methods: Seeds were planted MS medium and after two months, roots, stems (internodes) and leaves explants were transferred to the MS medium with different concentration of 2,4-D and Kinetin hormones for production callus. Plant regeneration was also examined on the various media. Results: Results showed that the best medium to induce callus production were medium of MS + 2,4-D (1 mg/L) + Kin(1 mg/L) and the best explants were roots. So, direct shoot regeneration produced in the medium MS + Kin(1 mg/l) and MS + Kin (0.5 mg/L). Conclusion: Despite production of callus on medium containing only 2,4-D, combined two hormones, auxin and cytokinin, increased the rate of callus production. Also direct shoot regeneration has occurred in medium without auxin. So, production rate of callus and plant regeneration are dependent on amount of external plant growth regulators, and also, amount of external plant growth regulators significantly dependent to genotype and amount of internal plant hormones.
