In recent years, callus tissue induction has been introduced as a new method for obtaining secondary metabolites. The aim of this study was to inoculate callus from the isolated leaves of Datura seedlings to obtain the best hormonal concentration for maximum callus production. Datura seeds were cultured in MS medium under sterile conditions and Datura seedlings were obtained. The leaves of the seedlings were isolated and transferred to the MS medium without hormone, but the callus did not occur. In the next step, the leaves of the seedlings were transferred to the MS medium in 9 hormonal treatments containing different concentrations of auxin 2,4-D and cytokinin kinetin (Kin). the samples with light period was 16 hours of light and 8 hours of darkness and temperatures of 25 ° C for four week. The results showed that maximum callus formation in MS medium containing two hormones with concentrations of 1 mg/L 2,4-D and 1 mg/L Kin was obtained.
