Seed germination rate was recorded as and after 2 and 3 months of cold treatment at 4 °C, respectively. Bulblet explants taken from a germination experiment were cultured on Murashige and Skoog (MS) medium supplemented with – mg/L thidiazuron (TDZ). Maximum bulblet regeneration frequency and bulblets per explants were achieved on a medium containing mg/L TDZ. Leaf disc and leaf scale explants isolated from germinated seedlings were also cultured on MS medium containing 2–6 mg/L 2,4-dichlorophenoxyacetic acid (2,4-D) with a constant concentration of mg/L kinetin. Both explants yielded the highest bulblet regeneration on MS medium containing 2 mg/L 2,4-D and mg/L kinetin. A combination of g/L agar and g/L GELRITE resulted in a maximum bulblet diameter with a higher number of roots. The addition of 10 g/L NaCl to the culture medium resulted in the best root and leaf formation and secondary .
