Callus from scale segments of Lilium longiflorum 'Gelia' was effectively induced and maintained from unorganized tissue on the semi-solid medium by 0.42% Bacto agar with MS basal salts and vitamins of SH medium supplemented with 0.5 mg/L 2, 4-D, 1.0 mg/L NAA, 0.3 mg/L BA, and 3% sucrose.

Callus from scale segments of Lilium longiflorum 'Gelia' was effectively induced and maintained from unorganized tissue on the semi-solid medium by 0.42% Bacto agar with MS basal salts and vitamins of SH medium supplemented with 0.5 mg/L 2, 4-D, 1.0 mg/L NAA, 0.3 mg/L BA, and 3% sucrose. More than 5% of high sucrose level had inhibiting effect on regeneration capacity of formed callus and decreased callus growth. Various combinations of nitrogen did not effective to proliferate the ELC (Embryogenic-like callus), but friability of callus was increased in the medium containing only nitrate as nitrogen source. 5 mL conditioned medium into 30 mL fresh medium was good for cell growth. However friable cell aggregates during suspension culture had to form hard callus which hindered to establish suspention culture system. Addition of 2 g/L casein hydrolysate increased callus growth and friability of the hard callus. As a result of anatomical observation of callus, organogenesis such as shoots, roots and bulblets was independently induced from callus tissue. Somatic embryogenesis from callus tissue could be observed with low frequency.
