Floral organs of Lilium ‘Manissa' were used as the explants for callus induction and plant regeneration.The results showed that several parts of floral organs,such as filament,style,ovary,petal and anther,had different re-differentiation capabilities,and the callus induction rates of them were descending in the order as before.The filament was the optimum explants for callus induction.The optimum media for callus induction,proliferation,bud re-differentiation and plantlets rooting were MS+0.5 mg/L 6-BA+0.3 mg/L NAA+0.3 mg/L 2,4-D,MS+0.5 mg/L 6-BA+0.5 mg/L NAA,MS+0.6 mg/L 6-BA+0.6 mg/L NAA and MS+0.1 mg/L NAA,respectively.The percentage of callus induction was 69.56%,regeneration frequency was 100% and rooting rate was 100%.Finally,the plantlets were transplanted onto the matrix made from peat,vermiculite,perlite,garden soil and sand in proportion as 2 ∶ 1 ∶ 1 ∶ 1 ∶ 1,and the survival rate was 92%.
