Plant regeneration from callus culture of Curcuma aromatica and in vitro detection of somaclonal variation through cytophotometric analysis
Year: 2008
Type: article
Abstract: Callus cultures initiated from shoot base explants of Curcuma aromatica Salisb. were maintained on Murashige and Skoog (MS) media supplemented with 2 mg dm-3 2,4-dichlorophenoxyacetic acid alone or with 0.5 mg dm-3 kinetin. Plantlets were regenerated from 60 and 180-d-old callus on MS media supplemented with 3 mg dm-3 benzyladenine and 0.5 mg dm-3 α-naphthalene acetic acid. Approximately 8-10 plantlets were produced after 30-40 d of culture per 50 mg of callus inoculated. Out of 113 regenerants analyzed 85 plants were exclusively diploid and 28 were predominantly diploid revealing presence of polyploid nuclei. Frequency of polyploid cells were more in regenerants obtained from 180-d-old callus then from 6-d-old callus which might be attributed to the ageing of callus.
