Callus Induction and Synthetic Seed Development in Draceana sanderiana Sanderex Mast: Lucky Bamboo

Abstract

The study was carried out for callus induction and synthetic seed development from the shoot tips of Draceana sanderiana sander ex Mast. The shoot tips were subjected to different concentrations (0.25, 0.5 &1.0 mg/l) of 2,4-D on MS medium. The research findings revealed that the 2,4-D at concentrations of 0.25 mg/l was more suited for the profuse callus formation. The friable and light yellow callus was induced within 2 weeks of culture at 0.25 mg/l of 2,4-D on MS medium as compared to the other two concentrations of 2,4-D i.e.; 0.5 and 1.0 mg/l. Similarly the effect of sodium alginate and calcium chloride percentage on synthetic seed formation was observed, it was found that somatic embryos formed from shoot tips via callus kept in 2.5% sodium alginate and 100 milli molar CaCl2 produced synthetic seeds with firm spherical beads. The study leads to the formation of synthetic seeds of Draceana sanderiana which can be used for the conservation of germplasm through cryopreservation and the micro propagation of the said plant species.
