Embryoidogenesis and plant regeneration from leaf tissue of Gloriosa superba.
The induction, maturation and germination of embryoids from leaf tissue of Gloriosa superba L. were developed by exploiting solid and liquid culture. Nodular calli were obtained from SH medium supplemented with 2,4-D and 2iP. In solid culture, the nodular calli when transferred to 2,4-D along with glycerol gave the best response (68.4 %) in embryoid induction after 20 days. After two subcultures at 7-day intervals in a medium with thiamine instead of glycerol, the embryoids matured. When mature embryoids were transferred to BAP and IBA medium, they gave rise to plantlets with single shoots and roots. In liquid culture, the medium supplemented with NAA and L-glutamine with continuous agitation, the embryoidogenic calli produced embryoids (85 %) after 21 days. The mature embryoids began to turn green and produced shoots and elongated "radicles" after 35 days.
