Abstract

Indirect regeneration of plantlets from multiple shoot induction of Corallocarpus epigaeus was obtained from leaf and nodal explants on MS with different concentrations of BAP in combination with IAA/IBA or IBA alone. Among all the combinations, BAP and IBA exhibited maximum regeneration. High frequency of multiple shoots (89%) was obtained on BAP (2.0 mg/l) and IBA (1.5 mg/l) in nodal explants. Maximum mean shoot length of 6.8 ± 0.33 cm was obtained in nodal explants cultured on BAP (1.0 mg/l) + IBA (0.5 mg/l), followed by leaf explants with 6.7 ± 0.47 cm on BAP (3.0 mg/l) + IAA (2.5 mg/l). The highest frequency of rooting (88.3%) was obtained on NAA (1.0 mg/l) and IBA (2.0 mg/l) with 21.83 ± 0.57 mean number of roots. The well-rooted healthy plantlets were acclimatized with a survival rate of 80%. Inter simple sequence repeat (ISSR) analysis revealed the genetic similarity of in vitro raised plants with the mother plant.
