Abstract
Adhahpuspi (Trichodesma indicum, Family – Boraginaceae) is a cross-pollinated species. Its complete regeneration was accomplished through in vitro techniques. The zygotic embryos placed on MS (Murashige and Skoog) medium fortified either with kinetin, BA (N6-benzyl Aminopurine) or NAA (α-naphthalene acetic acid) produced callus and adventitious shoots; whereas those placed on MS medium supplemented with 2,4-D (2,4-dichlorophenoxyacetic acid) formed callus. On subculture, the nodal pieces produced axillary shoots that were suitable for further propagule proliferation. Rhizogenesis occurred in 60% micro shoots treated with IBA (indole-3-butyric acid) pulse. The regenerated plants successfully acclimatized and started flowering in green house maintained at 30 ± 2ºC temperature and 70% RH.
Key words: Acclimatization, callus, caulogenesis, micropropagation, pulse treatment.
