Resumen
Plant regeneration via callus culture was achieved using immature flower buds of mature tree of Azadirachta indica A. Juss on semi-solid MS medium enriched with 9.05µM 2,4-D + additives. The regenerated callus were amplified on lower concentration of 4.52 µM 2,4-D + additives for micro-shoot regeneration study, the best micro-shoot regenerated from callus was achieved on MS medium supplemented with 8.88 µM BAP with 3.78±0.50 numbers of shoot and 3.66±0.57 shoot length. The micro-shoots were amplified on 8.88 µM BAP+ 0.27 µM NAA with 5.22±0.53 numbers of shoot and 4.62±0.59 shoot length respectively. Micro shoot were successfully rooted on MS medium supplemented with IBA 4.92 µM with rooting percent (100%), 4.35±0.22 root number and 3.95±0.23 root length. The callus derived plantlets were hardened in vitro and ex vitro and acclimatized in poly house followed by agro-shade house. The efficiency of the protocol will be helpful for propagation of Azadirachta indica plants on a mass scale.
