Abstract:
An efficient micropropagation protocol was developed using lateral shoot explants of Aloe vera. Both
shoot induction and elongation were better on MS medium supplemented with 4mg/l BAP + 0.2mg/l
NAA + 1g/l PVP. All cultures showed shoot regeneration in this medium with 16 shoots/explant. Addition of 1g/l PVP was ineffective for controlling phenolic browning of explants and culture discoloration.
However, more adventitious buds (21.5 shoots/explant) developed on MS medium supplemented with
4mg/l BAP + 0.2mg/l NAA + 1g/l PVP+10mg/l citric acid+0.5g/l activated charcoal. Browning of explants was minimized in this medium and elongation of micro-shoots and the growth of the plantlets
were also better. Further elongation and rooting of micro-shoots were obtained when sub-cultured on
to MS basal medium containing 0.5g/l activated charcoal and 100% of the survival of rooted plantlets
was observed after acclimatization. Therefore, the above protocol could be effectively used in rapid micropropagation of elite plants of Aloe vera
