Standardization of micropropgation techniques for Aloe vera: a pharmaceutically important plant

Aloe vera (Syn Aloe barbadensis Mill.), a medicinal plant, has a great potential in cosmetic and drug industry due to presence of more than 200 bioactive compounds. Natural propagation of Aloe vera, by means of suckers, is very slow and insufficient to meet the increasing demand of pharmaceutical and cosmetic industries. Shoot tip was used as an explant for in vitro regeneration of Aloe vera. Explants were disinfested with the use of 0.1% mercuric chloride and 0.5% sodium hypochlorite, and washed thoroughly with autoclaved distilled water. Solid MS medium was used with addition of different concentrations of 6-benzyl aminopurine and α-naphthalene acitic acid. After 7 weeks of inoculation, greatest number of shoots (11.18) and highest shoot length (12.15cm) were found in MS medium supplemented with 0.5 mg l-1 6-benzylaminopurine (BAP) along with same concentration of α-naphthalene acitic acid (NAA). Best rooting (84.67%) was found in medium supplemented with 1.5 mg l-1 of indole butyric acid (IBA). The rooted explants were then gradually acclimatized and shifted to green house.
