Effective factors on micropropagation of medicinal plant of Satureja khuzistanica

Satureja khuzistanica Jamzad is an endemic species of Iran. The species is an endangered and valuable medicinal plant. In order to propagate through micropropagation, lateral buds were collected from Lorestan province, region of Pol of Dokhtar. The best treatment of sterilization of the explants was 0.1% HgCl2 for 6 minutes. The best medium for shoot regeneration was MS with BA, 2iP and IBA 0.3, 0.3 and 1 mg/l, respectively. Applying 12 different treatments, the mentioned medium was better than other treatments in term of the coefficient of elongation, leaf elongation and leaf greenness. The best medium for root regeneration was MS with 1 mg/l IBA and 0.1 mg/l NAA. It initiated the highest number of primary and secondary roots. Various combinations of different soils were evaluated for survival during the acclimatization, and sand: soil: peat: perlite at a ratio of 1: 1: 1: 1 showed the highest percentage of survival and growth. The best propagation method of the species was developed and the propagated plants could be transplanted into the habitat of the species.
