Optimizing the tissue culture condition for Adenium sp as an imported ornamental plant with a low propagation rate can deliver the way for mass propagation to multiplication of this ornamental plant. So, this research was carried out in a factorial experiment based on a completely randomized design to optimize organogenesis of Adenium abessum and Adenium arabicum during shoot induction, proliferation and root induction experiments. The highest rate of shoot regeneration for Adenium obesum was achieved in MS medium containing 0.5 mgl-1 BA, and for Adenium arabicum was achieved in MS medium containing 0.5 mgl-1 BA in combination with 0.5 mgl-1 TDZ. Organogenesis was more observed as leafy and rooted in A. arabicum and shoot induction in that was longer compare with A. abessum. The result showed that 0.5 mgl-1 BA can be used to prolifered shoots induced in both specie of Adenium. The full strength of free plant growth regulator MS medium supplemented with 0.3% activated charcoal was the best treatment at root induction stage. The plantlet gradually became first adapted in sterile perlite with 1/2 MS concentration and then in the culture media contained soil, vermicompost and perlite.
