Abstract: Objective: To study the different concentrations KAA treatment on the survival rate of induced flax, linen-induced search for the best KAA survived concentration. Methods: Four different KAA concentration of media on young flax shoot tip, stem tissue culture. Results: in other factors the same circumstances, KAA content of 0.7 mg / L of the medium with linen explants induced the highest survival rate. In addition, the survival rate with the KAA linen increasing concentration increased
