This study was conducted to establish the optimal condition for acclimatization from somatic embryos of Eleutherococcus seoulensis. Torpedo-shaped embryos of Eleutherococcus seoulensis were cultured on 1/3 MS and WPM media supplemented with GA₃ (3.0, 5.0 mg/L) for 4 weeks. Plentlets were transferred to 1/2 SH solid medium with 1.0 mg/L GA₃ and 0.2% activated charcoal for shoot and root elongation and them elongated plantlets further developed on 1/2 SH medium for 4 weeks. Developed plantlets further elongated into wellshaped leaf and root system on 1/3 SH medium under ventilation condition for 4 weeks. Plantlets grew normally on 1/3 SH basal medium, were acclimated on various soil. Survival frequency of plantlets was influenced by soil type(peatmoss+perlite, perlite, soil on Nam mountain). The highest survival rate to soil was more than 70% when plantlets were 1/3 SH medium under ventilation condition in Nam mountain soil. These results indicate that the systematic procedure of plant production in Eleutherococcus seoulensis could be practically applicable for mass propagation.
