Abstract: The study showed that the concerntration of 6-BA, NAA and Vitamin C affected plantlet propogation coefficients ofWasabi through optimization regression analysis. As a result, the suitable combination was selected, the proliferation coefficient might increase to 6.8380 when treated byMS medium with 6-BA
1.2504 mg/L and Vitamin C 1.9668 mg/L. In rooting culture, 1 /2MS medium or 1 /2MS with 0.01mg/L NAA were suitable for root development and growth, and rooting frequency reached above 90%. In acclimatization, the results showed that strong plantletswithout rootingwere fit for culture out of door with around 80% rooting frequency, therefore, production cost of wasabi seedlings decreased greatly without rooting phases.
