Abstract
This experiment was investigated to effect of divided rhizome size and medium type on survival rate and growth of wasabi for 60 days in controlled growth room. In divided rhizome size of 5mm above, survival rate was 100% and their growth (plant height of 12cm and leaf number of 3${\sim}$4 per plant) was good at 30 days after wrapped-sphagnum treatment. Plant height was 20cm above and number of leaves increased in 1-2 per plant at 60 days after treatment. Survival rate and growth didn't show any effect on plant regulator of root-tone. In inorganic media (saprolite and aerated light stone) treatment, survival rate of wasabi in divided size of 5${\sim}$10mm showed 83% or above at 30 days in deep flow culture. Growth did not show significant difference of inorganic support media treatments. Therefore, it is possible for divided rhizome size of 5mm above to do production of seedlings by acclimatize for 30 days in hydroponics under controlled growth chamber.
