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.

분주 크기와 배지 종류가 고추냉이 생존율과 생육에 미치는 영향을 알아보고자 환경이 조절된 생장상에서 60일간 재배하였다. 수태로 감싼 근경 크기(직경) 5mm 이상 분주 묘의 생존율은 100%였으며, 생육(초장 12cm 내외, 엽수 $3{\sim}4$장)은 양호하였다. 생육 60일의 분주 묘는 초장 20cm 이상, 엽수가 $1{\sim}2$장 증가하였다. 루톤 분의제 처리는 생존율과 생육에 효과가 없었다. 배지 종류(마사, 난석)에 따른 직경 $5{\sim}10$mm 크기의 분주 묘를 담액 수경으로 재배하였을 때 83% 이상의 생존율을 보였으며 배지 종류에 따른 생육 차이는 없었다. 따라서 근경 크기 5mm 이상의 고추냉이 분주를 환경이 조절된 생장상에서 30일간 수경재배 방식으로 순화하여 고추냉이 건전 묘를 생산할 수 있다.
