Abstract

This experiment was conducted to study the effect of growth characteristics and yield by different planting density on Wasabia japonica Matsum. in water culture. Plant height, leaf length, petiole length was long in spacious planting $(30{\times}25\;cm)$ and short in dense planting$(30{\times}15\;cm)$. Rhizome width was thick in spacious planting, and was thin in dense planting. Rhizome weight per plant decreased by increasing planting density, but rhizome yield was increased by high planting density. But distribution of rhizome weight did not show significant difference at different planting density.

고추냉이 재식밀도가 생육 및 수량에 미치는 영향을 구명하기 위하며 소식구$(30{\times}25\;cm)$와 밀식구$(30{\times}15\;cm)$로 정식하고 시험한 결과 지상부 생육은 초장, 엽병장, 엽수, 분지수 등 모든 형질에서 소식구의 생육이 양호하였다. 근경의 생육 및 수량에서 개체별 근경은 소식구에서 우수하였으나 10a당 수량은 밀식구에서 높았으며 상품근경중도 많았다. 그러나 상품율은 소식구에서 높았다. 근경장의 분포는 소식구에서는 비교적 큰 12 cm 이상이 50%가 분포하였으나 밀식구에서는 10 cm 이하에 65%가 분포하여 큰 대조를 이루었다. 근경폭의 분포도 이와 비슷하여 소식구에서는 27 mm 이상에 50%가 분포하였고, 밀식구에서는 27 mm 이하에 75%가 분포하였다. 그러나 등급별 분포는 소식구와 밀식구간에 큰 차이가 없었다.
