Abstract

This study was conducted to clarify the effects of the different concentration of the nutrient solution on the early growth and the nutritional contents of hydroponically grown Aster koraiensis, Hemerocallis fulva and Plantago asiatica at 70 days after transplanting in perlite culture. Balanced nutrient solution formulated by Japanese Horticultural Experiment Station was used as the standard concentration of the nutrient solution. Overall plant growth of Aster koraiensis and Hemerocallis fulva such as plant height, stem diameter, number of loaves, fresh and dry shoot and root weight were significantly increased in 1.5 times concentration of nutrient solution. Shoot and root fresh and dry weight of hydroponically grown Plantago asiatica were significantly increased in the higher concentration of the nutrient solution, however, number of loaves and root length were significantly increased in the standard and the lower concentration of the nutrient solution. The highest contents of calcium, magnesium and sodium in plants were shown in Aster koraienxis which were grown in the 1.5 times concentration of nutrient solution, and Hemerocallis fulva and Plantago asiatica in 0.25 times of that. The contents of potassium in Aster koraiensis and Hemerocallis fulva were significantly increased when the plants were grown in the 0.5 times concentration of the nutrient solution, and that in Plantago asiatica in the 1.5 times concentration of the nutrient solution. The contents of phosphoric acid in plants as affected by the different species of Namul and the different concentration of the nutrient solution were not significant.

나물자원의 수경재배시 양액농도가 생장 및 무기물함량에 미치는 영향을 조사하고자 벌개미취, 원추리 및 질경이를 펄라이트 배지에 추식하여 70일간 재배 한 후 생장정도와 무기물 함량을 분석하였다. 벌개미취와 원추리의 초장, 줄기직경, 잎의 수, 신선중 및 건물중은 1.5배액 처리구에서 확연하게 우수한 결과를 나타내었다. 질경이의 지상부와 지하부 생체중 및 건물중 등은 양액의 농도가 0.2재액에서 1.5배액으로 증가할수록 증가한 반면, 엽수와 근장은 0.5배액과 표준농도에서 가장 높은 것으로 나타났다. Ca Mg 및 Na 함유량은 벌개미취의 경우 1.5배액에서, 원추리와 질경이는 0.25배액에서 가장 많았다. K 함량은 벌개미취와 원추리는 0.5배액에서, 질경이는 1.5배액에서 가장 많았다. $P_2O_5$는 나물종류 및 양액의 농도에 따른 차이가 거의 없었다.
