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.
