Description

The relationship between the concentration of a nutrient solution and the growth of Elatostema involucratum Franch. & Sav., hydroponically cultured from bulbils, was investigated. Transplants of E. involucratum were supplied with 0.25 units (low concentration) or 0.5 units (high concentration) of Enshi nutrient solution. However, in the high concentration treatment, the concentration of the Enshi nutrient solution from 0 to 14 days after transplantation was 0.25 units. The length of the main stem and internodes with the low concentration treatment was significantly longer than that with the high concentration treatment at 49 days after transplantation. Changes in the number of nodes after transplantation were not significantly different between the low and high concentration treatments. The stem diameter with the low concentration treatment was significantly larger than that with the high concentration treatment at 64 days after transplantation. In addition, the top and root fresh weight with the low concentration treatment was significantly higher than that with the high concentration treatment at 64 days after transplantation. The number of stems from bulbil and the number of lateral shoot were not significantly different between the low and high concentration treatments. In addition, the growth of transplants cultured with 0.13 or 0.25 units after transplantation was similar. Therefore, a suitable concentration of a nutrient solution in the hydroponic culture of E. involucratum was considered to be 0.25 units or less.
