Abstract

The aim of this study was to establish the nutrient management practice for the soilless culture of Bupleurum falcatum L., which is the original plant source of the crude drug “Saiko” used for Kampo medicines. The seedlings of B. falcatum were transplanted to PVC tubes filled with granulated rockwool and supplied with quarter-, half- or full-strength Otsuka B nutrient solution, respectively. Eleven-month-old plants were harvested, and the growth and saikosaponin (SS) contents were measured. The mineral concentrations in the plant were also measured to estimate the plants’ nutrient absorption. The top dry weight, maximum leaf area and plant height of plants grown in full-strength solution were lower than those of plants grown in the other treatments. There was no difference in the root dry weight among treatments, and the top to root ratio on a dry weight basis was lowest in the plants grown in full-strength solution. Saikosaponin content per g of root dry matter was not affected by solution concentration. However, saikosaponin yield from plant root was highest from plants grown in full-strength solution. Although the mineral concentration tended to be higher in plants grown in half- and full-strength solutions than in those grown in quarter-strength solution, a similar trend was observed in the ratio of nutrients calculated from those concentrations. The appropriate ratio of the major elements in the nutrient solution estimated from the result was N:P:K:Ca:Mg＝6.5:4.7:8:1.3:1.8 (me L^-1).
