Abstract

Fe-EDTA concentrations of culture solution in hydropnics were changed for improving the quality of herbs, peppermint, sage, perilla (Perilla frutescens Britton), basil, hyssop and Japanese honewort (Cryptotaenia japonica Hassk). Culture solution contained Ca (NO₃) ₂·4H₂O : 45g, KNO₃ : 36g, MgSO₄·7H₂O : 22.5g, NH₄HPO₄ : 6.75g in 45l water. High concentration of Fe-EDTA (0.296g/e) inhibited the growth of these herbs. The high Fe-EDTA (0.296g/l) concentration with peppermint resulted in the higher contents of chlorophyll, o-diphenol, total phenols and free amino acid than the control (0.148g/l).
