Strawberry is very weak in the salinity and there is seldom the saline irrigation of the strawberry. In this study, strawberry (Sagahonoka) plants were cultivated hydroponically with 3 different concentrations of diluted seawater. Salinity treatments consisted of three tanks (eqiuvalent to electrical conductivity of 1. 0 (nonsalinized control), 1 .2, 3.0 mS/cm respectively. The effect of salinity treatment came out after the treatment for the growth of leaves in about the week. Salinity levels of 1.2 and 3.0 controlled tanks were controlled with adding sea water. Salinity did not significantly affect sugar content Lycopene-eguivalent concentration was high only in the 3.0 controlled tanks. Salinity did not affect Polyphenols concentration. Concentrations of Na, Br of strawberry fruits increased at high salinity. However, the concentration of Ca decreased at high concentration.
