초록

This study was conducted to investigate thegermination and growth response by Salinities of Spergulariamarina Griseb grown in the western coastal region inSouth Korea. The germination was investigated for 10 daysat temperature 10℃, 15℃, 20℃, 25℃ in order to examinethe germination of Spergularia marina Griseb by NaClconcentration 0.0, 0.3, 0.5, 1.0, 2.0%. The germination ofNaCl concentration 0.0～1.0% was 90% over at 15℃treatment, but the germination of NaCl concentration 2.0%was 0% at all temperature treatments. To identify thegrowth response of Spergularia marina Griseb according tothe salinity, Spergularia marina Griseb was cultivated for8 weeks in Hoagland culture medium and sea water. Innutrient solution culture, growth was best in NaCl 50mMamong 0∼400 mM concentrations and in 0, 12.5, 25, 50,100% of sea water, growth was best in 12.5% (dilution ratiowith fresh water) treatment. Spergularia marina Griseb’sinorganic component contents according to salinity showedthat Na+ content increased, but contents of K+, Ca+, Mg+decreased. As a result, appropriate condition for Spergulariamarina Griseb’s germination is considered to be maintainedat 15℃ and in less than NaCl 1.0% of salinity. Whennutrient solution culture, NaCl 0.3% of treatment level isconsidered to be the optimum salinity
