Abstract: Experiments were conducted to determine the effect of diluted sea water on the growth and flowering of the‘Coral’carnation cultivar. Nine young plants were planted in a wooden container (40×40×12cm) filled with sand or soil. Sea water diluted with Hoagland′s solution, and also tap water was used for both sand and soil cultures. Each solution contained 0, 100, 250, 500, 1, 000, 2, 000 and 3, 000ppm Cl. Treatments were continued from April 10 to flowering. Salt injury was not found at 0 and 100ppm Cl. Plant height and top fresh weight of the flowering plant grown in sand and soil decreased above 250ppm Cl of sea water, and flowering was delayed above 500ppm Cl. The degree of injury was intensified as sea water was raised from 250 to 3, 000ppm Cl. Dieback on the leaves appeared above 500ppm Cl in sand culture and above 1, 000ppm Cl in soil culture about 45 days after the beginning of treatment. Generally the injury was more severe in sand than in soil cultures, and was highly correlated with Mg and Na in the leaves, and with Cl in the leaves, stems and petals. With increasing sea water concentrations, the total N, P and K in the leaves decreased, and the Cl, exchangeable Mg and Na, and EC values of the sand and soil increased.
