Since A.D.512, Dokdo has been a part of territory of Korea. Dokdo is a part of Kyungsang-Bukdo, Ullung-gun, Ullung-up, Do-dong in the Korean administrative district division system. Japan strenuously claims sovereignty for significant economic reasons, including fishery rights, and has adhered to a contradictory position that "Dokdo is Japanese land" since Japan incorporated Dokdo into Japanese territory in 1905.ritory in 1905.

| Three species of Chenopodiaceae, i.e. Suaeda japonica, Salicomia herbacea, Beta vulgaris var. cicla, were investigated to compare the physiological characteristics through inoic balances and osmoregulations under different environmental salt gradients. Plats were harvested in two weeks from treatments with salt gradients (0, 50, 100, 200 and 400 mM NaCl) and mineral nutrition gradients(1/1, 1/5, 1/10 dilutions of Hoagland solution). Plants were analyzed for growth responses, ionic balances, osmolalities, conductivities, glycinebetaine and proline contents quantitatively. Three plants of Chenopodiaceae accumulated slats into tissues unlike some salt sensitive species, and showed unique adaptation patterns to overcome saline environments, i.e. strong growth stimulation for Salicomia herbacea, growth negative tolerance for Suaeda japonica, and growth positive tolerance for Beta vulgaris var. cicla. The absorption of inorganic Ca/sup 2+/ ions was inhibited remarkably due to the excess uptake of Na+ with increasing salinity. The K+ content in plants was significantly reduced with increasing salinity. Total nitrogen content was reduced as mineral nutritions and salinity increased. Conductivity and osmolality increased with increasing salinity regardless of mineral nutritions. The ranges of glycinebetaine and proline contents were 0.2¡2.5 ¥ìM/g plant water and 0.1¡0.6¥ìM/g plant water, respectively. |
