Research Abstract	Sodium exclusion by roots is important for salinity tolerance of rice. In the presence study, the cyanide resistant respiration in rice was investigated whether it relate to the sodium exclusion by roots through the cytoplasm pH adjustment. As the result, the cyanide resistant respiration in rice related to the sodium exclusion in root, but the contribution in the sodium exclusion was low compared to the varietal difference.
