Effects of Irrigation Water Salinity on Germination of Old and New Barley (Hordeum vulgare conv. distichon) Species

The old (Cumhuriyet) and new (？nce04) developed varieties of the two rows of the barley, one of the first cultivated plants, were subjected to the germination test under saline irrigation water conditions. Irrigation water Electrical Conductivity (ECi) values are 0, 2, 4, 6, 8, 12 and 16 dS/m and Sodium Absorption Rate (SAR) is prepared to be less than 3. According to the analysis of the variance made to the data obtained at the end of the study, irrigation water salinity, the rate of germination and the germination power of these barley varieties were determined to be effective on the level of 5% importance. In spite of increasing EC value in irrigation water, the germination rate and the germination power of the barley varieties decreased. Result of this study, it has been determined that Ince 04, new development kind of barley, is resistant salinity water about 12 dS/m. Whereas, Cumhuriyet, old kind of barley, is resistant of salinity water about 8 dS/m
