Abstract :Seed deterioration is considered to begin at physiological maturity and continues during harvesting and storage. It's influenced by genetic, production and environmental factors. Genetic differences are between cultivars for the ability to sustain good seed quality in nonsuitable environments. Besides that these differences can be occur with the effect of stress. The subject of seed vigour is for seed technology and physiology. The study aim was to determine the seed deterioration of Hordeum vulgare L. seed lots with accelerated aging tests in three different periods. Seven different proprietary barley varieties used in the study were obtained from İzmir Ege Agricultural Research Institute. Our m ethods which used for this purpose; at 30 °C (7 day)  germination and seedling test, accelerated aging test with 24-48 and 72 hours at 45 °C and EC test at 20 °C in 24-48-72 hours were made. Observations made at the end of the treatments; seed moisture content (%), normal-abnormal germination rate (%), mean germination time (day). The germination rates of varieties are close to each other and very high. However, at the end of the vigor test of the aged cultivars, significant differences were observed especially in the mean germination time and seedling emergence performance. In EC measurement results, the best value was taken from Sancak variety.
