Özet:It is essential to use quality seeds for the production of sugar beet (Beta vulgaris L.) with high yield and quality standards. Sugar beet seeds are stored either raw (unprocessed) or processed form. Logetivity of seeds in storage is affected by cultural processes applied during seed production, environmental factors, genetic characteristics of the variety, chemical content of the seed, and seed maturity status. In this study, the effects of storage period of 17 years on germination of stored sugar beet seeds produced in Turkey were investigated. When harvested, seeds with a moisture content of 12% were stored in storage whose temperature and humidity parameters were not controlled. While storage temperatures were the lowest in December (1 oC), January (2 oC) and February (3 oC), it increased to 29 oC in July and August. The relative humidity of the storage was 69% in January and 22% in July and September. The highest germination rate of raw seeds, which were stored for 17 years after production was obtained as 92% from the lots 3, 6 and 7 and 93-95% in processed seeds of these 3 lots. In the greenhouse tests of stored seeds, the values of germination rates in all seed lots were obtained between 82% and 94%. Field emergence rates of seeds showed a parallelism with laboratory and greenhouse germination tests, germination rates varying between 88% and 90%.
