BACKGROUND: We have started a study investigating the effect of radiation on bean seeds since radiation can be used to produce more and higher quality products. MATERIALS AND METHODS: Five groups were formed in this study. In each group, 20, 40, 50 and 60 Gy radiation was applied to the seeds in each group, respectively. No radiation was applied to the in the 5th group (Control group). RESULTS: The earliest germination was seen in 20 Gy and control groups and it was the 3rd day. The latest germination was in the 60Gy group at the earliest on the 8th day and at the latest on the 16th day. CONCLUSION: Because of germination and growth rates with seed radiation done with doses above 60 Gy, these findings should be confirmed with larger studies.
