1. Ethyl methanesulphonate (BMS)-treated barley seeds stored at 30 % water content for 1 – 4 weeks are capable of recovering from the mutagen induced injury. The level and speed of the recovery depends on the EMS dose and storage period. Seeds treated with extremely severe EMS doses reducing the% of germination to 5 – 10 % cannot recover from the induced injury. 2. Due to a 1 to 6 weeks storage of EMS-treated seeds with 20 % water content the amount of induced injury increases in dependence on the applied EMS dose and storage period. Doses of EMS, reducing the seedling height in the M1 generation to 90 – 95 % of the control reveal no storage after-effects. 3. Storage of X-ray exposed seeds at 20 % or 30 % water content did not result in any significant changes in the yield of induced genetic damage.
