| Abstract: | Free radicals were studied at room temperature by the ESR spectrum method after wheat seeds were irradiated by the medium energy nitrogen ion beam.It is found that the variation of free radical concentration as total dose has different feature for the penetrated and implanted seeds. The relationship between free radical concentration in wheat seeds penetrated by nitrogen ions and dose rate was also discussed. |
