Dry seeds of Stevia were implanted by 35-150 keV nitrogen ion with various doses. The cytological effect on M1 was studied. The results showed that nitrogen ion beam was able to induce variation on chromosome structure in root tip cells. The rate of cells with chromosome aberration was increased with the increase of ion beam energy and dose. However there was no significant linear regression relationship between ion dose and aberration rate. The cytological effect of nitrogen ion implantation was lower than that of gamma-rays
