Corn seeds were irradiated with 80.55 MeV/u carbon ion beams and 82 MeV/u ~(36)Ar~(18+)ion beams. The experimental results showed that the rates of emergenee all took the trend lowered gradually along with the doses increased.An optimal range of doses was favorable for the growth of corns.Maize seeds were irradiated by 10,15,20,25 and 30 Gy ion beams,respectively.Compared to other maize seeds,the corn seeds irradiated with ions in the range of 10～20 Gy were found favorable characters such as higher e-

Corn seeds were irradiated with 80.55 MeV / u carbon ion beams and 82 MeV / u ~ (36) Ar ~ (18+) ion beams. The experimental results showed that the rates of emergenee all took the trend started along with the increasing . An optimal range of doses was favorable for the growth of corns. Maize seeds were irradiated by 10, 15, 20, 25 and 30 Gy ion beams, respectively. Compared to other maize seeds, the corn seeds irradiated with ions in the range of 10 ~ 20 Gy were found favorable characters such as higher e-
