Arabidopsis thaliana is a common research plant of molecular and cell biological research which has short lifecycle and huge amount of seeds[1]. Gamma ray is one of the important physical mutagens which is widely used inplant genetics and breeding research[2].The purpose of this study is to investigate the dose-effect of ray radiations on the root development ofArabidopsis.Dry seeds were irradiated by rays with the dose range from 100 to 1 600 Gy.
