Abstract
The dry and watersaturated seeds of Arabidopsis thaliana were irradiated by H+ions with 6.5 MeV in atmosphere. The ion fluence used in this experiment was in the range of 4×109 —1×1014 ions/cm2. According to the structure of the seed and TRIM simulation， the ions with the energy of 6.5 MeV can penetrate the whole seed. The experiment shows that the fluenceresponse curves for the dry seeds and watersaturated seeds had distinct shoulders and reduced rapidly. The experimental results show that the waterimbibed seeds were more sensitive than the dry seeds and the reason is from free radicals reaction. A model has been constructed, and primely simulates the experiment data.
