英文摘要In order to investigate the biological effects of heavy ion radiation at low closes and the different radiosensitivities of growing and non-growing plants. rice at different lift stages (dry seed, wet seed and seedling) were exposed to carbon ions at closes of 0 02, 0.2, 2 and 20 Gy. Radiobiological effects on survival, root growth and mitotic activity, as well as the induction of chromosome aberrations in root meristem. were observed The results show that radiation exposure induces a stimulatory response at lower close and an inhibitory response at higher dose on the mitotic activity of wet seeds and seedlings Cytogenetic damages are induced in both seeds and seedlings by carbon ion radiation at doses as low as 0.02 Gy Compared with seedlings. seeds are more resistant to the lethal damage and the growth rate damage by high doses of carbon ions, but are more sensitive to cytogenetic damage by low closes of irradiation Different types of radiation induced chromosome aberrations are observed between seeds and seedlings. Based on these results, the relationships between low close heavy ion-induced biological effects and the biological materials are discussed.
