In this research, we discussed the sensitivity and optimum irradiation dose of 3 species of halophytes which were irradiated by the carbon ion beam and the electron beam. Dry seeds of three types were irradiated by different parameters of carbon ion beam and the electron beam. This research was investigated the effects of germination and seedling growth of three halophytes irradiated by carbon ion beam and the electron beam to provid theoretical basis for halophytes superior breed.The main conclusion of thi...
