Abstract: Low specific radioactivity (7.4kBq/ml) 211At treating pollen and stigma can obviously affect morphological structures and physiological functions of pollen, stigma and ovule or embryo sac cells, and cause injury. Results showed that because of the radiation effects the seed setting rate of rice was decreased, and the development of some embryos were affected and others became abnormal.
