Monitoring the seeds of chronically irradiated native populations of Plantago lanceolata L. The radiosensitivity of seeds

The method of provocative gamma-irradiation was used to study the radiosensitivity of seeds of three first post-accident reproductions of Plantago lanceolata L. within the thirty kilometer zone of Chernobyl. The radiation injury was severer among seeds taken in 1987-1988 from the areas with a higher level of radioactive contamination.
