[The ultrastructural organization of pine needles after radiation exposure]
Radiobiologiia
|January 1, 1993
Abstract:
Pine assimilative tissue was studied in the region of Chernobyl Power Plant accident the 1986-1988. With radiation doses of 8-11 Gy pine needle was viable inspite of the significant structural changes in cell organelles. With doses of 20-25 Gy the inner structure of mesophyll cells was impaired. High radiosensitivity was displayed by mitochondria and chloroplasts where irreversible destruction of membrane systems occurred.
