The results of the cytogenetic monitoring of the species of angiosperm plants growing in the area of the radionuclide contamination after the accident at the Chernobyl Atomic Electric Power Station

Kordium EL, Sidorenko PG

 




Results of investigations of meiosis in microsporogenesis, sporads and pollen grains as well as mitosis in root meristematic cells in 94 species of angiosperms (from 28 families) growing in different ecological conditions in the zone with higher radionuclide pollution after the Ch.NPS accident are present. The low percentage (0.5-2.0%) of anomalies on investigating parameters has been revealed in the majority of species, only in certain species (8-10%) the correlation between an increase of the number of anomalies and an increase of the gamma-radiation level was shown. The data obtained make evident the resistance of the seed reproduction system in higher plants to chronic irradiation by the low doses of ionising radiation.
