Effect of acute -irradiation (Co) on morphological peculiarities of microcystic aeruginosa Kuetz. Elenk. and Anabaena cylindrica Lemm

It is shown, that acute γ-irradiation with lower-than-lethal doses may cause growth inhibition and development arrest in blue-green algae in the culture; the shift of their orthomorphogenesis; trichome fragmentation, as well as anomalous morphological structure emergence. The degree of these radiation effect manifestation changes in time and depends on the radiation dose. It is proposed to use data on the frequency of the occuring anomalies in the maximum manifestation period in the course of development of the additional Cyanophyta trichomal form radiosensitivity test
