[An analysis of the genetic sequelae of the contamination of winter rye crops by the radioactive fallout from the Chernobyl Atomic Electric Power Station].

Changes of important cytogenetical indices, like an yield of aberrant cells and their burden by damages, with dose value was shown at the study of genetical consequences of winter rye contamination with radioactive Chernobyl NPP fallout at the acute phase (the vegetation period of 1986). Larger genetical efficiency was demonstrated for low dose rate radiation. Stimulation of morphometric indices in rye seedlings characterizing their survival on the earlier stages of ontogenesis was observed together with significant increase of the cytogenetical damages.
