In the years 1996, 1997, and 1998 the fractions and subfractions of hordeins and the ontogenetic and morphological characteristics of barley, cv. Orbit cultivated 500 meters from the cooling towers of atomic power plants in Jaslovské Bohunice and Mochovce were studied. In the last year of observation the hordein subfraction composition, ontogenetic and morphological characteristics were analyzed and compared in barley which had been sown and cultivated one, two or three years in the same place. The soil radioactivity and the output of rare gases and aerosols into atmosphere exhibited similar values in both localities inside and outside of the possible influence of the operating atomic power plant in Jaslovské Bohunice. Conclusion can be drawn from this that these factors could not significantly affect our experimental results. Under the given conditions 6 new hordein subfractions were found in the Orbit variety, which were observed in the same biological material grown near Mochovce atomic power plant before its operation had started. It is supposed that the breeding conditions have not caused the observed changes. The new hordein profiles are due to heterozygotic form of the tested Orbit variety. The ontogenetic and morphological changes of the followed characteristics were determined by attributes of the breeding classes.
Key words : barley cv. Orbit, hordein fractions and subfractions, atomic power plant effect.
