| Abstract: | The influences of a single rtg irradiation dose (14 mGy) on some quantitative signs in dependence on the body length was studied in the experimental fishes Barbus conchonius and B. tetrazona. The values of all followed signs increased positively due to the body length growth. The irradiation with the abovementioned dose in the given conditions had relative small influence on the growth course of the chosen quantitative sign values in the control and irradiated fishes of both species is the same (the regression lines are in good agreement, resp. they are parallel). The statistically significant difference was stated only between the irradiated the non-irradiated groups of B. tetrazona due to the head height (the regression lines are divergent). |
