Abstract

The influence of man-made dust pollution on the changes of the physiological and biochemical characteristics, and their heterogeneity (variability), as well as on the radiostability of seed progeny of L. Apetalum was investigated.
It was shown that a higher degree of man-made dust pollution of growing place of parent plants had no impact on the level of radiostability of seed progeny, compared with the control, despite the higher value of antioxidant status in their seed progeny, which is probably a consequence of reduced variability of the investigated characteristics.
