Analysis of endosperm development in plants from contaminated sites (vicinity of the Żelazny Most copper post-flotation reservoir in the Legnica-Głogów Copper District, and the zinc spoil in Katowice-Wełnowiec) showed general similarities in the pattern of endosperm formation in Echium vulgare, but also deviation from typical haustorium structure (~23% frequency), premature degeneration of the haustorium, or degeneration both of the haustorium and endosperm proper (~40%). The most significant irregularities of endosperm development included lower or higher number of nuclei in two cells of the lateral part of the endosperm, lower ploidy level of haustorium nuclei, and cellularization (instead of coenocytic structure) in the lateral cells of the endosperm. Irregularities and degenerative processes presumably resulted from the stress of environment conditions. Because of the nutritive function of those structures, degeneration or atypical structure of the endosperm and its haustorium in some maturing seeds may reduce the fertility of plants colonizing contaminated sites.

Reproduction of Echium vulgare L. was examined in situ at two contaminated sites (Silesia, Poland): a zinc spoil heap in Katowice-Wełnowiec, and the surroundings of the Żelazny Most copper post-flotation waste reservoir. Plants from uncontaminated sites (near Rymanów) were studied as the control material. We compared the reproductive capacity of plants in the stress conditions to that of plants from uncontaminated sites. Degenerative processes and abnormalities found in the reproductive organs of plants from polluted sites, more intensified in the population from Żelazny Most, resulted in lowered fertility of plants. In germination tests on standard soil and from polluted sites, seeds from the control plants had the lowest germination on soil from Żelazny Most, and seeds from Żelazny Most had significantly delayed germination and had higher germination on standard soil than on polluted soil from their site; on the other hand, seeds from Katowice-Wełnowiec had higher germination on waste heap soil than on standard soil. The results suggest that among the populations from polluted sites, the one from Katowice-Wełnowiec is more advanced in selection for tolerance.
