Reproductive processes including male and female lines, embryo and endosperm development were studied in\udCardaminopsis arenosa (syn. Arabidopsis arenosa) growing on two metalliferous sites (Bukowno and Bolesław,\udS. Poland), rich in Zn, Pb, Cd and other metals. Disturbances of developmental processes and necroses observed\udin anthers and ovules influenced plant fertility and seed set of plants from both metal-polluted sites. In anthers,\uddisturbances and necrosis during male meiosis and pollen development occurred at low frequency (4–5%).\udPollen grain viability was very high, reaching over 90%. In ovules the frequency of abnormal meiosis, female\udgametophyte developmental disturbances and necrosis was high, 23.5–28% depending on site. The polluted environment\udalso affected embryo and endosperm. Necrosis of whole generative structures decreased plant fertility.\udThis study indicates that the range of disturbances and necroses in embryological structures and processes (at\udgametophyte level) gives a set of useful characters to determine plant tolerance to stress, complementary to many\udtolerance characters at the sporophyte level of plant ontogenesis
