Sažetak
Pot experiments with different cultivars of beans, peas and soya spread in Bulgaria were carried out. The following cultivars were analyzed: beans - cultivars Plovdiv 10, Plovdiv 164 and Dobrudjanski 7; peas - cultivars Mira, Iskar, and Pulpudeva; soybeans - cultivars Pavlikeni 121, S – 134, and Hodzon. The plants were grown on the soil type Haplic chernosem, contaminated with the radionuclide Cs-134. It was established that the radiocesium was accumulated unevenly in the different plant organs, and the highest concentration was recorded in the leaves, while the lowest was found in the seeds of the studied crops. Cultivar differences with regard to the absorption of the radionuclide by the plants were established. The
lowest degree of accumulation of Cs-134 was found in beans –cultivar Dobrudjanski 7, in peas – cultivar Mira, and soybeans – cultivars Hodzon and S 1346. No considerable cultivar differences were observed with respect to the radionuclide accumulation in all
studied crops. A comparatively weaker extraction and accumulation of Cs134 was recorded in all above-soil organs of the bean plants, in comparison with the remaining crops.
