Abstract
Pot experiments were carried out with three triticale cultivars spread in Bulgaria - Rakita, TC-210, AD-7291. The plants were grown on two soil types representative for our country - luvic phaeozem /FAO and dystric planosol /FAO. The soil was contaminated with the radionuclide Cs- 134. It was established that the radiocesium is accumulated unevenly in the different plants parts. The highest Cs-134 concentration was found in the leaves and lowest in the seeds.
There are differences in the accumulation of Cs-134 in the plants depending on the soil type on which they were raised. It was determined that the uptake of the radionuclide from plants raised on dystric planosol soil was more intensive with comparison with those raised on soil luvic phaeozem. The highest level of accumulation of the radio Cs was established in cultivar Rakita, and the lowest - in cultivar TC-210 for the two soil types.
