Abstract

Pot experiments with different triticale and oats varieties spread in Bulgaria were carried out. Three varieties of triticale (Rakita, TC-210, AD-7291) and three varieties of oats (Obrazcov chifl ik, W-!6 and W-17) were analized. The plants were grown on soil type Dystric planosol /FAO. The soil was contaminated with radionuclide 134Cs. It was established that the radiocesium is unevenly accumulated in the different parts of the plants. The highest 134Cs concentration was found in the leaves and the lowest in the grains. Variety differences of uptake of 134Cs in investigated crops were established. The highest level of accumulation of the radiocesium has been detected in triticale variety Rakita, and in oats variety W-17. It has been determined that the uptake of the radionuclide by plants of the triticale is more intensive then that of by the oats plants.
