ACCUMULATION OF CS-134 IN THE OAT DEPENDING ON SOIL CHARACTERISTICS
2005, 6 (1) p. 91-94
Vegetation pot experiments with spring oats, cultivar Obrazcov Chifl ik – 4, were carried out. The plants were grown on four different soil types, typical for Bulgaria: Haplustoll, Udolls, Ustifl uvents, Albaqualf /USA. The soils were contaminated with the Cs-134. It was concluded that the radio-caesium accumulates unevenly in the different plant organs, as its highest concentration was found in the leaves and lowest in the grains of the researched culture. Substantial differences were discovered in the accumulation of caesium –134 in the plants, depending on the soil differences. According to the accumulation of the radio-caesium in the plants, the different soils can be arranged as follows: Albaqualf > Vdolls >Ustifl uvents > Haplustoll.
