Isotopic ratios 137Cs/133Cs and concentration ratios 137Cs/K, 133Cs/K, 137Cs/Rb, 133Cs/Rb and K/Rb in fruit bodies of Suillus variegatus were analysed. Variation in ratios 137Cs/K and 137Cs/Rb within genotype was found similar to within whole population. Ranges of variation in ratios 133Cs/K, 133Cs/ Rb K/Rb within individual genotypes are about twice narrower than within whole population.


Keywords: genotype, population, radiocaesium, concentration ratios
