Radioecology of Picea excelsa (L.) Lam

Jan Sarosiek, Irena Iwen

Abstract


Within the area of the radiation anomaly near Kowary (Sudeten Mountains) the spruce (Picea excelsa) occurs in habitats with natural soil gamma radiation within 0.05-1.48 mR/h. By way of detailed ecological analysis 5 stenotopic habitats of spruce development were selected differing in radiation intensity. In these habitats the intrapopulation variability, radioactivity and ecological properties of the Picea excelsa populations were investigated. It was demonstrated that radiation within the above mentioned range is an essential ecological limiting factor, conditioning ecotypic differences in Picea excelsa. The limiting influence of radiation is manifested in a high frequency of development anomalies in the spruce population.
