Abstract

In the territory of the Krasnodar VNIIBZR, the research into 90Sr accumulation in vegetative and generative organs of hazelnuts was carried out in the field. The soil is the leached low-humus superthick- chernozems. As a result of long-term (13 years) research in the food chain “soil-plant” it was established that the hazelnut cultivar has an impact on the accumulation of radionuclides in the studied organs. The bark and timber of the “Ata-baba” variety contain more 90Sr, than the variety of “Louise”, the difference is respectively 1.8 and 1.5 times. The leaves, shell and core of the hazelnut cultivar “Ata- baba”, according to the experimental data, also contain more 90Sr, than the variety “Louise”, i.e. 1.3, 1.7       and 1.3 times respectively. In the buds, the hazelnut cultivar “Ata-baba” contains 1.3 times more 90Sr, than the variety “Louise”. The observations and measurements showed that there was no effect of the listed accumulation of 90Sr on the yield of the studied cultivars.
