Поиск эффективных способов ограничения перехода радионуклидов в пищевые цепи и ремедиации загрязненных территорий остается актуальной задачей. Одним из факторов, влияющих на переход 137Cs из почвы в растения, является микробиом почвы. Основная гипотеза данной работы состоит в том, что развитие арбускулярной микоризы (АМ) на корневых системах растений приводит к повышению доступности изотопов цезия для корневого поглощения и увеличивает их накопление в подземных и надземных частях растений. В связи с этим цель работы – выявить роль АМ в корневом поступлении 137Cs из почвы в модельное растение.</p><p>Эксперимент поставлен в условиях микровегетационного опыта, для проведения которого в качестве модельного растения был выбран ячмень обыкновенный сорта Бурштын. Микоризацию корневой системы осуществляли с использованием инокулянта MycoApply SuperConcentrate. Результаты эксперимента позволили впервые показать связь между параметрами накопления и распределения 137Cs в растениях ячменя с уровнем развития АМ в корневой системе растения. Развитие микоризной инфекции в корневой системе ячменя привело к росту коэффициента накопления 137Cs в надземных органах ячменя в 1,8–2,6 раз по сравнению с контролем. При этом наблюдается тенденция к снижению удельной активности радионуклида в корневой системе.</p></abstract><trans-abstract xml:lang="en"><p>Tests of nuclear weapons, routine and accidental releases of radionuclides from nuclear fuel cycle facilities, on one hand, and the long half-life decay time of 137Cs have led to significant levels of accumulation of this radioactive isotope in environmental objects in vast territories, which can have a negative impact on biota and public health. The search for effective methods to limit the transfer of radionuclides into food chains and remediate contaminated areas remains a pressing issue. One of the factors influencing the transfer of 137Cs from soil to plants is soil microbiom. The main hypothesis of this study is that developing arbuscular mycorrhizaon plant root systems leads to increasing the availability of cesium isotopes for root absorption and enhances their accumulation in underground and aboveground parts of plants. Therefore, the aim of this study was to determine the significance of arbuscular mycorrhiza in the root uptake of 137Cs from soil into a model plant.</p><p>The vegetative experiment was conducted with barley variety Burshtyn chosen as a model plant. Mycorrhization of the root system was performed using the MycoApply SuperConcentrate inoculant. The results of the experiment allowed for the first time to demonstrate the relationship between accumulation and distribution parameters of 137Cs in barley plants with the level of arbuscular mycorrhiza development in the plant root system. Developing mycorrhizal infection in the barley root system increased the transfer factor of 137Cs from soil to the aboveground organs of barley 1.8–2.6 times compared to the control.</p><p>At the same time, there is a tendency towards a decrease in the activity concentration of the radionuclide in the root system. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>арбускулярная микориза</kwd><kwd>ячмень обыкновенный</kwd><kwd>почва</kwd><kwd>цезий-137</kwd><kwd>коэффициент накопления</kwd><kwd>коэффициент транслокации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>arbuscular mycorrhiza</kwd><kwd>barley</kwd><kwd>soil</kwd><kwd>cesium-137</kwd><kwd>transfer factor</kwd><kwd>translocation factor</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта БРФФИ Б16К-053.</funding-statement><funding-statement xml:lang="en">The work was supported by grant BRFFR B16K-053.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Steiner, M.
