Abstract

The work is devoted to the problem of protecting plant organisms from acute gamma radiation. As an object of study, an aquatic plant small duckweed (Lemna minor L.) was chosen, which was irradiated in doses up to 63 Gy. As a radioprotective agent, lignin of wild rosemary (Ledum palustre L.) was tested. In the course of the experiments, the values of biomarkers of plant well-being were established and it was shown that the water-soluble lignin of wild rosemary is not toxic to plant organisms. It has been established that preliminary cultivation of plants in aqueous lignin-containing media can reduce the level of damage and increase the length of the roots of irradiated plant organisms, which indicates the manifestation of adaptogenic and radioprotective properties of lignin at the organismic and population levels. For the first time, a hypothesis about the radioprotective potential of lignin was put forward and the possibility of using exogenous lignin to protect plant organisms from acute gamma radiation in high doses was experimentally shown.

Работа посвящена проблеме защиты растительных организмов от острого гамма-излучения. В качестве объекта исследования было выбрано водное растение ряска малая (Lemna minor L.), которую подвергали облучению в дозах до 63 Гр. В качестве радиопротекторного средства был апробирован лигнин багульника болотного (Ledum palustre L.). В ходе экспериментов установлены значения биомаркеров благополучия растений и показано, что водорастворимый лигнин багульника не токсичен для растительных организмов. Установлено, что предварительное культивирование растений в водных лигнинсодержащих средах позволяет снизить уровень повреждений и увеличить длину корней облученных растительных организмов, что свидетельствует о проявлении адаптогенных и радиопротекторных свойств лигнина на организменном и популяционном уровне. Выдвинута гипотеза о радиопротекторном потенциале лигнина и экспериментально показана возможность использования экзогенного лигнина для защиты растительных организмов от острого гамма-излучения в высоких дозах.
