The following lines were selected as study objects: <italic>abi3-8</italic> with a mutation in the ABI3 gene and with reduced sensitivity to the natural form of abscisic acid and <italic>aba3-1</italic> genotype with a mutation in the ABA3 gene and a reduced level of endogenous abscisic acid. Wild type Col-8 was used as a control. To study the effect of γ-radiation on various aspects of seed germination (germinability, germination time and rate, synchrony of germination, etc.), the germination kinetics was assessed using the Germinationmetrics package for the R programming environment. Control and irradiated seeds (radiation source – <sup>60</sup>Co) were grown on half-strength Murashige-Skoog medium under controlled conditions. Germination was assessed during the first six days after transfer to the phytotron by the rupture of the endosperm and the appearance of a root. In total, three independent experiments were carried out with three biological replications in each. A more pronounced effect of γ-radiation at a dose of 150 Gy on all studied genotypes was noted. Germination clustering showed that the distribution of the percentage of seed germination by day depends more on the genotype than on the dose of exposure. The best indicators of germination, speed and time interval between germination of 10% to 90% of seeds were noted for non-irradiated seeds of the <italic>abi3-8</italic> line. The results obtained and a comparative analysis with previously published data suggest that the assessment of germination kinetics using the Germinationmetrics package for R is a clear and quite informative tool for studying the effect of ionizing radiation and other abiotic factors on various aspects of seed germination.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324411168">Проведен анализ динамики прорастания семян модельного растения <italic>Arabidopsis thaliana</italic> после воздействия γ-излучения в дозах 50, 100 и 150 Гр. Объектами исследования выбраны линии: <italic>abi3-8</italic> с мутацией в гене <italic>ABI3</italic> и со сниженной чувствительностью к природной форме абсцизовой кислоты и генотип <italic>aba3-1</italic> с мутацией в гене <italic>ABA3</italic> и пониженным уровнем эндогенной абсцизовой кислоты. В качестве контроля использован дикий тип Col-8. Для изучения влияния γ-излучения на различные аспекты прорастания семян (всхожесть, время и скорость прорастания, синхронность прорастания партии семян) проведена оценка кинетики прорастания при помощи пакета Germinationmetrics для среды программирования R. Контрольные и облученные семена (источник излучения – <sup>60</sup>Co) выращивали на питательной среде Мурасиге–Скуга половинной концентрации в контролируемых условиях. Прорастание оценивали в течение первых 6 сут после переноса в фитотрон по разрыву эндосперма и появлению корешка. Всего проведены три независимых эксперимента с тремя биологическими повторностями в каждом. Отмечено более выраженное влияние γ-излучения в дозе 150 Гр на все исследуемые генотипы. Кластеризация всхожести показала, что распределение процента прорастания семян по дням больше зависит от генотипа, чем от дозы воздействия. Лучшие показатели всхожести, скорости и временного интервала между прорастанием 10 и 90% семян отмечены у необлученных семян линии <italic>abi3-8</italic>. Полученные результаты и сравнительный анализ с ранее опубликованными данными позволяют утверждать, что оценка кинетики прорастания при помощи пакета Germinationmetrics для R – наглядный и достаточно информативный инструмент для изучения влияния ионизирующего излучения и иных абиотических факторов на различные аспекты прорастания семян.</p></trans-abstract><kwd-group xml:lang="en"><kwd><italic>Arabidopsis thaliana</italic></kwd><kwd>germination kinetics</kwd><kwd>γ-radiation</kwd><kwd>abscisic acid</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Arabidopsis thaliana</kwd><kwd>кинетика прорастания</kwd><kwd>γ-излучение</kwd><kwd>абсцизовая кислота</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования проведены в рамках Государственного задания “Фундаментальные генетические и биотехнологические исследования для сельского хозяйства” по Программе деятельности ФГБУ “Национальный исследовательский центр “Курчатовский институт”.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Verma V., Ravindran P., Kumar P.
