Для исследования было выбрано отдельно стоящее дерево возрастом 34 года и высотой 17 м. Была проведена эксгумация корневой системы квадратом 4×4 м со штамбом в центре. Для 3D-сканирования было проведена оцифровка на 360° с трех сторон корневой системы с помощью ручного 3D-сканера Artec Evo. В результате сканирования была реконструирована 3D-модель корневой системы с 251 отдельным корнем с диаметром от 0,5 см и более. Анализ 3D-модели показал, что общая протяженность корневой системы составила 18408 см, а средняя длина одного корня – 74,5 см. Диаметры корней варьировались от 0,5 до 18 см, преобладали значения в 1–3 см. Морфометрическая структура корневой системы включала четыре основных крупных корня с диаметрами 14–22 см, исходящих от ствола дерева и направленных перпендикулярно друг другу, к которым примыкали корни условного 2-го и 3-го порядков. В диагональном направлении выделялись участки повышенного роста корней разных порядков. В целом полученные результаты соответствуют представлениям о корневой архитектонике этого вида дерева.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of a study of the Picea abies root system in the middle taiga region using 3D scanning. A single 34-year-old tree 17 m high was selected for the study. The root system was exhumed as a 4×4 m square with a rootstock in the center. For 3D scanning, 360° digitalization was performed on three sides of the root system using an Artec Evo handheld 3D scanner. As a result of scanning, a 3D model of the root system was reconstructed with 251 individual roots with a diameter of 0,5 cm or Analysis of the 3D model showed that the total length of the root system was 18,408 cm, and the average length of one root was 74.5 cm. The root diameters varied from 0.5 to 18 cm, but 1–3 cm predominated. The morphometric structure of the root system included four main large roots with diameters of 14–22 cm, originating from the tree trunk and directed perpendicular to each other, to which the roots of the conditional 2nd and 3rd orders were adjacent. In the diagonal direction, areas of increased growth of roots of different orders were distinguished. In general, the obtained results correspond to the ideas about the root architectonics of this tree species.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ель европейская</kwd><kwd>корневая система</kwd><kwd>3D-сканирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>European spruce</kwd><kwd>root system</kwd><kwd>3D scanning</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации (тема № 075-03-2023-128)</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">Демидов И.Н., Лукашов А.Д.
