Мурманск. Выявлены признаки ксероморфности листьев B. nana: утолщение верхней и нижней эпидермы, листовой пластинки, губчатой паренхимы. В онтогенезе листьев уменьшается толщина палисадного мезофилла и снижается индекс палисадности. В результате обработки данных однофакторным дисперсионным анализом показано, что техногенное загрязнение влияет на длину палисадных клеток листа B. nana в июне и июле ( p ≤ 0,0005) и не оказывает воздействия в августе ( p ≤ 0,1). Достоверных различий размеров клеток губчатого мезофилла не выявлено, что свидетельствует об увеличении толщины губчатого слоя и листовой пластинки за счет числа периклинальных делений клеток и увеличения объема межклетников. Полученные данные являются подтверждением неспецифической реакции ассимиляционного аппарата берез на действие стрессовых факторов. Онтогенетические изменения показателей мезоструктуры B. nana рассматриваются как адаптивные реакции на техногенный стресс, обеспечивающие снижение транспирации и оптимальный фотосинтез в условиях загрязнения среды арктического города. Карликовая береза может быть использована как объект биомониторинга качества окружающей среды промышленных территорий Арктики и Субарктики.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of studies of indicators of mesostructure in the ontogeny of leaves of dwarf birch (Betula nana L.), which grows under the influence of emissions of industrial enterprises of the city of Murmansk. Signs of xeromorphism of B. nana leaves were revealed: thickening of the upper and lower epidermis, leaf blade, spongy parenchyma. In the leaf ontogenesis, the thickness of the palisade mesophyll and the palisade index decreases. As a result of data processing by analysis of variance, it was found that technogenic pollution effects on the length of palisade cells of the leaves of B. nana in June and July (p ≤ 0.0005) and does not affect in August (p ≤ 0.1).There were no significant differences in the sizes of cells of the spongy mesophyll in the samples, which indicates an increase of the thickness of the spongy layer and leaf blade due to the number of periclinal cell divisions and increase of the volume of intercellular spaces. The obtained data confirm the nonspecific reaction of the assimilation apparatus of birch trees on the influence of stress environmental factors. The ontogenetic reactions of indicators of the mesostructure of B. nana are considered as adaptive responses to technogenic stress, providing the decrease in transpiration and optimal photosynthesis under conditions of environmental pollution of the Arctic city. Dwarf birch can be used as an object for biomonitoring of environmental quality in the industrial areas of the Arctic and Subarctic.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Betula nana</kwd><kwd>мезофилл</kwd><kwd>онтогенез</kwd><kwd>техногенный стресс</kwd><kwd>Арктика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Betula nana L.</kwd><kwd>mesophyll</kwd><kwd>ontogeny</kwd><kwd>technogenic stress</kwd><kwd>Arctic</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abakumov E., Shamilishviliy G., Yurtaev A.
