В настоящее время использование междисциплинарного подхода, основанного на сочетании традиционных интродукционных методов и приемах клонального микроразмножения, позволяет решить одну из ключевых задач интродукции по созданию биоресурсных коллекций, состоящих из отборных экземпляров растений с ценными хозяйственными признаками, устойчивых к неблагоприятным условиям городской среды. Материалы и методы. Проведенное интродукционное исследование выявило семь экземпляров Malus niedzwetzkyana Dieck, устойчивых к урбанизированным условиям, с высокими показателями развития кроны и долговечности. Данные растения послужили исходным материалом для разработки протокола клонального микроразмножения и сохранения in vitro отборных форм этого вида. Результаты. Установлено, что у M. niedzwetzkyana наиболее благоприятный срок взятия растительного материала для введения в культуру in vitro – начало периода активного роста вегетативных побегов после цветения. Самый оптимальный способ стерилизации растительного материала – ступенчатый режим с использованием спирта, гипохлорита натрия и нитрата серебра, позволяющий получить от 50 до 70% стерильных эксплантов и максимальный процент пролиферации меристем. На этапе микроклонального размножения сочетание 0,8 мг/л бензоаминапурина (БАП) с 0,14 мг/л индолил-3-масляной кислоты (ИМК) позволило существенно повысить коэффициент размножения (в среднем до 5,3 ± 0,7) и улучшить морфометрические показатели микропобегов; максимальная частота пролиферации побегов составила 100%. Выход адаптированных к условиям ex vitro побегов составил 90%.Заключение. Разработанный протокол клонального микроразмножения позволил ввести в культуру in vitro и размножить отборные формы M. niedzwetzkyana с целью создания ресурсной базы родового комплекса Malus Mill. для дальнейших фундаментальных и прикладных исследований.</p></abstract><trans-abstract xml:lang="en"><p>Background. Currently, the use of an interdisciplinary approach based on a combination of traditional introduction methods and clonal micropropagation techniques makes it possible to solve one of the key problems of introduction – the establishment of bioresource collections consisting of selected plant accessions with valuable agronomic traits and resistance to unfavorable urban environments. Materials and methods. A plant introduction study resulted in identifying seven specimens of Malus niedzwetzkyana Dieck with resilience to urban environments, high rate of crown development, and longevity. They served as source material for the development of a clonal propagation protocol and in vitro preservation of selected genotypes of this species. Results. It was shown for M. niedzwetzkyana that the most favorable time for taking its plant material for introduction into in vitro culture is the beginning of the active growth of vegetative shoots after flowering. The most optimal sterilization technique for such plant material was a stepwise regime using alcohol, sodium hypochlorite, and silver nitrate: it provided from 50 to 70% of sterile explants and the maximum percentage of meristem proliferation. Combining 0.8 mg/L of benzylaminopurine (BAP) with 0.14 mg/L of indole-3-butyric acid (IBA) at the stage of microclonal propagation ensured a significant increase of the reproduction coefficient (on average up to 5.3 ± 0.7) and an improvement in morphometric parameters of microshoots; the maximum frequency of shoot proliferation was 100%. The yield of shoots adapted to ex vitro conditions was 90%. Conclusion. The developed clonal micropropagation protocol made it possible to introduce selected M. niedzwetzkyana forms into in vitro culture and reproduce them in order to set up a resource base for further fundamental and applied research into the system of the genus Malus Mill.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Malus Mill.</kwd><kwd>размножение in vitro</kwd><kwd>пазушные меристемы</kwd><kwd>интродукция</kwd><kwd>городское озеленение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Malus Mill.</kwd><kwd>in vitro propagation</kwd><kwd>axillary meristems</kwd><kwd>introduction</kwd><kwd>urban gardening</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках государственного задания согласно проектам АААА-А21-121011290027-6 и AAAAA21-121011290025-2.</funding-statement><funding-statement xml:lang="en">the study was performed within the framework of the state task under Projects АААА-А21-121011290027-6 and AAAAA21-121011290025-2.</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">Барсукова О.Н.
