Исследование проводилось методом выращивания растений в полужидком (0,7%) голодном агаре, инокулированном указанными штаммами бактерий. Показано, что данные микроорганизмы могут приживаться и развиваться в ризосфере за счет корневых экссудатов, что подтверждает их фитопротекторные и ростстимулирующие свойства. Авторы анализируют влияние факторов окружающей среды на процесс колонизации, а также оценивают степень влияния исследуемых бактерий на полезную почвенную микрофлору. Выявлено, что внесенные микроорганизмы не оказывают ингибирующего воздействия на основные эколого-трофические группы микробиоты, участвующей в обеспечении плодородия почвы. Установлено, что процесс колонизации зависит от ряда факторов, включая состав корневых выделений, способность бактерий к адгезии, скорость их размножения и выживаемость в ризосфере. Метод оценки колонизирующей способности, основанный на выращивании растений в полужидком голодном агаре, показал свою эффективность и позволяет проводить быструю первичную диагностику перспективных штаммов ризобактерий. Экспериментально доказано, что в присутствии корневых экссудатов Agrobacterium tumefaciens 184 и Streptomyces sp. 3 активно образуют микроколонии на корневой поверхности сахарной свеклы, начиная со 2–5 суток после инокуляции. Развитие бактериальных колоний усиливается к 14-м суткам, при этом наибольшая плотность наблюдается в области корневой верхушки. Полученные результаты подчеркивают перспективность использования данных штаммов в агротехнологиях, направленных на повышение устойчивости сахарной свеклы к фитопатогенам и улучшение ее роста. Важным выводом является отсутствие негативного воздействия ризобактерий на естественную микрофлору почвы, что подтверждает возможность их применения в качестве биопрепаратов в сельском хозяйстве.</p></abstract><trans-abstract xml:lang="en"><p>The article discusses the ability of the rhizobacteria Agrobacterium tumefaciens 184 and Streptomyces sp. 3 Colonize the root system of sugar beet. The study was conducted by growing plants in semi-liquid (0.7%) starved agar inoculated with these bacterial strains. It has been shown that these microorganisms can take root and develop in the rhizosphere due to root exudates, which confirms their phytoprotective and growth-stimulating properties. The authors analyze the influence of environmental factors on the colonization process, as well as assess the degree of influence of the studied bacteria on the beneficial soil microflora. It was revealed that the introduced microorganisms do not have an inhibitory effect on the main ecological and trophic groups of the microbiota involved in ensuring soil fertility. It has been established that the colonization process depends on a number of factors, including the composition of root secretions, the ability of bacteria to adhere, the rate of their reproduction and survival in the rhizosphere. The method of assessing the colonizing ability, based on growing plants in semi-liquid starved agar, has shown its effectiveness and allows for rapid primary diagnosis of promising strains of rhizobacteria. It has been experimentally proven that in the presence of root exudates of Agrobacterium tumefaciens 184 and Streptomyces sp. 3 actively form microcolonies on the root surface of sugar beet, starting from 2-5 days after inoculation. The development of bacterial colonies increases by the 14th day, with the highest density observed in the area of the root apex. The results obtained emphasize the prospects of using these strains in agricultural technologies aimed at increasing the resistance of sugar beet to phytopathogens and improving its growth. An important conclusion is the absence of negative effects of rhizobacteria on the natural microflora of the soil, which confirms the possibility of their use as biological products in agriculture.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ризобактерии</kwd><kwd>сахарная свекла</kwd><kwd>колонизирующая способность</kwd><kwd>Agrobacterium tumefaciens 184</kwd><kwd>Streptomyces sp. 3</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rhizobacteria</kwd><kwd>sugar beet</kwd><kwd>colonizing ability</kwd><kwd>Agrobacterium tumefaciens 184</kwd><kwd>Streptomyces sp. 3</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">Нетрусов, А.
