俄语. Проводящая система стебля пшеницы характеризуется высокой степенью упорядоченности, которая проявляется в однотипной конструкции проводящих пучков и их симметричном расположении в междоузлиях. Обнаружены нетипичные пучки с отклонениями в строении и топографии. Их встречаемость зависит от набора хромосом, генома, видовых особенностей растений и метамерной принадлежности изучаемого междоузлия. Анализ встречаемости таких пучков углубляет представления об анатомии растений и может быть использован в селекции пшеницы.

In a course of the research there were studied atypical vascular bundles of the stem in polyploid row of wheat (Triticum) and quantitative estimation of occurrence of atypical vascular bundles. The research was realized in the conditions of the Republic of Belarus. As a result of realized research there was revealed that conducting system of the stem of wheat was characterized by a high degree of order, which manifested itself in the structure of the same type of vascular bundles and their symmetrical arrangement in the interstices. Atypical bundles with deviations in the structure and topography were detected. Their occurrence depended on a set of chromosomes, genomes, species characteristics of plants and metameric character of the studied interstices. Analysis of the occurrence of such bundles deepened the understanding of the anatomy of plants and could be used in wheat breeding.
