В ходе проведенной комплексной оценки установлено, что инвазионный потенциал чужеродных видов более чем в 1,6 раза превышает значения, полученные для аборигенного вида. При исследовании аллелопатических свойств растений показано, что наибольшее ингибирующее влияние на линейные размеры как корней, так и побегов тест-культур оказывали 10 %-ные экстракты, полученные из надземной биомассы Н. мелкоцветковой. Меньшей степенью воздействия характеризовались экстракты из Н. обыкновенной и Н. железконосной соответственно. В условиях эксперимента продемонстрирован более высокий ингибирующий эффект действия экстрактов на рост корней тест-культур по сравнению с побегами.</p></abstract><trans-abstract xml:lang="en"><p>An analysis of the biological characteristics and invasive potential of alien species of Impatiens, which have been widely distributed throughout the Republic of Belarus and neighboring countries, was conducted. A comprehensive assessment has demonstrated that the invasive potential of the alien species of I. parviflora DC. and I. glandulifera Royle exceeds that of the native species of I. noli-tangere L. by more than 1.6 times. A study of the allelopathic properties of these plants revealed that 10 % extracts obtained from the above-ground biomass of I. parviflora exhibited the most significant inhibitory effect on the linear dimensions of both the roots and shoots of the test cultures. In contrast, extracts from I. noli-tangere and I. glandulifera exhibited a comparatively diminished effect. In experimental conditions, extracts demonstrated a greater inhibitory effect on test culture root growth compared to shoot growth.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инвазивный вид</kwd><kwd>аборигенный вид</kwd><kwd>недотрога мелкоцветковая</kwd><kwd>недотрога железконосная</kwd><kwd>недотрога обыкновенная</kwd><kwd>аллелопатическая активность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>invasive species</kwd><kwd>native species</kwd><kwd>impatiens parviflora</kwd><kwd>impatiens ironiferosa</kwd><kwd>impatiens vulgaris</kwd><kwd>allelopathic</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">Chen, Y.
