Abstract
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.
