The results of the introduction into the climatic conditions of southern taiga of 203 species of herbaceous plants were analyzed. There was made evaluation of the statistical significance of the influence of the geographical distribution of species on prospectivity of their introduction and on its component indicators. The species with areals covering the natural zone, in which point of introduction is located, showed the best result, but only the differences between subtropical and tropical species, on the one hand, and the remaining groups of species, on the other hand, were statistically significant. Seed reproduction, winter hardiness, the duration of existence of the species in the new environment are most highly dependent on the specificity of latitudinal and longitudinal spread. The size of the areal is not of great significance in cases where the areal of the species includes natural zone in which the introduction point is located. The intensification of the degree of continentality of the climate in the homeland of the species studied led to a significant decrease in the intensity of vegetative propagation and the increase in plant size under the conditions of introduction.Key words: introduction of plants, prospectivity of introduction, geographical distribution of plants.
