Abstract
The relationship between the seasonal development features of 213 plant species introduced into the conditions of the southern taiga and the results of their introduction was studied. With the increase of the duration of vegetational period the success of the introduction оf species was statistically significantly rised. Spring-summerautumn-winter-green species were the most promising: in these species the more intensive seed and vegetative reproduction and increased duration of flowering were observed. The prospectivity of introduction of species with early start of growing season (in the second and third decades of April), flowering (in May) and with long fl owering (more than two months) was the highest. In species from another regions the regrowth of plants, fl owering and seed ripening were beginning significantly later than in species of local flora. In species growing in nature in more severe climatic conditions, these phenophases under conditions of introduction were beginning earlier.
