Summary: After analyzing data from the literature sources, it was found that R. viscosa, which ranks second after R. pseudoacacia in terms of the introduction process involvement, is characterized by less winter hardiness. According to Kachalov A.A. [10], R. viscosa proved its winter-hardiness in conditions of the east, northern and middle parts of Ukraine and Transcarpathia. In Vinnytsia conditions, it withstands frosts up to -30˚С. In Moldova (Chisinau R. pseudoacacia tolerates winter well and bears fruit. As a result of the research, it was established that winter hardiness of the genus Robinia L. species in conditions of introduction was 1-2 (3) points. The introduced genus Robinia L. species and forms, which were objects of the research, in conditions of Vinnytsia were able to withstand negative temperatures (up to -32˚C) without significant damage. According to the obtained data, it was established that the genus Robinia L. representatives belong to the droughtresistant species and are able to withstand a long period of dry and rainless weather. The level of drought resistance of the studied species and forms according to the Pyatnytskyi S.S. scale equals to 4-5 points. According to the Pyatnytskyi S.S. light-demanding scale, R. pseudoacacia belongs to the most photophilous tree species – heliophytes. It was also defined that such species as R. pseudoacacia, R. holdtii, R. ambigua are fully acclimatized, R. viscosa, R. luxurians are well acclimatized. Their acclimatization numbers are: R. pseudoacacia = 100, R. viscosa = 86, R. luxurians = 86, R. holdtii = 95, R. ambigua = 94. Having analyzed the studied species in terms of their decorative characteristics, it was found that the time of decorativeness in the genus Robinia L. species is divided into two periods: the first is the flowering one, and the second – the time of leaf pigmentation change. According to our observations, the studied representatives received 5 points of decorativeness according to the Kalinichenko O.A. method in the following time periods: 1) from 05.15.2022 to 06.15.2022 – the time of flowering; 2) from 18.08.2022 to 20.09.2022 – leaf colour change.
