The purpose of the study was to establish the optimal type of cuttings for the technology of root propagation of Viburnum opulus. The cuttings were harvested from native Viburnum opulus mother plants under the conditions of the nebulizing installation of the winter garden of the Podillia botanical garden of the Vinnytsia National Agrarian University. According to the research results, it was established that the rooting and further development of rooted green Viburnum opulus cuttings of the Velikoplidna variety depends on the type of cutting. Analyzing the influence of the type of cutting on the rooting of cuttings of the Velikoplidna variety in the investigated time of cutting, it should be noted the high rooting of cuttings in the variant with three nodes. A gradual decrease in the number of nodes led to a significant decrease in the rooting of green cuttings. Green cuttings of the Velikoplidna variety harvested during the period of mass flowering from the basal part of the shoot with three nodes were characterized by significantly higher rooting, number and length of the root system compared to cuttings harvested from the medial and apical parts. Green cuttings of the Velikoplidna variety harvested during the period of intensive growth of shoots from the medial part of the shoot with three nodes were characterized by significantly higher rooting, number and length of the root system compared to cuttings harvested from the basal and apical parts. Green cuttings of the Velikoplidna variety harvested during the period of slow growth of shoots from the apical part of the shoot with three nodes were characterized by significantly higher rooting, number and length of the root system compared to cuttings harvested from the basal and medial parts.
