| Abstract | The article highlights the results of research on the study of biological and ecological features of root propagation and cultivation of black chokeberry (Aronia melanocarpa (Michx.) Elliott) genotypes for use in landscaping of the Right-Bank Forest-Steppe of Ukraine. For the first time, a thorough analysis of the ecological and biological features of growth and development of seven varieties of chokeberry in terms of the beginning and passage of the main phenological phases under the conditions of introduction was carried out. The results of study of ecological and biological features of the regeneration capacity of green stem cuttings and optimisation of certain biological phases of root propagation of introduced varieties of chokeberry, which are promising for use in green construction of the Right-Bank Forest-Steppe of Ukraine, are presented. It has been proved that varieties of chokeberry are distinguished by decorative properties, ecological and biological features of growth and development of mother plants under new cultivation conditions are not sufficiently studied, including the most active periods of growth of vegetative and vegetative-generative shoots, which is the biological basis for their root propagation. It has been found that the regeneration capacity of black chokeberry stem cuttings depends on the varietal composition, the timing of harvesting cuttings and their planting for rooting, the type of cuttings and their metamerism. It has been proved that green stem cuttings of the studied varieties of chokeberry have a weak regeneration ability, which depends on the individual development of the shoot and its structural elements. The optimal time for harvesting shoots and planting green stem cuttings for rooting is the phase of their intensive growth – June 1–10. A significantly higher rooting yield was observed in three-node cuttings harvested from the basal part of the shoot. The formation of the root system largely depends on the physiological readiness of the cutting for root formation, i.e. on the part of the shoot and its metamerism. The application of the studied agrobiological measures allows to increase the regeneration capacity of green stem cuttings of the studied varieties of chokeberry, to reduce the cuttings' time by 10–15 days and to increase the seedling yield by 10–25 %. | ||
