Black chokeberry (Aronia melanocarpa) is a shrubby plant with a root system of 0.5 m in the soil. Its fruits are rich with antioxidant properties, making it a valuable plant in the pharmaceutical, food, and perfumery industries. The following study comprised the microclonal propagation of A. melanocarpa acclimatized under the conditions of Uzbekistan. The efficacy of its seed coat in sterilization and germination underwent evaluation, and the germination was higher (32%) in husked seeds. Based on the analysis of clone stages, the study determined that starting from Mk3, the length of microshoots (3.2 cm) and other quality indicators were ready for the rooting stage. During the rooting of A. melanocarpa, applying different concentrations of IBA (1, 3, 5, 7, and 10 mg/l) served for the evaluation. Based on the results, 7 mg/l IBA emerged as an optimal dose of IBA for root formation in A. melanocarpa. During the black chokeberry’s acclimatization, plant survival was 100% in a 3:1 peat-perlite substrate.
