Aim. To analyze the experience of Ukrainian and foreign scientists on technologies to increase the adaptive potential of cultivated in vitro plants to ex vitro conditions. Results. Modern acclimatization technologies are mainly aimed at improving the methods of adaptation of planting material of in vitro collections to ex vitro conditions. Much less attention is paid to technologies to increase plant resilience at the stage of their multiplication and growth in vitro. Integration and systematization of research results of a large number of scientists is allowed to describe the main strategies and methodological techniques, which implementation can significantly increase the adaptive potential of in vitro plants. Conclusions. Optimization of physical and chemical conditions of plant cultivation in vitro can induce changes in their phenotype, intensity of photosynthetic reactions, water balance, which increases the adaptive potential of plants and facilitates the process of their acclimatization to ex vitro conditions.

Key words: in vitro plants, acclimatization to ex vitro conditions, adaptive potential, technology.
