  Abstract
  One of the criteria determining the suitability of plants for landscaping is their ability to tolerate stress associated with insufficient moisture and high temperatures during the growing season without reducing decorative qualities. In this regard, the goal of this work was to define the influence of water regime on the functionality of apple tree genotypes from the genetic collection of Genetic Selection Center of Michurin Federal Research Center. Simulation of wilting, heat shock, and water content recovery of genotypes based on changes in leaf mass was carried out in laboratory conditions. Drought conditions were created in a Sanyo MLR-350 environmental test chamber with maintaining a constant level of illumination of about 9,000 lux. The studies were carried out in the summer period (July-August) in the conditions of prolonged (at least 2-3 weeks) lack of precipitation. Assessment of the water regime of apple tree genotypes selected by decorative qualities during laboratory simulation of drought conditions was carried out. We selected genotypes with maximum drought tolerance and with high potential for using for landscaping and selection: Uralskoye nalivnoye, 7-I-4, 7-I-13, 7-I-14, 7-I-22, 7-I-42, 7-I -43, 7-I-104, 7-I-108.
