The recent climate instability has led to an increase in the strength and frequency of environmental stressors affecting fruit plants. As a result, their physiological condition deteriorates, and their resistance to adverse biotic and abiotic factors decreases. The aim of the research was to determine the drought and heat resistance of varieties and hybrids of columnar apple trees in the Forest-Steppe region of Ukraine. During the studies, the overall condition of the plants was assessed, the dates of the onset of phenological phases were recorded, tissue hydration, water deficit, and water-holding capacity of the leaves were determined. Based on the observations, we conclude that all varieties and hybrids of columnar apple trees exhibit good to excellent overall condition, making them suitable for cultivation in this zone.
