“…A higher relation with drought resistance was found in the water loss (WL), which correlated (r = 0.97-1.00) with the leaf-area damage after dehydration (S24 and S48). The criterion's effectiveness is confirmed by other numerous studies on peach and other plants of the genus Prunus [110,[112][113][114]. The assessment of water regime indicators is fast and quite objective but, however, not always suitable given the destructive nature of this method.…”

The article presents an analysis of the artificial dehydration effect of peach leaf tissues, simulating natural drought, on various physiological, morphological, and anatomical parameters described in the literature, associated with the trait of drought resistance. An investigation aimed to identify the most informative criteria for peach drought resistance which correlate with water loss during dehydration. The results present an assessment of the amount of water loss in 60 peach cultivars selected from different geographical areas and having different genetic origins. Four contrasting genotypes were identified, based on the results of the cluster analysis performed on the cultivar’s water regime. The influence of water regime parameters (leaf water content, water saturation deficit, dynamic of water loss), the morphological and anatomical structure of the leaf, the content of photosynthetic pigments, and the activity of the photosynthetic apparatus on drought resistance were investigated for selected peach cultivars. It was revealed that the most informative criteria for assessing drought resistance were dry and fresh leaf weight, leaf blade length, leaf width, and area (among morphometric parameters); stomatal pore length, stomata density, adaxial and abaxial epidermis thickness, and adaxial cuticle thickness (among anatomical parameters); and Fv/Fm—maximum photochemical quantum yield of PSII, Y(NO)—quantum yield of unregulated non-photochemical light energy dissipation in PS II and Y(NPQ)—controlled quantum losses (among indicators of photosynthetic activity).

The results of the study of drought resistance of 4 cultivars Prunus armeniaca Lam bred in the Nikitsky Botanical Gardens are presented. The dynamics of indicators of the water regime of leaves, the content of photosynthetic pigments and phenolic compounds in them has been studied. As a result of the research, information was obtained on the physiological and biochemical characteristics of apricot against the background of adaptation to stressful conditions created by moisture deficit during the summer drought on the Southern Coast of the Crimea. Significant differences were revealed in the ability to retain moisture during wilting, the ability to restore tissue turgor after critical dehydration, the concentration of chlorophylls and phenolic substances in the cultivars of different resistance to water stress. The promising drought-resistant genotypes 'Professor Smykov' and 'Kazachok' have been identified, demonstrating a relatively high level of water-retaining forces of leaf tissues and reparation of the leaf surface area.
