Abstract

The examination of plant resistance to drought is becoming increasingly relevant due to global warming. All species of the genus Aristolochia L. possess high decorative qualities and play an important role in natural ecosystems. However, under conditions of temperature imbalance, their ornamental value may decrease due to leaf turgor loss and even leaf shedding. The purpose of the paper is to highlight the results of studies on the drought resistance assessment of Aristolochia L. plant species to identify the most promising taxa suitable for cultivation in the city of Kyiv. The study was conducted in 2022 on three species of vines: Aristolochia macrophylla Lam., A. tomentosa Sims., A. manshuriensis Kom., which grow in the M.M. Gryshko National Botanical Garden (Kyiv). The study presented results on leaf hydration parameters, water deficit, water-holding capacity of leaves, electrical conductivity, and specific leaf area conducted in the Plant Physiology and
