| Shrnutí: | Peach is notable for its drought resistance as well as sensibility to moisture conditions. Therefore, improvement of breeding material and development of drought-resistant varieties can be numbered among our most pressing tasks. The object of research was 39 peach hybrid forms developed at Nikitsky Botanical Gardens. Throughout the research period the total water content in the leaves of hybrid forms amounted to 50.2-58.9%. The water deficit in leaves ranged from 11.2 to 25.9%. In the process of wilting the leaves of peach hybrid forms lost 26.4-39.8% of moisture content within 24 hours. High regeneration capacity of leaf surface (up to 86.2%) was observed in 3 early and 5 midripening forms. This research allowed us to identify hybrid forms with high drought tolerance, including 5 early-, 4 mid- and 1 late-ripening forms. |
