Parameters of chlorophyll photoactivity were studied using the fluorimeter “Florоtest” to identify сhаenomeles genotypes with high drought tolerance. The studied genotypes were characterized by a rapid loss of water during withering (28.4-63.9 % within 4 hours) and a significant restoration of leaves turgor (58.3-93.8 %) under favorable conditions. The development of water stress was accompanied by varying degrees of decrease in the photoactivity of genotypes leaves. On average, the Stats-dama v
