Abstract: The article uses various diagnostic methods to investigate the salt and drought resistance of five strawberry genotypes (Reddekut, Carmen, Fakhraly F/14, Barda B/13, XQI 1/18).The water-holding capacity, one of the diagnostic indicators of resistance, in the studied samples ranges from 66% to 57%, whereas the total water content in the leaves varies from 77% to 71%.Based on the results obtained, the genotypes of the strawberry varieties Reddekut and Carmen, which exhibit lower water loss, can be classified as resistant.Another diagnostic method involves assessing the resistance of plants to stress factors by measuring changes in the amount of chlorophyll (a + b) under their influence.The Reddekut variety and the strawberry form XQI/18 demonstrated an increase in chlorophyll content under drought conditions by 8.16% and under salinity by 18.21%.According to the research results, these strawberry samples can be considered highly resistant to both salinity and drought.It was determined that exposure to stress factors disrupts metabolic processes, resulting in the accumulation of proline and various other amino acids without being consumed, thereby increasing their levels compared to the control.Consequently, the amino acid proline is utilized as a biochemical marker of resistance.In our study, following exposure to stress factors, the amount of the amino acid proline increased in all strawberry varieties and forms.However, in one form (Fakhraly F/14), a decrease in this indicator was observed compared to the control under drought conditions.This fact can be associated with the consumption of the proline reserves that the plant utilizes when resisting stress.
