Effect of salinity on ecological and physiological characteristics of winter wheat varieties

Abstract

In connection with the influence of salt stress on winter wheat varieties in the soil and climatic conditions of the Bukhara oasis, it is of practical importance to determine the physiological foundations of the level of resistance and adaptation, as well as to determine resistance to stress and develop methods for increasing resistance. In studies to assess the effect of salt stress on wheat, physiological, biochemical, plasmolytic, morphological, biometric, statistical, comparative-analytical, phenological, and gasometric methods were used. In the ontogeny of winter wheat varieties, physiological methods have been developed for determining the degree of resistance to salt stress by determining the amount of bound water in the leaves (BWC), the level of cell turgor (TC), physiological methods for increasing resistance to salt stress by treating seeds before sowing.
