Abstract
Plants grown in saline soils endure salinity stress, which causes different response reactions, exhibit plant growth and yield production decreasing. This research aimed to study the effect of salinization (NaCl) on physiological and biochemical parameters of aboveground and underground organs of soybean (Glycine Max L.) plants. The following parameters were analyzed: growth parameters (shoot and root length and biomass accommodation), leaf area, root volume, relative water content, proline, photosynthetic pigments contents, and superoxide dismutase activity. Soybean plants were grown for 14 days in hydroponics with addition NaCl in concentrations of 0.1%, 0.2%, and 0.3%. During the study, NaCl-affected seedlings were compared with the control (without stress) plants of the same varieties. Comparison results of analyzed parameters showed that varieties «Akku» and «Lastochka» were tolerant to salinity stress, and «Victory» and «Ivushka» were sensitive. The obtained data on the effect of salinity stress on physiological and biochemical parameters of different soybean varieties can be used as indicators of salt tolerance in the process of breeding salt-resistant varieties.
