Objective: The objective of this study was to observe the morphological and biochemical changes of salicylic acid in soybean grown under salinity stress. Material and Methods: The study was carried out in climate room of Van Yuzuncu Yil University, Faculty of Agriculture, Department of Field Crops in 2019. The “Ilksoy” soybean variety was used in the study. Four different salisilic acid doses (0, 0.5, 1 and 1.5 mM) and 3 different NaCl salt doses (0, 150 and 300 mM) were applied. Plant releated properties such as root - stem length, root -stem fresh weight, root - stem dry weight, leaf area, chlorophyll content, ion leakage in leaf tissues (ILLT), lipid peroxidation level (MDA), relative water content (RWC) and membrane resistance in leaf tissues (MRLT) were determined. Results and Conclusions:It was observed that as the salt doses increased, the stem fresh weight of the soybean plants decreased, and the lowest value was obtained from 1.26 g and 300 mM salt concentration. The highest MDA content (0.75 nmolg-1 FW) and the lowest chlorophyll content (39.46 SPAD) were obtained when the 300 mM NaCl dose was applied. From the study conducted, the stem length, root, stem fresh and dry weights, RWC, MRLT, leaf area and chlorophyll ratio decreased with salt stress applications while the MDA and ILLT values increased. In addition, the longest roots were detected in 150 mM salt applications as compared to the control.
