Salt stress impedes normal development, compromises plant quality, and reduces crop yield. The germination phase in soybean marks the initial stage of its growth cycle. Characterizing salt tolerance during this period can help stimulate natural environments aid rapid screening salt-tolerant varieties. Our study characterized 36 germplasms culture dishes period. Soybeans were subjected to varying concentrations (0, 60, 120, 180 mmol/L) NaCl solution simulate diverse levels stress, parameters such as energy, rate, root length measured. Statistical techniques analysis variance, membership function, cluster analysis, quadratic regression equations used, these was determined. critical indicators most effective concentration for assessing identified. tolerated low concentrations; however, greater than 120 mmol/L significantly inhibited indicators. vigor, vitality index, seed total fresh weight, dry weight could be used identify tolerance. semi-lethal 155.4 mmol/L, coefficient variation 20.00%, indicating that it a evaluating germination. A varieties classified into four through analysis.
