This study investigated the effects of salinity and K-humate concentrations on soybean germination. The findings contribute to our knowledge of soybean germination under salt stress and the potential use of potassium humate. The experiment was conducted in the laboratory of the Department of Field Crops at Adnan Menderes University, Turkey. Seeds were surface-sterilized and placed on filter paper in Petri dishes. Different concentrations of water (control), NaCl solution (3 dS m-1), and K-humate solution were added. The experiment followed a factorial design with two factors and four replications. K-humate had a positive impact on germination rate. Significant differences were observed among control, salinity, and salinity * K-humate applications. Salinity reduced germination percentage. K-humate mitigated the negative effects of salinity, improving germination. These findings suggest the potential use of K-humate to enhance seedling establishment and overall plant productivity in salinity-affected environments.

This study was carried out with the objective to evaluate the effects of different concentrations of L-Tryptophan and Melatonin pretreatment on germination behavior of onion, leek, black carrot, and radish seeds exposed to saline stress. Seeds of samples were soaked for 24 hours in distilled water, 50,100, 150 ppm L-tryptophan, and 1.5, 3, and 4.5 µM melatonin solutions at 20° C in darkness. Seeds were placed in Petri dishes and watered to moisten the filter paper with different concentrations of NaCl (0, 150, 300 or 450 mM). The experiment was planned in a completely randomized design with four replications. Maximum germination percentage, germination index, time to complete 50% germination and mean germination time was measured at the end of the study. The results indicated that the effect of pre-treatment was significant on all studied traits in all species except for mean germination time for black carrot seeds. In addition, all germination parameters of seeds were delayed and decreased by salinity increasing from 0 mM to 450 mM NaCl. Overall, all doses of melatonin increased the maximum germination ratio and germination index values slightly under 300 mM NaCl stress conditions. In general, results which obtained from all doses of melatonin were close to each other, whereas increasing doses of L-tryptophan caused a negative effect in some cases.
