Abstract

Soybean (Glycin max L.) is one of the most important oily seeds in the world. This plant is rich in protein and unsaturated fats, and plays a significant role in human health with PHENOLIC COMPOUNDS and flavonoids. Indole Butyric Acid (IBA) is a plant growth regulator that plays a key role in producing PHENOLIC COMPOUNDS and increasing the antioxidant capacity of the plant. Thiamine is one of the important vitamins in strengthening the immune system and increasing the resistance to environmental stresses in the plant's growth stages. Regarding the effect of hormone AUXIN and thiamine on the production of PHENOLIC COMPOUNDS as one of the antioxidant compounds in growth stages, the aim of this study was to investigate the effect of the two compounds in two stages of soybean growth and compare their effect on PHENOLIC COMPOUNDS changes in order to Detecting higher antioxidant capacity in environmental stress tolerance. For this purpose, the DPX cultivar of soybean seeds were prepared from Dezful Agriculture Research Center and planted in perlite containing flowers. The plants were planted under factorial design under IBA treatments with three concentrations of 0, 10 and 50 and thiamine with three concentrations of 0, 50 and 200. Extraction and evaluation of PHENOLIC COMPOUNDS, anthocyanins and pigments in leaves were performed. Data were analyzed using Duncan's test at a significant level of 5%. The results showed that the combined use of AUXIN and thiamine increased the carotenoid content in both phases and caused a significant increase in phenolic content. Application of AUXIN alone reduced AUXIN and thiamine the anthocyanin content significantly in both phases, but did not have a significant effect on phenolic content. The results showed that the PAL ACTIVITY of the phenolic and anthocyanin content increased significantly in the 9- leaf stage compared to 3-leaf. Generally, the results showed that interaction effect between AUXIN and thiamine on PHENOLIC COMPOUNDS in different stages of vegetative growth significantly improved and increased plant defense.
