Relationship Between Chemical Treatment of Soybean (Glycine max (L.) Merr.) Seeds and Synthesis of Antioxidant Enzymes

This research aimed to assess the relationship between chemical treatment with different combinations of products and the physiological quality of seeds stored for 0 and 180 days. The experimental design adopted was the completely randomized (CRD), with four replications. The treatments consisted of the "cultivar", "seed treatments" and "storage periods" factors. To characterize the quality of the seeds, lignin quantification analysis, peroxidase activity analysis, catalase activity analysis, and scanning electron microscopy (SEM) were carried out. The physiological quality of the seeds decreases as the storage period increases. The lignin present in the seed coat of cultivar TMG 7061 IPRO provided greater protection compared to cultivar 7067. The images referring to cultivar 7067 showed morphological changes resulting from damage caused by the treatment and storage of the seeds.
