ANALYSIS OF THE PHYSIOLOGICAL QUALITY OF SOYBEAN SEEDS SUBJECTED TO DIFFERENT ENVIRONMENTS

Authors

Abstract

Soybean (Glycinemax (L.) Merr) is a crop of global economic importance, widely used in food, feed and industrial products. Maintaining seed quality during storage is crucial, as biotic and abiotic factors can affect seed viability. The objective of this study was to analyze the physiological quality of soybean seeds stored under different environmental conditions. The experiment was conducted at the Seed Analysis Laboratory (LAS) using four cultivars (Neo710 IPRO, BRS 511, 80I82RSF IPRO and Neo 790 IPRO) stored in a controlled and uncontrolled environment. Five evaluations were carried out for each cultivar between March 2023 and February 2024, including germination, accelerated aging and tetrazolium tests. The collected data were subjected to analysis of variance and mean test (Scott-knott 5%). The results indicated that, in general, the storage environment did not significantly influence the physiological quality of the seeds throughout the evaluated period. However, in specific situations, controlled conditions proved to be beneficial, presenting better averages. Although short-term storage of 11 months under uncontrolled conditions did not cause significant changes in most tests, maintaining a controlled environment is recommended to preserve the physiological quality of soybean seeds in the long term.

Keywords: Glycine max L., germination, tetrazolium.
