Respiration and Physiological Characters of Soybean (Glycine max (L.) Merr) Seeds After Invigoration Treatment
Year: 2025
Type: article
Abstract: Degradation of seed quality occurs quickly, which makes it difficult to meet national soybean targets. This damage has the effect of making soybean seeds less viable. Invigoration is one of the methods used to improve seed viability. Two common methods of invigoration are osmoconditioning and matriconditioning. The primary objective of this research was to determine the most effective invigoration medium for enhancing the quality and viability of soybean seeds (Glycine max (L.) Merr) through invigoration techniques. Additionally, the study aimed to examine the correlation between the respiration rate and the physiological properties of the seeds. The research was conducted at PGRI University of Yogyakarta over a four-month period, from January to April 2022. The study utilized a completely randomized design (CRD) with five factors and three replications. Observed variables included water content (WC), seed germination (SG), vigor index (VI), and respiration rate (RR). The findings indicated no significant differences in WC across treatments, while SG and VI also showed no notable variation among treatments. Regression analysis revealed a positive correlation between RR and WC, while RR showed negative correlations with both SG and VI. These results suggest that respiration rate is a reliable indicator of seed viability, reflecting the metabolic activity of seeds during storage
