Abstract: Germination inhibitors substances that prevent the germination of seeds, spores, and other plant reproductive structures are widespread across the plant kingdom. These include compounds such as phenols, cyanides, alkaloids, essential oils, and amino acids. Based on their effects, these inhibitors can be categorized into germination destructors and germination retarders. Germination destructors damage the seed’s morphology, structure, or physiological function, while germination retarders are more closely associated with seed dormancy. When applied at appropriate dosages, exogenous retarders can artificially extend the dormancy period of non-dormant or short-lived seeds, offering valuable potential for post-harvest preservation and long-term germplasm storage. In contrast, germination destructors highly effective but non-selective compounds have promising applications in the development of eco-friendly herbicides. Current research on germination inhibitors faces challenges, such as identifying specific endogenous inhibitory substances, determining the minimum concentration required to induce dormancy, and assessing whether exogenous applications cause physiological damage to seeds. Future research should focus on identifying and tracking germination inhibitors, elucidating their mechanisms of action at both the biochemical and molecular levels, and exploring innovative applications for both destructors and retarders.
