| description |
Although high-quality naturally refined oil is rich in unsaturated fatty acids that give it exceptional biological value and a distinctive role within human nutrition, precisely because of its chemical composition oilseed rape seeds have limited longevity. This study addresses the complex dynamics of oilseed rape seed deterioration, shedding light on the impact of accelerated and natural aging on lipid composition and subsequent effects on germination and early seedling growth. Seeds from four oilseed rape varieties underwent 72 hours of accelerated aging at 41 °C and 100% relative humidity. Gas chromatography was employed for fatty acid (FA) composition analysis after converting FAs into volatile methyl esters (FAME). Tocopherols were quantified using high-performance liquid chromatography with fluorescence detection. Results revealed high initial germination across all genotypes, with a notable decline after one year of storage. Double-stress conditions intensified this decline, emphasizing the vulnerability of seeds to elevated temperature and humidity. Genotypic differences in germination underscore distinct mechanisms for preserving vigour under stress. Both natural and accelerated aging induced a significant reduction in unsaturated fatty acids, notably oleic and eicosenoic acids. The study highlights the crucial role of tocopherols in mitigating oxidative stress and preserving seed quality during aging. Altered lipid composition emerged as a factor influencing seed viability and seedling morphology, particularly under short-term storage and deterioration conditions. The findings contribute to a deeper understanding of oilseed rape seed resilience and offer insights into potential strategies for enhancing seed storage and maintaining seed quality in the face of environmental stressors.
