Comparative analysis demonstrates a positive correlation between oligosaccharide ratios and longevity in desiccation-tolerant seeds, indicating a protective metabolic role.

Key Points

To examine the relationship between soluble neutral carbohydrate composition, desiccation tolerance, and storage longevity across diverse tree seeds and soybean.
Analyzed soluble neutral sugar profiles, specifically oligosaccharides, disaccharides, sucrose, raffinose, and stachyose, across mature seeds from 16 tree species and soybean.
Measured seed longevity by determining the storage duration required for germination to decline to 50% of baseline under 5°C and 80–91% relative humidity.
Desiccation-sensitive (recalcitrant) seeds possessed an oligosaccharide-to-total sugar mass ratio under 0.05 and lost 50% germination within a few days to 8.3 months.
Desiccation-tolerant (orthodox) seeds showed elevated oligosaccharide-to-total sugar ratios alongside lower disaccharide proportions, indicating active oligosaccharide synthesis.
Seed longevity demonstrated a significant positive correlation with the mass ratios of oligosaccharide to total sugar and oligosaccharide to disaccharide in desiccation-tolerant species.
