A Global Experiment to Explore Ultra Dry Seed Storage Technology and Optimum Condition for Seed Storage Perspectives after 14 Year uri icon


  • Ultradry seed storage might extend the viability of seeds conserved in genebanks without incurring the expense of refrigeration. It remains unclear whether drying seeds to very low water contents can achieve the same longevity as freezer storage. Also, excessive drying might hasten seed aging. The debate about ultradry storage is really a question about whether temperature and water content are interacting factors affecting seed aging rates.In 1994, Bioversity International (previously IPGRI) sponsored a global experiment with a complete factorial design to resolve the debate. This model approach for settling complex and controversial issues with global relevance will guide better storage practices for seed banks
