Research progress on ultradry seed storage

Ultradry seed storage is a method in which low moisture seeds are storied in a closed container at room temperature and aim to replace partly or entirely the low temperature seed storage bank. Ultradry seed storage could improve the storage stability of seeds, but not the seed moisture content the lower the better. Protein, inoxidizable system, sugar and membrane system all affected desiccation tolerance of seeds. Ultradry seed storage not only improves seed viability but also keep seed genetic stability.
