Abstract: Seed ultradry storage is recently a hot research spot in the fields of seed biology and plant germplasm resources preservation.Advances in seed ultradry storage research were reviewed in this paper,implicated in (1) changes in cellular and subcellular structure of ultradry seeds;(2)effects of ultradry treatment on water state of seeds,and the relationship between the changes in water state and reaction rate of seed deterioration;(3)free radical damage and accumulation of toxic products in ultradry seeds;(4)endogenous antioxidants in ultradry seeds,and (5) protective roles of sugar and amphiphilic molecules against extreme desiccation in seed cells.In addition,perspective of resaerch on seed ultradry storage has been made in this paper.
