摘　　要：种子超干贮存即采取低含水量种子密闭贮藏在常温条件下的方法,以达到部分或全部取代低温库的目的。超干贮存能提高种子的耐藏稳定性,但并不是越低越好,蛋白质、抗氧化系统、糖、细胞膜系统都与种子的耐脱水性有关,种子超干贮存不仅要提高种子生活力还要保持种子的遗传稳定性。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.
