顽拗性种子脱水敏感性研究进展

植物种子的脱水敏感性研究对种质资源的引种栽培和迁地保护具有重要意义。本研究综合评述了不同植物种子，尤其是具有休眠特性的顽拗性种子的脱水敏感性，归纳了顽拗性种子脱水耐性的模型构建、生态适应性策略、贮藏条件、脱水敏感性的发生调控机制等，并对顽拗性种子未来的研究方向进行了展望,旨在为顽拗性种子的贮藏及物种生物多样性保护研究提供有价值的信息。

Research Progress on Desiccation-Sensitivity of Recalcitrant Seeds

The study on the sensitivity of plant seeds to dehydration is of great significance for the introduction,cultivation and the ex-situ conservation of germplasm resources.In this paper,the dehydration sensitivity of different plant seeds,especially the recalcitrant seeds with dormancy characteristics was reviewed.The research progress was summarized in dehydrating tolerance model construction,ecological adaptation strategy,storage conditions,and regulation mechanism of dehydration sensitivity of recalculated seeds.Meanwhile,the future developments on the research of recalcitrant seeds were prospected to provide valuable information for the storage of recalcitrant seeds and the biodiversity conservation of species.
