种子超干贮藏技术应用面临的问题和研究方向

种子超干贮藏技术对种质资源保存具有很大的应用前景，但鉴于目前的研究进展，其应用还存在诸多技术上的问题。本文对种子超干贮藏技术在种子库中应用所面临的挑战以及需要开展的研究内容进行了如下几个方面的讨论：种子贮藏安全含水量下限的多样性决定了超干技术应用的复杂性；超干贮藏含水量安全下限的确定尚未有可靠的方法；超干贮藏的种子吸胀前需要恰当的预处理以避免吸胀损伤；超干处理前外源抗氧剂预处理可能改善超干贮藏效果；无氧条件可能对超干贮藏具有增效作用；糖类物质以及两性物质对种子在超干处理及超干贮藏过程中的保护作用。

Challenges on the Application of Seed Ultradry Storage in Seed Banks

Although the technology of seed uhradry storage is promising in plant germplasm conservation, particularly in areas where the refrigerated facilities are not always possible, its application in seed banks still has many challenges. The paper discussed this issue and gave seme suggestions on what are the necessary researches in this field to improve its feasibility of application in seed banks.
