种子耐税水性的研究（综述）

ADVANCES IN STUDY ON DESICCATION TOLERANCE OF SEEDS

摘要:

种子耐脱水性是近年植物生理学中的一个研究热点。本文综述种子发育、热稳蛋白、糖的积累以及抗氧化系统等与耐脱水性的关系，同时针对顽拗性种子具有明显的对脱水的敏感性，介绍了提高种子耐脱水性的可能途径。

Abstract:

Seed development, heat stable proteins, the accumulation ofsugars， and antioxidative systems， which associate with seed desiccation lolerance，are reviewed The storage of recalcitrant seeds is difficult due to their sensitivity, to desiccation. The possible ways to increase desiccation tolerance for recalcitrant seeds are suggested．
