摘要: 糖类在植物种子中的累积随种子的发育阶段和种子类型不同而不同,并与种子脱水耐性的变化相联系。许多正常性植物种子的发育伴随着某些糖的累积,这些糖的累积已被认为在种子脱水耐性获得中起重要作用。但糖对种子脱水耐性的影响不是单独的,而是与ABA和蛋白质等物质协同作用。种子脱水耐性不仅与糖的种类和含量有关,而且与种子所处的生理状态和发育进程有关。本文综述了种子脱水耐性与糖关系的研究进展。

Abstract: Accumulation of sugars in plant seeds varies with developmental stages and seed categories and relates to seed desiccation-tolerance. Some certain sugars accumulate following with deveiop-ment of many plant seeds, which is considered to play an import role in acquisition of desiccation-tolerance. But effects of sugars on seed desiccation-tolerance are not independent but interact-with those of ABA, proteins et al. The desiccation-tolerance is correlated to not only categories and content of sugars, but also to physiological status and developmental courses. The research advances on relationship between seed desiccation-tolerance and sugar is reviewed in this paper.

Key words: sugar, desiccation-tolerance, seed, seed category, developmental stages
