摘要:

水稻种子的耐贮性是关系到粮食贮藏安全和用种安全的重要性状,也是目前从事种子科学研究的学者和种子企业重点关注的性状之一。耐贮性强的水稻种子经过长时间的贮藏仍然具有较高的种子活力,可以更好地解决粮食贮藏和用种安全问题。本综述介绍了种子贮藏过程中发生老化劣变的原因,论述了贮存期间种子内部的生理生化机制与分子损伤机制,归纳了水稻种子耐贮性遗传机理的研究进展,对如何选育耐贮性强的水稻新品种进行了展望。

Abstract:

The storability of rice seeds is an important trait related to grain storage safety and the safety of seed use, it is also the focus in seed research and by seed enterprises. Rice seeds with strong storability still exhibit high seed vigor after long-term storage, these rice varieties can be better used to solve the problem of grain storage and the safety of seed use. In this review, we introduced the reasons of seed aging and deterioration, discussed the physiological and biochemical mechanisms of seed during storage, summarized the research progresses of genetic mechanism of rice seed storability. Finally, we made an outlook for how to breed the new variety of rice with strong storability.

Key words: rice, seed, storability, genetic mechanism
