Abstract

Long-term storage of crop seeds is critical for the conservation of germplasm resources, ensuring food supply, and supporting sustainable production. Rice, as a major food staple, has a substantial stock for consumption and production worldwide. However, its food value and seed viability tend to decline during storage. Understanding the physiological responses and molecular mechanisms of aging tolerance forms the basis for enhancing seed storability in rice. This review outlines the latest progress in influential factors, evaluation methods, and identification indices of seed storability. It also discusses the physiological consequences, molecular mechanisms, and strategies for breeding aging-tolerant rice in detail. Finally, it highlights challenges in seed storability research that require future attention. This review offers a theoretical foundation and research direction for uncovering the mechanisms behind seed storability and breeding aging-tolerant rice.

水稻的种子贮藏性：生理基础、分子机制及育种应用

作物种子的长期贮藏对于种质资源保护、粮食供应和可持续生产至关重要。作为一种主要粮食，水稻在世界范围内的生产和消费存量巨大，但在贮藏过程中却很容易失去食用价值和种子活力。因此，了解耐老化的生理反应和分子机制为提高水稻种子的贮藏性奠定了基础。本综述阐述了目前在种子贮藏性的影响因素、评估方法和鉴定指标方面取得的进展。它还详细讨论了耐老化水稻的生理后果、分子机制和育种方法。最后，它指出了种子耐藏性研究中需要应对的一些挑战。本综述为揭示种子贮藏性的内在机制和培育耐老化水稻提供了理论依据和研究方向。
