Abstract:

Low temperature is a critical environmental factor constraining the stable and high yield of rice. Against the backdrop of climate variability, the threat of chilling injury to rice at various growth stages has become increasingly prominent. This paper systematically reviews the effects of low-temperature stress on rice growth and development, as well as its physiological and molecular mechanisms, covering key processes such as morphological damage, changes in membrane permeability, oxidative stress, photoinhibition, and energy metabolism imbalance. It summarizes the comprehensive response and adaptation mechanisms established by rice through antioxidant systems, heat shock proteins, osmotic regulators, hormone networks, and energy sensing systems (e.g., SnRK1/TOR). Furthermore, feasible techniques for enhancing rice cold tolerance in production are outlined, including optimizing sowing dates, cold acclimation, synergistic fertilizer-water management, exogenous regulators, and improved cultivation measures. Finally, key future research directions are proposed, emphasizing the need to construct regional chilling avoidance and mitigation systems through the deep integration of genetic improvement and cultivation regulation, thereby providing support for ensuring stable rice production and national food security.

Key words: rice, low temperature stress, cold tolerance mechanism, regulation strategies

摘要:

低温冷害是制约水稻稳产高产的重要环境因素,尤其在气候多变背景下其对水稻各生育阶段的威胁日益突出。本文系统综述了低温胁迫对水稻生长发育的影响及其生理与分子机制,涵盖低温导致的形态损伤、膜透性改变、氧化胁迫、光抑制及能量代谢失衡等关键过程;总结了水稻通过抗氧化系统、热激蛋白、渗透调节物质、激素网络及能量感应系统(如SnRK1/TOR)构建的综合响应与适应机制。在此基础上,梳理了生产中通过优化播期、抗寒锻炼、肥水协同管理、外源调节剂应用及栽培措施改良等提升水稻耐冷性的可行技术。最后,展望了水稻耐冷性研究的重点方向,强调通过遗传改良与栽培调控深度融合,构建区域性避寒抗寒技术体系,为保障水稻生产稳定和国家粮食安全提供支撑。
