摘　　要：低温冷害影响水稻生理功能变化,如光合作用、呼吸作用、矿质养分吸收、膜脂过氧化以及抗氧化系统。本研究一方面详细介绍了低温胁迫下,光合作用、呼吸作用、矿质养分吸收、膜脂过氧化以及抗氧化系统变化机制,着重分析了低温胁迫下,水稻体内脱水蛋白、酶蛋白、活性氧、内源激素以及细胞膜脂肪酸组分的变化相关生理机制;另一方面,从冷害调控角度出发,较全面地综述了外源植物生长调节剂在水稻冷害调控方面研究概况,提出中国在水稻冷害研究领域的未来发展方向与新趋势,进而为今后水稻冷害相关研究提供理论依据。Chilling damage affects the change of rice physiological functions, such as photosynthesis,respiration, mineral nutrition uptake, membrane lipid peroxidation and antioxidant system. On the one hand,we introduced the change mechanism of photosynthesis, respiration, mineral nutrition uptake, membrane lipid peroxidation and antioxidant system under low temperature stress, particularly, the physiological mechanism of dehydrin, apoenzyme, active oxygen, endogenous hormones and the fatty acid component of the cell membrane under low temperature stress; on the other hand, from the perspective of chilling damage regulation, we summarized recent research progress on the exogenous plant growth regulator in regulating rice chilling damage, discussed the development direction and new trend in the research field of rice chilling damage, and provided a theoretical basis for future rice chilling damage research.
