Maize, a major staple cereal crop in global food supply, is a thermophilic and short-day C4 plant sensitive to low-temperature stress. A low temperature is among the most severe agro-meteorological hazards in maize-growing areas. This review covers the latest research and progress in the field of chilling tolerance in maize in the last 40 years. It mainly focuses on how low-temperature stress affects the maize membrane and antioxidant systems, photosynthetic physiology, osmoregulatory substances and hormone levels. In addition, the research progress in identifying cold-tolerance QTLs (quantitative trait loci) and genes to genetically improve maize chilling toleranceis comprehensively discussed. Based on previous research, this reviewprovides anoutlook on potential future research directions and offers a reference for researchers in the maize cold-tolerance-related field.
玉米是全球粮食供应中的主要主食谷类作物，是一种喜温、短日照的C4植物，对低温胁迫敏感。低温是玉米种植区最严重的农业气象灾害之一。本文综述了过去40年玉米耐冷性领域的最新研究和进展。它主要关注低温胁迫如何影响玉米的膜系统和抗氧化系统、光合生理、渗透调节物质和激素水平。此外，还全面讨论了在鉴定耐寒QTL（数量性状位点）和基因以通过基因手段提高玉米耐冷性方面的研究进展。基于以往的研究，本文对未来潜在的研究方向进行了展望，并为玉米耐冷性相关领域的研究人员提供参考。
