| 温度影响烤烟生长发育，随着当前极端高温和低温灾害的频发，温度胁迫成为制约烤烟正常生长发育和生理功能的重要因素之一。低温胁迫和高温胁迫是目前烤烟苗期和成熟期中最常见的灾害，对烤烟品质和产量造成严重影响。综述了温度胁迫对烤烟生长发育、光合功能、碳氮代谢、抗氧化系统等生理过程的影响，介绍了植物蛋白和分子机制在温度胁迫方面的相关研究进展，系统总结了目前针对田间温度胁迫的抗逆调控措施，包括田间管理和喷施外源物质。目前针对温度胁迫管理的大多农艺干预措施尚不完善，需要深入了解不同品种的遗传、生化和生理过程，以鉴定和选择性状，并增强其耐高温机制，培育耐高温胁迫的烤烟品种。对今后研究进行展望，包括挖掘地方种质资源，培育耐热品种，利用多组学或交叉组学等手段深度挖掘烤烟温度胁迫响应机制，开展对烤烟温度胁迫的预测研究，有针对性制定抗逆栽培管理措施等，以期为烤烟防御气候灾害和农业减灾增效提供科学支持。 |

| Temperature affects the growth and development of tobacco. With the frequent occurrence of extreme high and low temperature disasters, temperature stress has become one of the important factors restricting the normal growth and physiological functions of flue-cured tobacco. Low temperature stress and high temperature stress are currently the most common disasters in the seedling and maturity stages of flue-cured tobacco, which have a serious impact on the quality and yield of flue-cured tobacco. This article reviews the effects of temperature stress on physiological mechanisms such as growth and development, photosynthetic function, carbon and nitrogen metabolism, and antioxidant system of flue-cured tobacco. It introduced the research progress of related plant proteins and molecular mechanisms in temperature stress, and systematically summarizes the current stress resistance control measures for field temperature stress, including field management and spraying exogenous substances. At present, most agronomic interventions for temperature stress management may not be complete. It is necessary to understand the genetic, biochemical and physiological processes of different varieties in order to identify and select traits, enhance their high-temperature resistance mechanism, and cultivate high-temperature resistant flue-cured tobacco varieties. Looking forward to future research on temperature stress in flue-cured tobacco, including exploring local germplasm resources, cultivating heat-resistant varieties, utilizing methods such as multi omics or cross omics to deeply explore the response mechanism of temperature stress in flue-cured tobacco, developing predictive research on temperature stress in flue-cured tobacco, and developing targeted management measures for stress resistance cultivation, in order to provide scientific support for the prevention of climate disasters and the enhancement of agricultural disaster reduction efficiency for flue-cured tobacco. |
