Global climate change has increased the severity and frequency of abiotic stresses, posing significant challenges to the survival and growth of woody plants. Non-structural carbohydrates (NSCs), including starch and sugars, play a vital role in enabling plants to withstand these stresses, helping to stabilize cellular functions by buffering plant energy demands and facilitating recovery on the alleviation of stress. Despite the recognized multiple functions of NSCs, the contrasting effects of multiple abiotic stresses on NSCs dynamics in woody plants remain poorly understood. This review aims to explore the current knowledge of the contrasting effects of abiotic stress conditions including drought, salinity, heat, water logging, and cold on NSCs dynamics. The roles of NSCs in regulating stress-resilience responses in woody plants are also discussed, along with the challenges in NSC measurement, and options for future research directions are explored. This review is based on comprehensive literature research across different search engines like Scopus, Web of Science, and Google Scholar (2000-2024) using targeted keywords. This study compiles the current research on NSCs functions and provides insights into the adaptive strategies of woody plants in response to changing climate conditions, providing groundwork for future research to improve stress tolerance in woody plants.
全球气候变化加剧了非生物胁迫的严重程度和发生频率，给木本植物的生存和生长带来了重大挑战。包括淀粉和糖类在内的非结构性碳水化合物（NSCs）在使植物能够抵御这些胁迫方面发挥着至关重要的作用，通过缓冲植物的能量需求来帮助稳定细胞功能，并在胁迫缓解时促进恢复。尽管NSCs具有多种公认的功能，但多种非生物胁迫对木本植物NSCs动态的对比效应仍知之甚少。本综述旨在探讨干旱、盐度、高温、水涝和寒冷等非生物胁迫条件对NSCs动态的对比效应的现有知识。还讨论了NSCs在调节木本植物胁迫恢复反应中的作用，以及NSC测量中的挑战，并探索了未来研究方向的选择。本综述基于使用目标关键词在Scopus、Web of Science和Google Scholar等不同搜索引擎上进行的全面文献研究（2000 - 2024年）。本研究汇编了关于NSCs功能的当前研究，并深入了解木本植物应对气候变化条件的适应性策略，为未来提高木本植物胁迫耐受性的研究奠定基础。
