Quinoa ( Willd.) is a genetically diverse Andean crop that has earned special attention worldwide due to its nutritional and health benefits and its ability to adapt to contrasting environments, including nutrient-poor and saline soils and drought stressed marginal agroecosystems. Drought and salinity are the abiotic stresses most studied in quinoa; however, studies of other important stress factors, such as heat, cold, heavy metals, and UV-B light irradiance, are severely limited. In the last few decades, the incidence of abiotic stress has been accentuated by the increase in unpredictable weather patterns. Furthermore, stresses habitually occur as combinations of two or more. The goals of this review are to: (1) provide an in-depth description of the existing knowledge of quinoa's tolerance to different abiotic stressors; (2) summarize quinoa's physiological responses to these stressors; and (3) describe novel advances in molecular tools that can aid our understanding of the mechanisms underlying quinoa's abiotic stress tolerance.
藜麦（藜属）是一种基因多样的安第斯作物，因其营养和健康益处以及适应不同环境的能力而受到全球特别关注，这些环境包括贫瘠土壤、盐碱地以及干旱胁迫的边缘农业生态系统。干旱和盐度是藜麦研究最多的非生物胁迫；然而，对其他重要胁迫因素，如高温、低温、重金属和UV - B光辐射的研究却极为有限。在过去几十年中，不可预测的天气模式增加加剧了非生物胁迫的发生。此外，胁迫通常以两种或更多种组合的形式出现。本综述的目的是：（1）深入描述藜麦对不同非生物胁迫因子耐受性的现有知识；（2）总结藜麦对这些胁迫因子的生理反应；（3）描述有助于我们理解藜麦非生物胁迫耐受性潜在机制的分子工具的新进展。
