Climate change poses significant threats to agriculture globally, particularly in arid and semi-arid regions where drought stress (DS) is most severe, disrupting ecosystems and constraining progress in agriculture and horticulture. Roses, valued for their aesthetic appeal, are highly susceptible to abiotic stresses, especially DS, which markedly reduces flower quantity and quality. Under DS conditions, roses exhibit diverse morphological, physiological, biochemical, and molecular adaptations that vary across species. This review examines the effects of DS on rose growth, yield, and physiological traits, including gas exchange, photosynthesis, phytohormone dynamics, and water and nutrient relationships, alongside their biochemical and molecular responses. Furthermore, DS impacts the biosynthesis of secondary metabolites, notably reducing the yield and quality of essential oils in roses, which are critical for their commercial value in perfumery and aromatherapy. Additionally, the impact of DS on rose flower quality and post-harvest longevity is assessed. By elucidating these diverse responses, this review provides a framework for understanding DS effects on roses and offers insights to develop strategies for mitigating its adverse impacts.
气候变化对全球农业构成重大威胁，在干旱胁迫最为严重的干旱和半干旱地区尤其如此，它破坏生态系统，制约农业和园艺的发展。玫瑰因其美学价值而备受珍视，但极易受到非生物胁迫的影响，尤其是干旱胁迫，这会显著降低花朵的数量和质量。在干旱胁迫条件下，玫瑰会表现出不同的形态、生理、生化和分子适应性，这些适应性因品种而异。本综述探讨了干旱胁迫对玫瑰生长、产量和生理特性的影响，包括气体交换、光合作用、植物激素动态以及水分和养分关系，以及它们的生化和分子反应。此外，干旱胁迫影响次生代谢产物的生物合成，显著降低玫瑰中精油的产量和质量，而精油对玫瑰在香水和芳香疗法中的商业价值至关重要。此外，还评估了干旱胁迫对玫瑰花朵品质和采后寿命的影响。通过阐明这些不同的反应，本综述提供了一个理解干旱胁迫对玫瑰影响的框架，并为制定减轻其不利影响的策略提供了见解。
