Recent research has extensively covered the effects of climate change factors, such as elevated CO2, rising temperatures, and water deficit on grapevine (Vitis spp.) biology. However, assessing the impacts of multiple climate change-related stresses on this crop remains complex due to interactive effects among environmental factors, and the regulatory mechanisms that underlie these. Consequently, there is a substantial discrepancy between the number of studies conducted with a single factor or two factors simultaneously, and those with a more holistic approach. Changes in crop phenology in response to temperature have been a major focus of many studies. We highlight how the impact of rising temperatures will be enhanced during specific developmental periods, such as grape ripening. However, how these shifts may result in deleterious effects on yield and quality deserves further research. Rising temperatures will most certainly continue to represent a substantial threat to viticulture due to its effects on grape phenology, composition, and crop water requirements. Nevertheless, elevated CO2 may offer some relief through increased water use efficiency, as shown in recent studies. Hormones play a major role within the repertoire of regulatory mechanisms that plants possess, with crosstalk between hormones explaining the effects of combined stresses. In fact, growth regulators can fine-tune stress responses depending on the multiple stresses present. This review focuses on the interaction of climate change factors across viticultural areas of the globe, and how multi-stress responses are mediated by abscisic acid and jasmonate, with emphasis on the intricate interconnections of signalling among different plant hormones.
近期研究广泛涵盖了气候变化因素，如二氧化碳浓度升高、气温上升和水分亏缺对葡萄（葡萄属）生物学的影响。然而，由于环境因素之间的交互作用以及其潜在的调控机制，评估多种与气候变化相关的胁迫对这种作物的影响仍然很复杂。因此，单一因素或两个因素同时进行的研究数量与采用更全面方法的研究数量之间存在很大差异。作物物候对温度的响应变化一直是许多研究的主要焦点。我们强调在特定发育时期，如葡萄成熟期间，气温上升的影响将如何增强。然而，这些变化如何对产量和品质产生有害影响值得进一步研究。由于气温上升对葡萄物候、成分和作物需水量的影响，它肯定将继续对葡萄栽培构成重大威胁。尽管如此，如近期研究所表明的，二氧化碳浓度升高可能通过提高水分利用效率提供一些缓解。激素在植物拥有的调控机制中起着主要作用，激素之间的相互作用解释了复合胁迫的影响。事实上，生长调节剂可以根据存在的多种胁迫微调胁迫反应。本综述重点关注全球葡萄种植区气候变化因素之间的相互作用，以及脱落酸和茉莉酸如何介导多重胁迫反应，重点是不同植物激素之间信号传导的复杂相互联系。
