Water scarcity is an ecological issue affecting over 10% of Europe. It is intensified by rising temperatures, leading to greater evaporation and reduced precipitation. Agriculture has been confirmed as the sector accounting for the highest water consumption globally, and it faces significant challenges relating to drought, impacting crop yields and food security. Sustainable practices, precision irrigation, and the development of drought-resistant crops are essential for the mitigation of this threat. Effective, innovative solutions are crucial for optimizing water use for intensive crops such as cultivated strawberries ( × ). This study emphasizes the importance of identifying the genotypes most resilient to low water availability. Experimental trials involving reduced irrigation levels were set up to identify genotypes with a greater capacity to increase fruit quality and maintain fruit yield. Reduced water conditions positively influenced strawberry fruit quality, exhibiting improved citric acid, soluble solids, and color brightness linked to decreased water use, while firmness remained stable. Notably, the total phenolic content was most affected by stress, indicating strong antioxidant responses. With these interesting variations in fruit quality came a different response in plant yield. Plants belonging to the Lauretta and AN15,07,53 cultivars maintained a 98% fruit yield when grown under WS1 conditions. While the yield for the Francesca cultivar increased by 10% under the stressed WS1 conditions in comparison to the control conditions, water stress in the WS2 treatment caused a strong reduction in yield in all three genotypes. Overall, the findings emphasize the importance of identifying for each new cultivar the most appropriate water regime in order to amplify the quality of the fruit, thus maintaining high production standards and saving water.
水资源短缺是一个影响超过10%欧洲地区的生态问题。气温上升加剧了这一问题，导致蒸发量增加和降水量减少。农业已被确认为全球用水量最高的部门，并且面临与干旱相关的重大挑战，影响作物产量和粮食安全。可持续做法、精准灌溉以及抗旱作物的培育对于减轻这一威胁至关重要。有效的创新解决方案对于优化诸如栽培草莓（×）等集约作物的用水至关重要。本研究强调了识别对低水分可利用性最具韧性的基因型的重要性。设置了涉及降低灌溉水平的试验，以识别具有更大能力提高果实品质并维持果实产量的基因型。水分减少的条件对草莓果实品质产生了积极影响，表现出柠檬酸、可溶性固形物的改善以及与用水量减少相关的颜色亮度提高，而硬度保持稳定。值得注意的是，总酚含量受胁迫影响最大，表明有强烈的抗氧化反应。随着果实品质出现这些有趣的变化，植株产量也有不同反应。属于Lauretta和AN15,07,53品种的植株在WS1条件下生长时保持了98%的果实产量。虽然Francesca品种在胁迫的WS1条件下的产量相比对照条件增加了10%，但WS2处理中的水分胁迫导致所有三个基因型的产量大幅下降。总体而言，研究结果强调了为每个新品种确定最合适的水分管理方式的重要性，以便提高果实品质，从而维持高生产标准并节约用水。
