Published: Jan. 2, 2025

Viticulture faces unprecedented challenges due to the rapidly changing climate, particularly in regions like Mediterranean Basin. Consequently, climate change adaptation strategies are crucial viticulture, with short-term being widely used despite increasing concerns about their sustainability, and long-term considered promising, though costly. A promising but understudied strategy is varietal selection, as grapevines exhibit vast intervarietal diversity untapped potential for climate-resilient varieties. By integrating research across plant physiology, biochemistry, histology, genetics, we can better understand traits behind grapevine’s capability adaptation. Several traits, including morphological, physiological, molecular aspects, have been shown be adapting environmental stresses such drought heat. studying abundant grapevine diversity, viticulture through selection immense. This review article focuses on of change. For this, will delve into regarding how affects growth grape quality responds stress conditions, followed by a summary different viticulture.
