1. Introduction Vitis vinifera L., the common grapevine, is a keystone species within the Vitaceae family, cultivated primarily for wine, table grapes, and raisins [1]. The Mediterranean region represents 39% of the total vineyard surface (7.3 million hectares), with Spain, France, Italy, and Turkey being major producers [2]. Mediterranean viticulture faces two significant environmental challenges: recurring drought and rising soil salinity [3,4,5].
