Background and Aims
In the light of possible climate change, a crucial aspect for future Mediterranean Europe viticulture is the selection of new rootstocks exhibiting adaptability to drought and salt stress. In this context and considering recent literature, it is fundamental to increase our knowledge of the biochemical and physiological events that characterise stress responses in grapevine roots. In this study, leaf and root responses induced by water stress (WS) and sodium chloride (NaCl) exposure in a new selected genotype, named M4 (Vitis vinifera × V. berlandieri) × V. berlandieri cv. Resseguier n. 1), were compared with those of the commercial rootstock 101.14.
