The damage caused by climate change and global warming can lead to significant economic losses in economically valuable plant species. Recent studies have shown that exogenous putrescine application is an effective strategy for enhancing tolerance various environmental stress factors; however, no previous research has examined the effects of on drought grapevines. In this study, applied at concentrations 0, 0.05, 0.1, 0.2 mM 1103 Paulsen American grape rootstocks under (at 30–40% field capacity) normally irrigated plants 70–80% were investigated. These findings indicated improved growth characteristics physiological parameters grapevine saplings stress. Under these conditions, 0.1 increased shoot length 2.24-fold, fresh weight 16.60-fold, root 2.35-fold dry 2.22-fold while decreasing index 2.38-fold. conclusion, study demonstrated potential enhance grapevines, emphasizing need further area. future research, grapevines should be investigated, considering wider range underlying genetic molecular mechanisms different
