The current study investigated the impact of cold stress on morphological, physiological, and phytochemical properties Juglans regia L. (J. regia) using in vitro microclone cultures. revealed significant stress-induced changes production secondary antioxidant metabolites. According to gas chromatography–mass spectrometry (GC–MS) analyses, conditions profoundly altered metabolism J. microclones. Although overall spectrum metabolites was reduced, key significantly increased. Notably, there a sevenfold (7×) increase juglone concentration. These findings are crucial for advancing walnut metabolomics enhancing our understanding plant responses abiotic factors. Additionally, results aid identifying role individual these processes, which is essential developing strategies improve resilience tolerance adverse conditions.
