Drought threatens the stability of artificial black locust forests on Loess Plateau, yet there is limited research physiological and metabolic responses mature to drought stress. This study employed a throughfall exclusion system—i.e., moderate (40% reduction), extreme (80% 0% reduction for control—to analyze leaf microstructure, relative water content (RWC), osmotic adjustment substances, hormone levels, flavonoid metabolites in under controlled The results demonstrated that as stress intensified, stomatal aperture density decreased, while trichome length exhibited significant increases. MDA, proline, IAA, substances (soluble protein, reducing sugar, total sugar) first increased then decreased intensified. A 245 compounds were identified through metabolomic analysis, among which 91 differential expression treatments. Notably, 37 flavonoids, including flavonols glycosylated derivatives, consistently upregulated. These findings suggest can lead accumulation flavonoids. explored trees stress, offering insights selecting drought-resistant species vegetation restoration informing ecological management practices arid regions.
