We investigated how short-term N enrichment differentially modifies leaf functional traits, leaf stoichiometry, and nitrogen and phosphorus resorption efficiencies (NRE and PRE) in female and male Fraxinus velutina Torr. using a field canopy-spray experiment with two N addition levels. Although N addition consistently promoted leaf structural traits, neither sex nor the N\u00a0\u00d7\u00a0S interaction significantly affected leaf morphological traits, suggesting that sexual dimorphism in this species manifests primarily in nutrient economy rather than leaf structure. Under N enrichment, P-related traits exhibited pronounced sex-specific responses, with significant N\u00a0\u00d7\u00a0S interactions: under high N, females increased leaf P concentration and exhibited lower N:P, whereas males increased leaf N concentration, resulting in higher N:P. N addition reduced NRE in both sexes, but PRE responses differed markedly: PRE declined progressively in males under elevated N, while females maintained a moderate reduction in PRE. SMA and multivariate analyses further showed that nutrient resorption in males was more strongly associated with current-season stoichiometric variation, whereas in females, nutrient resorption showed a stronger association with P status. Together, these findings identify P balance as the primary axis of sex-specific nutrient regulation under N enrichment, with females maintaining more stable internal P homeostasis than males. This distinction that underscores the need to account for plant sex in assessments of dioecious tree responses to increasing atmospheric N deposition.<\/jats:p>","DOI":"10.1093\/treephys\/tpag143","type":"journal-article","created":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T11:49:59Z","timestamp":1791460199000},"source":"Crossref","is-referenced-by-count":0,"title":["Sex-specific
