Abstract Aims Environmental heterogeneity induced by altitudinal gradients shapes plant survival strategies. This study investigates how Gentianella turkestanorum (Gand.) adapts its stoichiometry (C, N, P) across elevations (2405.4–3000.6 m) under climatic and edaphic drivers. Methods We measured C, P contents ratios (C:N, C:P, N:P) in roots, stems, leaves, flowers, whole plants seven gradients, integrating climate soil data to analyze driving mechanisms. Results The results revealed that C N as well roots significantly increased with elevation, while floral content decreased. Stoichiometric showed declining C:N (in flowers) C:P leaves) whereas root N:P markedly (7.88–16.23), indicating stronger nitrogen limitation at lower altitudes weakened higher elevations. Climatic factors (mean annual temperature precipitation) predominantly drove stoichiometric variation (76.3%) stems (30.9%), (total nitrogen, pH) influenced leaves (17.3%) flowers (47.6%). Climate-soil interactions contributed most (25.9%). Whole-plant synchronously, elevated N:P, reflecting adaptive strategies of prioritizing allocation metabolic organs (roots optimizing resource use efficiency (reduced C:P). Conclusions reveals divergence multi-organ alpine plants, validating the temperature-physiology hypothesis. propose a novel climate-soil synergy mechanism organ-specific functional differentiation, offering theoretical foundations for nutrient management restoration degraded meadows
