Drought is a critical factor constraining plant growth in arid regions. However, the performance and adaptive mechanism of Atriplex canescens (A. canescens) under drought stress remain unclear. Hence, three-year experiment with three gradients was performed common garden, leaf functional traits, biomass partitioning patterns A. were investigated. The results showed that had significant effects on traits. maintained content malondialdehyde (MDA) activity superoxide dismutase (SOD), but peroxidase (POD) catalase (CAT) decreased, proline (Pro) soluble sugar (SS) increased only heavy stress. Under stress, leaves became smaller denser, specific area (SLA) dry matter (LDMC) stability. Total decreased 60% to 1758 g seed 10% 20% non-stress group, there no difference root biomass. More allocated allocation ratio doubled from 9.62% 19.81% drought, root/shoot (R/S) 0.11 0.25. MDA significantly negatively correlated biomass, while SPAD positively total aboveground organs POD, CAT, Pro SS correlations ratio. morphological traits related shape weight allocation. Our study demonstrated made tradeoffs between potential tolerance evolved conservative strategy. These findings provide more information for an in-depth understanding adaption strategies guidance planting sustainable management semi-arid

Abstract Aim Plant functional traits are frequently proposed as influential factors in species distribution. However, there is a gap assessing how plant resource‐economic relate to the size and shape of species' geographical range, what extent these relationships conserved over evolutionary history. Specifically, an acquisitive strategy (characterized by heightened metabolism, shorter lifespan quicker generation turnover) may promote isotropic range formations, resulting less elongated larger ranges. Here, I tested this link using data from 98 native European tree species. Location Palaearctic. Time period Present. Major taxa studied Trees. Methods used chorological maps quantify two independent attributes: area elongation. considered 28 linked resource‐use measured above‐ below‐ground organs. multi‐response phylogenetic mixed models calculate conservative trait correlation (CTC) phylogenetically (IND) component each with Results Range positively correlated resource strategies, while elongation strategies. This pattern was consistent across examined but statistically significant seven out traits, including specific leaf area, root mycorrhizal colonization. Traits related nutritional status exhibited weakest attributes. Significant correlations were more frequent IND often showed contrasting trends compared CTC. Main conclusions emerges relevant factor gain insights on shapes distribution, alongside established drivers such dispersal limitation climatic tolerance. Trait‐range driven processes leaving weak signature. These result direct selection, where impact attributes, or indirect effects, co‐variation ranges environmental niche optima.
