  "abstract": "Introduction: Geographic variation in bamboo culm traits can reveal associations between source environments and biomechanical performance and can help prioritize germplasm for further testing.\n\nMethods: We quantified 11 physical and mechanical traits in 31 geographic sources of Dendrocalamus latiflorus from nine provincial-level regions of China and related source-level means to 25 geographic and climatic variables. Analyses combined coefficients of variation, Pearson correlations with Benjamini–Hochberg false-discovery-rate correction, partial least squares regression (PLSR) with leave-one-out cross-validation and 1,000 bootstrap resamples, Moran’s I tests of residual spatial autocorrelation, principal component analysis, objectively validated Ward clustering, and a seven-trait entropy-weighted TOPSIS evaluation with equal-weight sensitivity analysis.\n\nResults: Trait coefficients of variation ranged from 7.1% to 24.4%. After correction of 100 Pearson tests, 32 associations remained significant at q < 0.05; the strongest was between precipitation of the warmest quarter (BIO18) and compressive strength parallel to grain (CSPG; r = 0.658, q = 0.0058). PLSR showed the highest cross-validated performance for CSPG (Q ² = 0.599), moderate performance for air-dry and oven-dry density, and weak performance for modulus of rupture (Q ² = 0.076). Raw density and CSPG values were spatially autocorrelated, but PLSR residuals were not. Two validated trait classes showed no significant differences in six key source-climate variables. Entropy-weighted TOPSIS ranked P6, P4, and P19 highest; equal weighting produced strongly concordant ranks (Spearman rho = 0.911).\n\nDiscussion: These results identify robust climate-associated trait patterns and candidate sources for further testing while avoiding causal inference from source-site sampling.",
