A total of 54 sample plots were established along an elevational gradient from 50 to 550 m across three different regions, with 100 m elevational intervals. Two-way ANOVA, regression analysis, Tukey\u2019s HSD multiple comparisons, and generalized additive models (GAMs) were used to examine distribution patterns. (1) Individual bamboo biomass followed a unimodal pattern with increasing elevation, peaking at 150 m (16.20 \u00b1 3.88 kg culm\u22121), which was significantly higher than at other elevations (p = 0.048). Allometric covariance analysis showed that the b value did not differ significantly among elevations (p = 0.882), indicating a stable diameter at breast height (DBH)-biomass relationship. (2) Stand biomass was highest at 50 m (34.75 \u00b1 10.97 t\u00b7ha\u22121) and declined with elevation to 18.54 \u00b1 7.13 t\u00b7ha\u22121 at 550 m, revealing a decoupling from the elevational trend of individual biomass. (3) Branch and leaf dry mass allocation exhibited a \u201chigher at both ends, lower in the middle\u201d pattern. Culm allocation was highest at 150 m (80.3%), though differences among elevations were not statistically significant (p = 0.591). (4) Stand density decreased with elevation, while mean DBH first increased and then decreased, reaching a maximum at 450 m (9.77 cm). Differences in stand density and DBH among elevations were highly significant (p &lt; 0.001). (5) ANCOVA showed that after controlling for mean DBH, the effect of elevation on individual biomass was substantially weakened (p = 0.051), with partial \u03b72 declining from 0.48 to 0.21 (a 56% reduction), indicating that DBH accounted for a substantial portion of the elevation effect on individual biomass.The individual biomass of Moso bamboo in central-southern Jiangxi peaked at approximately 150 m elevation. Elevation was associated with biomass mainly through its association with DBH (a size effect), rather than through changes in allocation ratios or allometric relationships. The pathway \u201celevation\u2192DBH\u2192individual biomass\u201d appears to be the primary mediating pathway explaining the decoupling, although a causal interpretation requires further experimental validation. These findings provide a theoretical basis for elevation-differentiated management of Moso bamboo forests.<\/jats:p>","DOI":"10.3390\/plants15142190","type":"journal-article","created":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T09:00:52Z","timestamp":1784278852000},"page":"2190","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Elevational Gradient on Biomass Allocation Patterns of Moso Bamboo Forests in Central-Southern Jiangxi, China"],"prefix":"10.3390","volume":"15","author":[{"given":"Shan","family":"Li","sequence":"first","affiliation":[{"name":"International Centre for Bamboo and Rattan\/Key Laboratory of National Forestry and Grassland Administration for Bamboo & Rattan Science and Technology, Beijing 100102, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jialin","family":"Fan","sequence":"additional","affiliation":[{"name":"Beijing Jingnong Holding Group Co., Ltd., Beijing 100070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9393-933X","authenticated-orcid":false,"given":"Xiaotong","family":"Liu","sequence":"additional","affiliation":[{"name":"International Centre for Bamboo and Rattan\/Key Laboratory of National Forestry and Grassland Administration for Bamboo & Rattan Science and Technology, Beijing 100102, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiajun","family":"Liu","sequence":"additional","affiliation":[{"name":"International Centre for Bamboo and Rattan\/Key Laboratory of National Forestry and Grassland Administration for Bamboo & Rattan Science and Technology, Beijing 100102, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3511-6692","authenticated-orcid":false,"given":"Zhoubin","family":"Huang","sequence":"additional","affiliation":[{"name":"International Centre for Bamboo and Rattan\/Key Laboratory of National Forestry and Grassland Administration for Bamboo & Rattan Science and Technology, Beijing 100102, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingyao","family":"Zhang","sequence":"additional","affiliation":[{"name":"International Centre for Bamboo and Rattan\/Key Laboratory of National Forestry and Grassland Administration for Bamboo & Rattan Science and Technology, Beijing 100102, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guanglu","family":"Liu","sequence":"additional","affiliation":[{"name":"International Centre for Bamboo and Rattan\/Key Laboratory of National Forestry and Grassland Administration for Bamboo & Rattan Science and Technology, Beijing 100102, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Liese, W., and K\u00f6hl, M.
