However, urbanization and increasing labor costs have led to the abandonment of Moso bamboo forests. Understanding the ecological parameters of Moso bamboo at both the individual plant scale and the plot scale is critical for promoting harmonious coexistence between humans and this species. This study investigated 98 Moso bamboo forest plots in southern China and collected data on the diameter at breast height (DBH), age, and height from 14,085 individual plants. Distribution patterns of individual Moso bamboo parameters were analyzed, with comparative assessments between on-year and off-year forests dynamics. On the basis of the differences in forest stands across the sample plots, the aboveground biomass was estimated, and the influencing factors were assessed, leading to the following conclusions: (1) The DBH of individual Moso bamboo is positively correlated with plant height until reaching a size threshold, beyond which both parameters stabilize. (2) Moso bamboo exhibits an on-year phenomenon at the plot scale, with dynamic changes primarily occurring in these on-year plots, including the growth of new bamboo and the selective logging of older bamboo. (3) With human intervention, the age distribution of Moso bamboo forests follows a regular pattern, with on-year plots exhibiting a ratio of 1:1:1 (indicating the proportion of bamboo in the 1st year, 3rd year and 5th year age classes), whereas off-year plots present a ratio of 1:1 (indicating the proportion of bamboo in the 2nd year and 4th year age classes). (4) The aboveground biomass dynamics in Moso bamboo forest plots are hierarchically governed by three key determinants: stand density(R<sup>2</sup>=0.78), the number of Moso bamboo of each age (R<sup>2</sup> from 0.17 to 0.35), and average DBH(R<sup>2</sup>=0.12). These findings provide empirical data to support carbon sequestration management and sustainable development of Moso bamboo ecosystems.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"232 ","pages":"Article 121262"},"PeriodicalIF":5.6,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DC is a Chinese herbal medicine with high medicinal value, and its dried rhizomes are widely utilized in traditional medicine. The primary active constituents of <em>A. lancea</em> include sesquiterpenoids and polyacetylenes, such as atractylodin, atractylon, and β-eudesmol. The preponderance of <em>A. lancea</em> available in the commercial market is cultivated in fields, resulting in diminished concentrations of active components and inconsistencies in the quality of the medicinal materials. Nonetheless, understory cultivation has been demonstrated to enhance the content of active components in <em>A. lancea</em> and to align its phenotypic characteristics more closely with those of the wild type. However, research on the molecular mechanisms underlying the formation of quality in <em>A. lancea</em> during understory cultivation remains limited. This study employed transcriptomic and metabolomic approaches to systematically investigate the gene expression and metabolite synthesis of <em>A. lancea</em> across diverse habitats. The results demonstrated that understory cultivation enhances farnesyl diphosphate (FPP) biosynthesis and increases the content of sesquiterpene-related metabolites by upregulating the expression of genes involved in terpene skeleton biosynthesis, while downregulating downstream sesquiterpene genes, such as <em>FLDH</em>, <em>ICMT</em>, and <em>FNTA</em>. Additionally, the content of atractylodin was elevated through the upregulation of <em>FAB2</em> and <em>FAD2</em> gene expression. In addition to identifying differentially expressed genes and metabolites, this study constructed the regulatory network between transcription factors, genes, and metabolites. Furthermore, it hypothesized the sesquiterpenoid biosynthetic pathway, exemplified by atractylon and β-eudesmol, as well as the polyacetylene biosynthetic pathway, represented by atractylodin.

The experimental design adopted a 3 × 3 full factorial design with two factors and three levels. The three levels of the two factors (N and P) were each combined in pairs, resulting in a total of 9 treatments. Results showed that, in comparison to the control (T1), the biomass accumulation and allocation patterns of <em>Pinus yunnanensis</em> seedlings were significantly different (<em>P</em> < 0.05) in different treatments. In general, regarding the biomass accumulation in the root, stem, and leaf of <em>Pinus yunnanensis</em>, the effects of different treatments presented as follows: combined nitrogen and phosphorus treatment > single phosphorus treatment > single nitrogen treatment. In addition, it can be concluded from allometric growth analysis that the linear fitting effect of aboveground biomass is the best, followed by leaf. The linear fitting effect of root biomass was not obvious. The 3D surface plot analysis demonstrates that with increasing time, the model fit improved significantly, indicating a time-dependent cumulative effect of fertilization. Correlation analysis revealed differential organ-nutrient relationships across treatments: nitrogen showed stronger associations with root and stem biomass, whereas phosphorus and nitrogen-phosphorus interaction were more closely related to leaf biomass. The findings revealed that amendment with nitrogen and phosphorus remarkably enhanced the biomass of <em>Pinus yunnanensis</em>. When compared, the combined application of nitrogen and phosphorus proved to be more advantageous than the single application of either nutrient, particularly in T5 (0.4 g N/plant + 3 g P/plant).
