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> &lt; 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 &gt; single phosphorus treatment &gt; 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). Optimizing the nitrogen and phosphorus ratio in fertilizer has the potential to promote the growth of <em>Pinus yunnanensis</em> seedlings.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"232 ","pages":"Article 121226"},"PeriodicalIF":5.6,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147855","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}

We also assessed the resin components in samples with different resin yields and conducted a correlation analysis between resin components and resin yield.

However, the structural and compositional origins for its relatively high permeability under ambient pressure remain unclear. This study relates the multiscale 3D structure of cells in vascular bundles to the permeability of bamboo using in situ X-ray computed tomography (μCT) and focused ion beam-scanning electron microscopy (FIB-SEM), while mass spectrometry imaging (MSI) is employed to correlate the microscale spatial distribution of chemical components with permeability. The study reveals a previously unknown behavior and mechanism of liquid permeation in bamboo, with sieve tubes (STs) and small vessels serving as the main pathways. Capillary effects are significantly more pronounced in small vessels than in MVs. The small vessels have an average length of 147.87 ± 45.17μm with a shape factor of 1.18 ± 0.22. The reduction in flow resistance caused by the presence of long cavities and smooth cell walls in the small vessels results in an increase in flow rate. High hemicellulose and low lignin content of STs enhance water interaction, thus promoting liquid permeation in bamboo. The mechanism of liquid permeation in bamboo provides valuable insights for the biomimetic design of engineering materials.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"232 ","pages":"Article 121255"},"PeriodicalIF":5.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144139388","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}
