To establish a nitrogen fertilizer application and harvesting management system for multiple harvests of <em>Artemisia argyi</em>, this study combined 3 stubble periods, 4 nitrogen application rates, and 3 harvest times, with 12 treatments for the first crop, 15 treatments for the second crop, and 21 treatments for the third crop, and systematically analyzed the yield and quality of <em>Artemisia argyi</em> leaves. The results showed that the yield of <em>Artemisia argyi</em> leaves in the three stubble periods was in the order of the first crop &gt; the second crop &gt; the third crop. The overall quality of the first crop leaves was the best; the second crop leaves had a higher output rate of moxa; and the third crop leaves had higher contents of chlorogenic acid, neochlorogenic acid, and cryptochlorogenic acid. Compared with the no-nitrogen application treatment, the “0.67 g·pot⁻¹ (268 kg·ha⁻¹) nitrogen application in the first crop + 0.67 g·pot⁻¹ (268 kg·ha⁻¹) nitrogen application in the second crop + no nitrogen application in the third crop” system increased the yield and quality of <em>Artemisia argyi</em> leaves in each stubble period and overall. Principal component analysis revealed that the first crop <em>Artemisia argyi</em> should be harvested 75 days after the sixth true-leaf stage. The optimal harvest time for the best quality under nitrogen application was 7 days earlier than that under no nitrogen application, and this harvest time significantly increased the yield and quality of <em>Artemisia argyi</em> leaves of the second and third crops (<em>P</em> &lt; 0.05). Additionally, excessive nitrogen application would reduce the yield of <em>Artemisia argyi</em> leaves and affect their quality. In conclusion, optimizing the nitrogen application rates and harvest time for different stubble periods can effectively improve the quality and yield of <em>Artemisia argyi</em> leaves.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"236 ","pages":"Article 122021"},"PeriodicalIF":6.2,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145247623","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}

However, its unique composition, particularly its high starch content, makes it highly susceptible to fungal decay, which leads to a significant loss of its mechanical properties. In this study, Moso bamboo samples were colonized by four prevalent decay fungi: the white-rot species <em>Phanerochaete chrysosporium</em> and <em>Trametes versicolor</em>, and the brown-rot species <em>Gloeophyllum trabeum</em> and <em>Postia placenta</em>. The objective was to investigate the time-dependent changes in the structure and chemical composition of the bamboo to elucidate their degradation mechanisms. The results indicated that after a 16-week incubation, the white-rot fungus <em>Trametes versicolor</em> caused the highest mass loss of 55.1 %, while <em>Postia placenta</em> caused only 19.8 %; the pH of the bamboo samples decreased over time, with samples inoculated with brown-rot fungi exhibiting a more acidic nature; the relative crystallinity values incubated in <em>T. versicolor</em> and <em>Gloeophyllum trabeum</em> are 59.72 % and 45.09 %, respectively. Structural analysis revealed that brown-rot showed different degradation patterns from white-rot fungi by showing preferential attack of vessels and fibers. The results of chemical composition analysis and X-ray photoelectron spectroscopy (XPS) further proved that brown-rot fungi primarily degrade cellulose and hemicellulose. In contrast, white-rot fungi preferential attack in the order of vessels, parenchyma, and then fibers. Chemical analysis and XPS confirmed that <em>T. versicolor</em> selectively degrades lignin, leading to the exposure of microfibrils in the cell walls, thereby leading to an increase in the crystallinity of bamboo.This study demonstrates the different decay pathways of white-rot and brown-rot fungi in Moso bamboo. These findings are vital for the sustainable use of bamboo and wood residues, improving the longevity of bamboo composites, and developing new bioremediation solutions for bamboo waste.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"112 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145241475","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}

A systematic investigation was conducted to assess the effects of BP content and foaming conditions on foam properties. In addition, the mechanism of enhancement of foam's resistance to shrinkage using BP limiting strategy were elucidated. When the content of BP was 15 wt%, the foaming temperature was 100 ℃, and the foaming pressure was 12 MPa, the foaming ratio of the foam was 10.11 times, the density was 0.13 g/cm³ , and the shrinkage rate was significantly reduced from 68.57 % of pure PBAT to 5.24 % (a substantial reduction of 92.36 %). BP enhances the melt strength of PBAT and acts as the heterogeneous nucleation site to increase cell density, achieving synergistic resistance for foam shrinkage. The PBAT/BP foams exhibited outstanding resilience (can recover the original state after being folded, twisted, or compressed). Additionally, the prepared PBAT/BP foams showed similar thermal conductivity 28.85 mW/(m·K) to commercial polyurethane (PU) and polystyrene (PS) foams, offering ideal substitutes for fossil-based foams.

Seven agricultural residues were used as feedstocks, including oil palm wastes (palm mesocarp fiber, palm empty fruit bunch, and palm kernel shell), bagasse, betel nut, coconut fiber, and rice husks. Results demonstrated that the system can effectively perform with all biomass types with high-quantity and high-quality syngas production. The process revealed exceptional performance and efficiency, including the total maximum syngas yield range of 67.9–81.5 mmol/g_{dry biomass}, reaching 81.4–95.2 % of the theoretical total syngas yields, maximum energy upgrade factor (1.05–1.35), reaching 94.2–97.3 % of the theoretical values, and maximum carbon conversion (87.2–96.9 %). The feedstock types showed a significant influence on gasification outcomes. Palm oil empty fruit bunch, betel nut, and palm mesocarp fiber were promising candidates for solar gasification with their high volatile content and significant decomposition potential, followed by coconut fiber and bagasse. Nevertheless, palm kernel shell and rice husk were found to be unsuitable biomasses for continuous solar-steam gasification because of the issues of reduced gasification activity and reaction rate limitations, due to a high density for palm kernel shell and a high ash content for rice husk. A temperature of 1300 °C was recommended to carry out continuous solar-steam gasification, leading to the maximum solar-to-fuel energy conversion efficiency in the range 13.7–18.9 %.

Herein, a systematic analysis of the molecular mechanisms of terpenoid biosynthesis in the Sanqi flowers was performed using multiomics (GC-MS, LC-MS and transcriptomics) analyses. Totally, 41 and 42 types of volatile organic compounds (VOCs), predominantly classified as sesquiterpenoids, were present in Sanqi flowers from the PAS and PYS systems, respectively. Germacrene D was notably prominent in Sanqi flowers from the PAS system. Moreover, 154 metabolites of nonvolatile terpenoids were identified, which primarily included triterpenoid saponins (84.415 %) and triterpenoids (15.585 %). Cultivation system chiefly contributed to differences in the VOCs and non-VOCs of Sanqi flowers. A total of 45 and 49 differentially expressed metabolites were significantly upregulated in the early and full bloom stages, respectively, of Sanqi flowers from the PAS system. Furthermore, gypenoside XVII, gypenoside IX, notoginsenoside Fd, ginsenoside Rd, and chikusetsusaponin-FK1 were the major non-VOCs. Additionally, the <em>SQLE</em> and <em>GERD</em> genes directly regulated the biosynthesis of triterpenoids and sesquiterpenoids, respectively. The yeast one-hybrid system indicated that MYB61 transcription factor interacted with the <em>GERD</em> gene. Thus, Sanqi flowers of higher quality were obtained from the PAS system.
