Consequently, the present study evaluates particleboard composites made from pine (PT) and eucalypt (ES) wood waste remnants bonded with castor oil-based polyurethane (PUR) and reinforced with recycled polystyrene (PS). A particleboard was manufactured by hot pressing and its physical, mechanical, morphological, and thermal properties were determined. By incorporating PS, moisture resistance, dimensional stability, and thermal properties were significantly improved. According to mechanical tests, the modulus of rupture (MOR) and modulus of elasticity (MOE) increased with increasing PS content, while the perpendicular tensile strength (PTS) decreased but remained above the minimum required by NBR 14810–1 of 0.35 MPa. The PT-ES/PUR composite containing 50 wt% PS exhibited the best overall performance, achieving MOR and MOE values of 24.40 MPa and 3.150 GPa, respectively. Additionally, this formulation showed reduced thickness swelling (9.65 %) and water absorption (24.04 %) when compared with the PS-free specimen. By scanning electron microscopy, it was demonstrated that higher PS concentrations resulted in improved interfacial adhesion and a more effective polymeric encapsulation of wood particles. Based on thermogravimetric analysis, PS acts as a thermal barrier, delaying lignocellulosic degradation and enhancing the thermal stability of composites. Based on these results, it has been demonstrated that recycled PS can reinforce and reinforce, thereby contributing to the development of sustainable particleboards that can be used for indoor and semi-exposed applications, such as furniture components.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"16 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147587803","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}

While biodegradable polymer-coated slow-release fertilizers offer a promising alternative, their performance is often hampered by rapid nutrient release. This study developed a new biochar-amended coated urea (0.25BC-PVA/SA-SRU) using a polyvinyl alcohol/sodium alginate (PVA/SA) hydrogel matrix to enhance nitrogen utilization in wheat. A comprehensive field experiment demonstrated that 0.25BC-PVA/SA-SRU significantly increased grain yield by approximately 36.2% and 25.5% compared to conventional urea and unamended PVA/SA-coated urea, respectively. Mechanistic insights revealed that the biochar amendment served as a multifunctional modifier within the hydrogel: its microporous structure and adsorption capacity decelerated urea diffusion and minimized burst release, while its hydrophobic nature regulated water infiltration, collectively synchronizing nitrogen release with crop demand. This tailored release kinetics, validated by soil column leaching tests, underpinned a remarkable NUE of 51.0%—more than double that of conventional urea (24.7%). Furthermore, the coating decomposition and biochar incorporation created synergistic soil benefits: they enhanced cation exchange capacity and organic matter content, while the biochar's porous architecture served as a microbial hotspot, significantly increasing bacterial diversity and enriching key taxa involved in nitrogen cycling. Life cycle assessment confirmed the broad environmental advantages of 0.25BC-PVA/SA-SRU, showing consistent impact reductions across multiple categories. The integration of biochar into a biodegradable coating thus establishes a synergistic strategy for sustainable intensification of cereal production, simultaneously addressing agronomic productivity, soil ecological health, and environmental sustainability.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"33 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147507344","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}

Although smooth bromegrass (<em>Bromus inermis</em> L.) demonstrates a certain level of tolerance, the candidate genes responsible for its resistance to saline-alkali stress remain largely unidentified. This study initially developed a high-quality, full-length reference transcriptome by sequencing a combined RNA sample, resulting in 124,616 unique transcripts with high completeness. Of these, 12,290 genes were annotated using various databases. Using this reference, transcriptome analysis was conducted on samples collected at different time points under salt and alkali stress. Analysis of differentially expressed genes, combined with physiological data and functional enrichment, indicates that 12 h is a key threshold in the response to saline-alkali stress. We identified 71 and 73 differentially co-expressed genes under salt and alkali stress conditions, respectively, with 15 upregulated genes shared by both stress types. KEGG enrichment analysis identified dynamic expression patterns in pathways crucial for stress adaptation, including phenylpropanoid and flavonoid biosynthesis, photosynthetic antenna proteins, plant hormone signaling, and nitrogen metabolism. Among these pathways, we identified six photosynthetic antenna protein genes, two <em>SnRK2</em> genes, and one <em>IAA</em> gene that were consistently differentially expressed across different growth stages.
