To optimize the extraction process, single-factor studies and a Box-Behnken design were utilized, and the effects evaluated of various parameters on total phenolic content (TPC), total flavonoid content (TFC), DPPH radical scavenging activity, ferric-reducing antioxidant power (FRAP), and tyrosinase inhibition. Optimal conditions were obtained at 180 °C, 40 % solvent concentration, with a liquid-to-solid ratio of 50.23 mL/g, resulting in TPC, TFC, DPPH, FRAP, and significantly higher tyrosinase inhibition compared to ethanol-based extraction (p < 0.05). The liquid chromatography analyses identified caffeine and chlorogenic acid as primary bioactive compounds, alongside 12 additional bioactive compounds. Furthermore, at a concentration of 5 mg/mL, the BG-MAE extract demonstrated non-toxic, reduced melanin content, and inhibited cellular tyrosinase activity. This study highlights the potential of BG-MAE for producing bioactive compounds from CS in antioxidant and whitening cosmetic applications.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"46 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143192569","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, breeding cotton with improved fibre quality constitutes a major challenge due to the limited genetic diversity and close genetic linkage among modern cotton varieties. In this study, we anchored three quality-related QTLs, qFS-D06–1, qFM-D03–1, and qFM-D06–2, using a secondary F2 population constructed from the chromosome segment substitution line (CSSL) HY2654, which has significantly superior fibre micronaire (FM) and fibre strength (FS) value. The QTLs demonstrated definitive overlap with two major introgression segments identified on chromosome D03 and D06. The qFS-D06–1 locus, which accounts for 8.88 % of FS variation, was further fine-mapped to a 1.75 Mb interval on chromosome D06. Twelve genes located in this QTL region exhibit significantly differential expression in both HY2654 and its donor parent Gossypium barbadense acc. 3–79. Four of these genes, which have their orthologues generally known to be involved in cell growth and in physiological and biochemical processes relevant to fibre development, are expressed in fibres of all sampling periods and could be focused upon in further research. The current research could provide a strategy for accelerating the acquisition of the map-based identification of genetic features that underlie complex qualities. Further development of this foundation will put novel insights into important agronomic traits of plants.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"25 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143192682","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}

In this study, we systematically investigated the characteristics of coke on biochar-based catalysts (BC) during microwave-assisted catalytic pyrolysis of biomass. The morphology, pore structure, thermal stability, and composition of coke were thoroughly analyzed. Our findings revealed that both the degree of graphitization and the extent of coke formation on BC increased with rising reaction temperatures and prolonged reaction durations. Specifically, the BET surface area of fresh BC decreased from 108.44 m²/g to 56.26 m²/g after being subjected to 650°C for 80 minutes. Correspondingly, the proportion of inert coke (C₃) increased markedly from 15.90 % to 63.80 %. Notably, crystal-like coke structures were observed on the surface of BC. To quantify and evaluate variations in coke formation, we introduced a novel metric termed the “coke level,” which provides a graphical and quantitative assessment of both the amount and nature of coke present on the catalyst. Soluble coke generated under high-temperature and prolonged reaction conditions predominantly consisted of phenolic compounds. Microwaves can excite plasma, which in turn activates coke, inhibits its growth, and promotes its reaction with the surrounding environment. For instance, after treatment at 650°C for 80 minutes, the coke deposition on BC was only 3.99 wt%. These results demonstrate that the microwave field significantly enhances the catalyst’s service life and economic viability by reducing coke accumulation and improving catalyst efficiency.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"47 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143192686","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 developed flexible, rule-based climatic suitability indices (CSIs) using the maximum likelihood method, designed for specific phenological stages, to evaluate dynamic climatic suitability for crops. Based on these indices, we implemented a classification-regression-reclassification strategy to assess the annual climatic status (ACS) and predict short-term climatic suitability. The adaptability of this workflow is evident in its ability to integrate CSIs for various crops, effectively addressing the diverse needs of regional assessments. This study enables the use and comparison of machine learning models, including support vector machines (SVM/SVR), random forest, and gradient boosting trees (XGBoost), to identify the most effective model for classifying and predicting ACS in different regions. Using cotton in Xinjiang as a case study, SVM-XGBoost and SVM-SVR strategies were selected for short-term ACS prediction, achieving accuracy rates between 81.7 % and 91.0 %. From 1991 to 2020, the analysis identified crop yield potential and key factors, with an increase in normal years within suitable areas, indicating climatic adaptability. Sensitivity analysis revealed the influence of temperature suitability on cotton yield, particularly during seedling and boll formation stages in highly suitable areas for cultivation. Moreover, it emphasized precipitation and temperature during sowing to emergence and boll stages in moderately suitable areas. The workflow enhances generality and interpretability, providing a foundation for climate impact research and crop adaptation planning. Future research could incorporate new data sources, additional crop indicators, and various machine learning algorithms to enhance the generality and stability of the model.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"9 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143192681","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}

Exogenous application of plant growth regulator abscisic acid can effectively enhance crop drought resistance. However, the photo-instability of abscisic acid and the limited efficacy of conventional dosage forms limit its application in the field. To cope with this challenge, a pH-responsive composite ABA@MIL-100(Fe) was prepared based on the metal-organic framework MIL-100(Fe) to achieve precise abscisic acid release by harnessing pH fluctuations that occur as a physiological response in the crop's microenvironment during drought stress. The ABA@MIL-100(Fe) composite exhibited a hydrated particle size of 162.3 nm and an abscisic acid loading rate of 22.2 %. Meanwhile, ABA@MIL-100(Fe) showed excellent pH-responsive release characteristics. At pH 7.2, the release of abscisic acid from ABA@MIL-100(Fe) reached 70.5 % after 3 h, which was higher than that after 25 h under acidic conditions. Under UV irradiation for 9 h, free abscisic acid experienced considerable degradation with a rate as high as 44.9 %, whereas only 12.5 % degradation was observed for encapsulated abscisic acid within ABA@MIL-100(Fe). In bioassay trials, both foliar smearing and spraying of ABA@MIL-100(Fe) notably improved drought tolerance in cotton seedlings. The promoting effect of MIL-100(Fe) was also observed at the germination stage of cotton seeds. These results suggest that ABA@MIL-100(Fe) can be used as an intelligent delivery system of photosensitive pesticides to achieve controlled release and improved photolysis resistance under drought conditions, and can be applied for effective drought stress mitigation.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"40 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143124400","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}

This study focuses on modifying cellulose acetate (CA)-based waterborne polyurethane (WPU) sand-fixing agents by incorporating glycerol triglycidyl ether (GTE) and glycerin (GL). These additives can react with the hydroxyl groups in CA, forming hydrogen and ether bonds in the CA/WPU system, thereby improving the antifreezing abilities of the sand-fixing agents. Furthermore, the free hydroxyl groups in the modified CA/WPU system can interact with SiO2 in sand, leading to the formation of a strong dual-network structure. Compared with competing products, the CA/WPU-based sand-fixing agents developed in this research showed superior antifreezing and durability abilities, enhanced resistance to wind-blown sand and water, as well as a certain degree of water retention durability. The primary volatile substances of thermal degradation include water vapor, NH3, and CO2. CA/WPU/GTE and CA/WPU/GTE/GL0.5 (CA(-OH)/GTE/GL = 2/1/1) formulations exhibited superior degradation performance compared with CA/WPU/GL and CA/WPU/GTE/GL1.

With a consolidation strength of 1.76 MPa at 27°C, CA/WPU/GTE is ideal for alpine regions where plant survival is notably challenging. Conversely, CA/WPU/GTE/GL0.5, which had an appropriate consolidation strength of 1.56 MPa at 27°C, is fitting for alpine areas with existing plant life.
