The evaluation and identification of high-vigor germplasms are essential for increasing soybean production capacity. Currently, there is no universally accepted evaluation system to test for soybean seed vigor. In this study, 11 seed vigor-related traits were measured across 126 soybean landraces via an artificial accelerated aging technique. The ratios of these 11 traits, which were calculated before and after artificial accelerated aging, were used as vigor indicators in principal component analysis (PCA), ultimately yielding two principal component factors. These factors were then combined via membership function standardization to calculate a comprehensive seed vigor evaluation value (<em>V</em> value), thereby establishing an evaluation system. Cluster analysis based on the <em>V</em> value was used to classify seed vigor into five levels and identify seven high-vigor germplasms: ZDD12322, ZDD06438, ZDD11951, ZDD08251, ZDD12436, ZDD02315, and ZDD15624. Through stepwise regression analysis, the optimal seed vigor predictive model was defined as <em>V</em> = −0.026 + 0.625 × RSL + 0.485 × RGI. This model revealed that the relative seedling length (RSL) and relative germination index (RGI) had significant positive effects on seed vigor. This study provides a valuable framework for seed quality control and selection, facilitating presowing vigor assessments to increase soybean planting efficiency and yield.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"224 ","pages":"Article 120329"},"PeriodicalIF":5.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, there is a scarcity of research on sustainable approaches in bone scaffold fabrication, warranting further exploration given their biocompatibility. This study addresses these issues by fabricating water-stable, glutaraldehyde (GA) crosslinked soy protein isolate (SPI)/carboxymethyl cellulose (CMC) porous scaffolds using oil palm empty fruit bunch (OPEFB) waste as the starting material. The scaffolds were prepared through blending, crosslinking, and freeze-drying processes, followed by several characterisation experiments to assess morphology, porosity, mechanical properties, and degradation rate. The results showed that the SPI/CMC scaffolds exhibited a rough surface morphology with an average pore size ranging from 65 ± 13 μm to 99 ± 8 μm. The porosity of the SPI/CMC-based scaffolds was higher than that of the SPI-based scaffolds, though the increased porosity led to a lower Young’s modulus. A decrease in Young’s modulus was observed with increasing CMC content, attributed to the inefficiency of SPI-GA crosslinking. The scaffolds demonstrated a slow degradation profile over 35 days of incubation in simulated body fluid (SBF), indicating their potential to retain structural integrity over extended periods. Additionally, a fluctuating weight change due to calcium phosphate deposition suggested the bioactive properties of the scaffolds<em>.

The present study aimed to investigate the utilization of a previously untested soft template-assisted foaming technique in the fabrication of biopitch-based carbon foam that provided brightness to the research in the literature. The hornbeam sawdust pitch-based carbon foams were formed by incorporating the non-ionic surfactant P123 into the synthesis solution. The research focused on understanding the effects of the foaming technique (conventional or template-assisted), template ratio, and chemical activation on the foam’s physical, chemical, and mechanical properties via several analytical and characterization test methods. Raman spectroscopy, scanning and transmission electron microscopy analyses were performed to characterize the pore structures and carbon hybridization types, deducing highly aligned graphitic-like structures. Moreover, the mechanical strength of carbon foam was also enhanced via soft-template addition before foaming and diminished after chemical activation. The highest mechanical strength of 9.79 MPa with suitable thermal conductivity of 0.044 W/m.K and the lowest porosity of 71.41 % were attained when the template amount was 1 wt%. Surface areas of activated carbon foams ranged from 92.3 to 1121.2 m²/g. Accordingly, the adjustable pore structures of the developed materials allowed them to be considered promising adsorbents according to the need to remove pollutants of different sizes.

The investigation utilizes XRD, FTIR, SEM and EDS analysis to gain insights into these properties.

In this study, we performed integrative metabolomic and transcriptomic analyses to elucidate the anthocyanin biosynthesis pathway in <em>Rhododendron rex</em>, which is differentially activated between the contrasting colored tissues of the petals (blotches versus backgrounds). Flavonoids were identified as the most abundant metabolites in <em>R. rex</em> petals; anthocyanins such as pelargonidin, cyanidin 3,5-di-<em>O</em>-glucoside (cyanin), cyanidin 3-<em>O</em>-glucoside (chrysanthemin), and delphinidin were significantly enriched in the blotch regions when compared to the background counterparts.

Furthermore, the combined regulation of flavonoid and lignin biosynthesis by <em>CHS</em> and <em>HCT</em>, as well as that of anthocyanin and flavonols by <em>DFR</em> and <em>FLS</em>, demonstrates that the metabolic balance is maintained through the regulation of the structural gene expression in response to competition for shared precursors involved in the biosynthesis of some secondary metabolites in plants.
