In this study, Near Infrared Spectroscopy (NIRS) was applied to rapidly assess germplasm variability from whole seed of 699 samples, field-collected and assembled in four genetic and environment-based sets: one set of 300 varieties of a core-collection and three sets of 133 genotypes of an interspecific population, evaluated in three environments in a large spatial scale of two countries, Mbalmayo and Bafia in Cameroon and Nioro in Senegal, under rainfed conditions. NIR elemental spectra were gathered on six subsets of seeds of each sample, after three rotation scans, with a spectral resolution of 16 cm<sup>-1</sup> over the spectral range of 867 nm to 2530 ​nm. Spectra were then processed by principal component analysis (PCA) coupled with Partial least squares-discriminant analysis (PLS-DA). As results, a huge variability was found between varieties and genotypes for all NIR wavelength within and between environments. The magnitude of genetic variation was particularly observed at 11 relevant wavelengths such as 1723 ​nm, usually related to oil content and fatty acid composition. PCA yielded the most chemical attributes in three significant PCs (i.e., eigenvalues &gt;10), which together captured 93% of the total variation, revealing genetic and environment structure of varieties and genotypes into four clusters, corresponding to the four samples sets. The pattern of genetic variability of the interspecific population covers, remarkably half of spectrum of the core-collection, turning out to be the largest. Interestingly, a PLS-DA model was developed and a strong accuracy of 99.6% was achieved for the four sets, aiming to classify each seed sample according to environment origin. The confusion matrix achieved for the two sets of Bafia and Nioro showed 100% of instances classified correctly with 100% at both sensitivity and specificity, confirming that their seed quality was different from each other and all other samples. Overall, NIRS chemometrics is useful to assess and distinguish seeds from different environments and highlights the value of the interspecific population and core-collection, as a source of nutritional diversity, to support the breeding efforts.</p></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"9 2","pages":"Pages 132-141"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096242824000241/pdfft?md5=c346609e816dacff868dbdf230d628b2&pid=1-s2.0-S2096242824000241-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141046499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the molecular mechanisms that lead to those results have yet to be elucidated. The aim of this research was to improve the understanding of these mechanisms by characterizing the metabolic effects of sugarcane bagasse biochar on soybean germination. Three types of biochars were prepared by pyrolysis at 300 ​°C (SCB300), 400 ​°C (SCB400) and 600 ​°C (SCB600). Then, each one was mixed into sand at 1%, 3%, 5% (w/w) dose, respectively. The experiment was performed in 8 days of incubation, when the number of germinated seeds and the average radicle length were determined. To evaluate the metabolome, the dry biomass (DB) was subjected to extraction with a mixture of methanol-<em>d</em><sub>4</sub> and D<sub>2</sub>O (1:1 v/v). The extracts were submitted to metabolomics analysis by Proton Nuclear Magnetic Resonance.

Seven metabolites (alanine, asparagine, acetic acid, citric acid, glycerol, fatty acids and sucrose) were identified and quantified in DB extracts as the most influential finding for the separation of treatments. Taken together, these results strongly suggested that biochars accelerated the catabolism of triacylglycerols to sucrose and induced a slight osmotic stress.</p></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"9 1","pages":"Pages 60-68"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096242824000149/pdfft?md5=34617cd6225d9c55f479d1b7c932b9ea&pid=1-s2.0-S2096242824000149-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140271512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One factor regulating soil pH is the overuse of inorganic fertilizer. The increased use of fertilizers in soybean production not only raises sustainability concerns but also contributes to soil acidity. Therefore, the use of organic fertilizer could offer a solution for addressing both issues related to soil acidity and sustainability. The purpose of this study was to investigate the manipulation of soil pH using organic fertilizer for soybean production under acidic stress. The planting medium, consisting of a mixture of topsoil, rice husk charcoal, and organic fertilizer (in a ratio of 2:1:1), was supplemented with 0.5 ​g of NPK fertilizer as a basal treatment in each planting medium. To regulate the soil acidity to pH 4, we added FeSO<sub>4</sub> and allowed the mixture to incubate for 30 days. The results demonstrate that the application of three types of organic fertilizers chicken manure (P1), oil palm empty bunch fertilizer (P2), and vermicompost (P3) positively impacts the growth of three soybean varieties. The findings indicate that the application of P2 organic fertilizer can increase vegetative growth almost 50% in soybeans on acidic soil, including plant height, leaf count, and root length. Meanwhile, applying P3 organic fertilizer can boost reproductive growth responses in soybeans on acidic soil, such as pod number (from around 0-4 unit to 42–51 unit), grain number (from around 0-5 unit to 88–90 unit), and grain weight (from around 0–0.37 ​g to 12–25 ​g).

The results showed that the moisture and polysaccharide content of sesame paste was increased as the DFGP increased. Additionally, the hardness, adhesiveness, and chewiness of the sesame paste was improved, while the presence of particles with small particle size (1–100 ​μm) was decreased. The rate of oil precipitation was reduced by 28.99% when the amount of DFGP was 6%. The sesame paste samples exhibited pseudoplastic behavior, demonstrating shear thinning. As the shear rate increased, the apparent viscosity of sesame paste gradually decreased. Both the storage modulus (G′) and the loss modulus (G″) increased as the shear frequency increased. The microstructure observation revealed that protein and oil were evenly distributed in the sesame paste system, and the addition of DFGP enhanced the bonding between oil and protein. This study can provide valuable references for high-quality sesame paste products in the food industry.</p></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"9 1","pages":"Pages 1-7"},"PeriodicalIF":0.0,"publicationDate":"2024-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096242824000101/pdfft?md5=666c2ac94842e0d75f915a8a2f0a9572&pid=1-s2.0-S2096242824000101-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139944939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
