Durum wheat was grown in semi-hydroponics with 100 nM Cd (Cd+) or at a background concentration of Cd (Cd-). Starting from stem elongation, the plants exposed to 100 nM Cd received a standard supply of S (S100), a reduced supply of S (S20) or were subjected to S deprivation (S0). Plants were sampled at the early milk development stage (Z71) and the early ripening stage (Z91) to assess differences in plant growth, Cd uptake and partitioning among organs, as well as net remobilization of Cd in the different treatments. Durum wheat growth was not affected by exposure to 100 nM Cd, and the root-to-shoot translocation of Cd was more restricted in the Cd + treatment than in the Cd-treatment. Reducing or stopping the supply of S did not affect durum wheat growth but enhanced S remobilization from almost all plant parts, including the roots. Stopping the supply of S resulted in a 35 % increase in the concentration of Cd in the grains. The proportional decrease in the concentrations of S and Cd in the roots of S-deficient plants between Z71 and Z91 suggests that Cd remobilization is associated with S remobilization in the roots of durum wheat. Sulfur deficiency promoted Cd accumulation in durum wheat grains likely due to enhanced remobilization of S and Cd in the roots of S-deficient plants.</div></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"23 ","pages":"Article 102235"},"PeriodicalIF":6.2,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144763670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Avocado seed starch exhibited the greatest concentration of amylose (30.87 %) and the minimal protein content (2.31 %), with a reddish tone was likely linked to bioactive compounds. Its starch granules presented an oval shape (26.97 × 11.74 μm), larger than the predominantly polyhedral granules of lucuma seed starch (9.87 μm). The highest amylose content was associated with larger values of gelatinization (T₀ 67.78 °C, T_p 73.90 °C, T_c 78.36 °C), hardness (24.62 N), cohesion (0.64), and gumminess (18.93 N). FT-IR analysis of rice husk displayed characteristic peaks associated with the presence of cellulose, hemicellulose, lignin, and silica. Potato starch was partially substituted with lucuma and avocado seed starches and reinforced with rice husk fibers to produce biodegradable trays via thermo-pressing. Adding rice husk fibers reduced expansion of starch, thereby making the internal structure of trays more compact and improving their physicochemical and mechanical properties. The incorporation of fibers increased the browning rate, especially those containing avocado or lucuma seed starch, probably associated with the residual phenolic compounds in starches, which are prone to oxidation, caramelization, and Maillard reaction during thermo-pressing. While all trays demonstrated high rate of biodegradation within 28 days (minimum 80.29 %), higher fiber content reduced the degradation rate due to the structural stability imparted by cellulose.

This study investigated the effects of shading during grain filling on PCs synthesis in three hull-less barley genotypes with different grain colors: yellow (DHL-180868), purple (DHL-151340), and black (DHL-191250). Field experiments were conducted over two seasons, applying shading treatments either for 15 days after heading (T1) or continuously until harvest (T2). Shading significantly reduced thousand grain weight (TGW) in the purple and black grain genotypes, while the yellow genotype remained unaffected, suggesting greater adaptability to low-solar radiation. TGW reductions reached up to 14 %, highlighting genotype-specific sensitivity to shading. Total PCs content also decreased under shading across all genotypes, with T1 and T2 having similar effects, with reductions of up to 21 %, emphasizing the critical role of early grain development in PCs synthesis. Despite this overall decline, individual compounds exhibited distinct responses. Notably, in DHL-151340, prolonged shading delayed anthocyanin synthesis resulting in higher final concentrations, exceeding unshaded levels by more than 40 %. Principal component analysis identified environmental factors as the main drivers of PCs variability, with free PCs more abundant in 2023 and bound PCs in 2024. These findings highlight the complex interplay between genotype and solar radiation availability in PCs accumulation and suggest that controlled shading could be a viable strategy to enhance specific bioactive compounds in barley.

Additionally, amaranth contains bioactive molecules, including pigments, flavonoids, and phenolic compounds, which enhance its potential in biotechnological applications. To fully leverage these properties, efficient methods for assessing and comparing the diversity of amaranth are essential. This study evaluates the effectiveness of ATR-FTIR and PCA as analytical tools for distinguishing between different amaranth varieties. A multivariate approach was employed to analyze the leaves, stems, and roots of three <em>Amaranthus hypochondriacus</em> varieties, integrating morphological, phytochemical, and spectroscopic assessments. Significant differences were observed among the analyzed amaranth varieties, primarily due to variations in leaf morphology and pigmentation patterns. Pigment concentration was influenced by cultivation methods. The differentiation between varieties was associated with bands at 900 and 1500 cm⁻¹. The PCA analysis of leaf samples revealed a distinct clustering pattern, indicating that the vibrations associated with functional groups in leaf samples were sufficient for identifying varieties of amaranth. The findings showed that chemometric analysis based on PCA applied to ATR-FTIR data allows for precise differentiation between varieties and tissues, reinforcing its synergy with morphological assessments. This validates infrared spectroscopy as a sophisticated, efficient, and non-destructive tool marks a significant advancement in the characterization of plant varieties.</div></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"23 ","pages":"Article 102213"},"PeriodicalIF":6.2,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144738308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
