The experimental samples were prepared by the SPE technique and analyzed in terms of acrylamide content by GC-MS/MS. Results showed that the acrylamide content is significantly affected by the size of the potato slices and by the frying times: for 6 min of frying it varied from 222.90 µg/kg (7 mm) to 217.81 µg/kg (9 mm) and 192.36 µg/kg (11 mm), respectively; for 8 min of frying it ranged from: 842.44 µg/kg (7 mm) to 416.23 µg/kg (9 mm) and 343.19 µg/kg (11 mm); for 11 min of frying it was between 2636.06 µg/kg (7 mm), 1114.41 µg/kg (9 mm) and 906.70 µg/kg (11 mm), respectively. A reduction in the acrylamide level was obtained by about 14%, 59%, 66% for 6, 8, 11 min of frying at the size of 11 mm, compared to those divided at the size of 7 mm. The acrylamide formation in French fries was significantly reduced with larger the size of the potato slices and with shorter periods of frying. When increasing the potato slice size, positive linear correlations were obtained between the acrylamide level and the color parameters a* and b* (R² = 0.54 - 0.99) and negative linear correlations with the color parameter L* (R² = 0.684- 0.998).","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114260592","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}

However, as with other plant species, annual grass plants are adversely affected by soil salinity. The aim of present study; determination of the salt tolerance of annual grass cultivars in vitro. In the study, 25 registered grass varieties were used as material. Salt concentrations of 150 mM NaCl were applied to determine the response of annual grass varieties to salt stress. Root length, shoot length, root-shoot fresh weight and root-shoot dry weight were examined in in vitro salt testing and the lowest values in the control group in terms of these properties were obtained from Efe and Vallivert cultivars, while the highest value was obtained from Medoacus and Trinova cultivars. In salt application, the lowest value was obtained from Tornado, Vallivert, Venus varieties, while the highest value was obtained from Medoacus and Trinova varieties. In addition, the variation obtained among the annual grass varieties used in the study can be used both in the grass aplication and in breeding programs.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114367926","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}

Consequently, the results of this survey allowed us to group organic agriculture into three types on the basis of structural and operational criteria: the first type is certified, often modern, small in number, following international specifications, and frequently located in the East; the second one is mixed, respecting the standards of organic agriculture, not certified but large in size; as for the third type, it is traditional, in other words natural, and more widespread. Subsequently, organic agriculture in Algeria is limited in terms of space and number, whilst the majority of practices have shown to be of traditional nature, poorly supervised and controlled due to the technical, socio-economic and agricultural policy constraints.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"210 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131686774","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}

It was aimed to determine of effect of iron, boron and zinc applications on yield and quality traits in some soybean cultivars. The experiment was carried out as a split plot design based on RCBD with three replications, in which cultivars constituted the main plot with three cultivars (Arısoy, Safir and Bravo), and micronutrients and their combinations constituted the sub-plot (control, Fe, B, Zn, Fe+B, Fe+Zn, B+Zn and Fe+B+Zn). The micronutrients were applied to the plant by foliar spraying in the V3-V5 period. In the study plant height, first pod height, pod number per plant, seed number per pod, 100 seed weight, seed yield, oil content and crude protein content were investigated. The results showed that foliar micronutrients significantly increased the values for all traits. According to research findings, seed yield values of cultivars changed between 304.93-382.62 kg da-1, oil content values 12.51-17.16% and crude protein content values 37.82-42.30% and showed a wide variation. In terms of cultivar x micronutrient interaction, the highest seed yield was obtained from the Fe+B, Fe+Zn and Fe+B+Zn applications in Safir variety (395.01, 393.55 and 396.42 kg da-1, respectively). The crude protein content, which is the most important character in soybean, varied between 36.79-43.14%, but this difference was not found to be statistically significant for interaction.

Honey samples vary in quality according to various factors, such as climate diversity, geographical characteristics, floral supply period, and packaging and storage conditions, which can compromise the quality of the hive's final product. The assessment of honey quality is a major concern that has gained interest internationally because honey has always been subjected to various fraudulent practices which become more sophisticated in the present day. Consumers, beekeepers, and regulatory bodies are interested to have reliable analytical tools and information to allow the detection of adulterated honey. The UV-VIS spectroscopy and FTIR spectroscopy techniques are two analytical methods used to analyze the honey quality nowadays, with hydroxymethylfurfural being used as a standard for testing honey's freshness. The present study was conducted to assess the quality of some floral honey samples (rapeseed, acacia, and polyfloral honey) produced in Argeș, Călărași, Giurgiu, and Teleorman counties from the south of Romania. Differences between honey botanical and geographical origins were analyzed and highlighted with One-way ANOVA (p˂0.05), followed by Duncan`s Multiple Range Test.

Olive oil is considered more important due to its nutritional and health advantages. The olive tree can adapt to adverse soil conditions because it is not very selective in terms of soil requirements. Turkey has a very rich diversity because it is located in the homeland of olives and has been cultivated for many years. There are olive populations that show variation in tree form, leaf and fruit characteristics in different regions of Turkey. Identifying and revealing the characteristics of plants in these populations is important for their evaluation. In this study, some morphological features were determined in olive populations in Kahramanmaraş region, which has a significant diversity. Within the olive populations, seed and leaf characteristics were revealed in 44 genotypes that were visually different and over 50 years of age. Statistical differences were found between genotypes in terms of all parameters studied. The kernel weights of the genotypes varied between 0.76-0.38 g. Kernel length and width values were determined as 16.03-12.21 mm and 10.07-8.01 mm, respectively. The highest leaf length of the genotypes was 7.42 cm and the lowest 5.70 cm. Leaf widths were determined as 15.82-8.49 mm. The results revealed that there is a significant olive diversity in Kahramanmaraş region.
