The aim of the study was to investigate the chemical composition and thermooxidative stability of red palm olein, rapeseed oil and their mixtures during deep-frying of French fries. Analysis of fatty acids composition and basic parameters of fresh oils (acid number, peroxide value, polar compounds content, induction time) were performed. During frying, changes in acid number, polar compounds in oils as well as consumers’ acceptance of the fries fried in these oils were investigated. During the 32-hour of frying, the lowest chemical changes occurred in palm olein, what was confirmed by low acid values (0.99 mg KOH/g) and low polar content (14.4%). At the end of the experiment, the oil mixture had the highest polar fraction value of 25.0%. In the opinion of consumers, fries fried in rapeseed oil were “the best”, while French fries fried on palm oil were considered “artificial”, “chemical” and “disgusting”. The reason for this opinion was the addition of β-carotene to this oil. On the other hand β-carotene from palm olein had a great positive effect on the colour of the fries, but at the same time had a negative effect on the taste.","PeriodicalId":56276,"journal":{"name":"Journal of Applied Botany and Food Quality-Angewandte Botanik","volume":"91 1","pages":"103-108"},"PeriodicalIF":1.2,"publicationDate":"2018-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47780502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BAP best improved growth performance of moringa plants, improving shoot length, root length, number of leaves and photosynthetic pigments, followed by MLE at 75% field capacity, while moringa plants showed reduced growth at 40% field capacity which was increased by BAP and MLE foliar application. Maximum contents of gallic acid, p-coumaric acid and sinapic acid were found in moringa leaves when the plants were sprayed with ascorbic acid while p-hydroxybenzoic acid and caffeic acid were maximally increased under 75% field capacity when the plants were subjected to BAP followed by MLE. The lowest and highest crude protein, calcium, potassium, magnesium, and phosphorous contents were recorded under 40 and 75% field capacity, with MLE impro-ving these contents under both conditions. It can safely be concluded that moringa plants showed retarded growth under 100 and 40% field capacity, and that the effects of deficit in nutritional quality were mitigated by applying BAP and MLE.

Our objective was to evaluate changes in concentration of main pineapple bioactives, their contribution to total antioxidant capacity and enzyme activities of phenylalanine ammonia lyase (PAL), polyphenol oxidase (PPO) and peroxidase (POD) during pineapple ripening. Fruits were grouped into four ripening stages (RS) according to their weight, size and percentage of yellow skin color (RS1: 100% green, RS2: up to 30% yellow, RS3: 30% - 75% yellow, RS4: 75% - 100% yellow). Vitamin C content initially increased, and decreased at RS4; β-carotene, phenolics and antioxidant capacity increased gradually. Phenolics contributed over 40% of antioxidant capacity, followed by vitamin C and β-carotene. Major phenolic compounds identified were gallic acid, catechin and epicatechin. PAL and POD activity increased with ripening and correlated with concentration of phenolics. No PPO activity was quantified. We concluded that ripening of pineapple cv Esmeralda alters the concentration of bioactive compounds. Phenolic compounds, particularly gallic acid, exert the most antioxidant capacity during all RS, even if other compounds have higher concentrations.","PeriodicalId":56276,"journal":{"name":"Journal of Applied Botany and Food Quality-Angewandte Botanik","volume":"91 1","pages":"61-68"},"PeriodicalIF":1.2,"publicationDate":"2018-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44791089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The abundance and diversity of arbuscular mycorrhizal fungi (AMF) might also be influenced, but so far effects on AMF by permanent vege-tation cover (= no-tillage systems) or repeated chiseling and rotary-tillaging have rarely been compared in vineyards. The objective of this on-farm study was to determine AMF species richness and diversity in two adjacent vineyards in Palatinate (SW Germany). In both vineyards, grown on fertile Luvisols, the var. “Pinot Gris” was grown for 39 years, but with different soil cultivation and different fertilization strategies. In one vineyard, soil was maintained periodically without vegetation by passing rotatory cultivator and chiseling between the grapevine rows (‘inter-rows’) several times per year, preferably during spring and summer and in dependency of rainfall and ‘weed’ growth, and fertilization was mainly by organic fertilizers in the last ten years before soil sampling. In the other vineyard, a permanent vegetation has been established since planting, dominated by Lolium perenne, and mineral fertilizers were exclusively applied. Despite of similar high nutrient availability in both soils, in particular of phosphorus, astonishing high AMF species richness and diversity were found in both vineyards. In the no-tillage inter-rows, 34 AMF species were found, with a species composition typically for Central European permanent grasslands (Shannon diversity index 2.45). In the tillage system 24 AMF species were found with a composition as known for extensively used, cultivated Central European croplands (diversity index 2.26). We conclude that above all soil cultivation has affected AMF diversity in these Central European vineyards, while the level and type of fertilization affected the AMF communities only on a minor level.","PeriodicalId":56276,"journal":{"name":"Journal of Applied Botany and Food Quality-Angewandte Botanik","volume":"91 1","pages":"56-60"},"PeriodicalIF":1.2,"publicationDate":"2018-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45780300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The deduced amino acid sequence of RcMF3′H1 contained the proline-rich “hinge” region, P450 consensus heme-binding domain, and F3′H-specific motifs. Phylogenetic analysis revealed that RcMF3′H1 was clustered into the same subgroup as other plant F3′Hs. In addition, expression analysis by quantitative real-time PCR revealed the involvement of RcMF3′H1 in methyl jasmonate-mediated anthocyanin biosynthesis. Furthermore, the ability of the RcMF3′H1 gene to complement the Arabidopsis transparent testa 7-1 mutant suggested that RcMF3′H1 encodes the functional F3′H enzyme involved in anthocyanin biosynthesis.

Nitric oxide (NO) is considered as a functional molecule in alleviating the oxidative damage of salinity to plants through modulating antioxidant metabolism. In the present study, effects of sodium nitroprusside (SNP), a NO donor, on induction of callus and seed germination, and antioxidant capacity of Hyoscyamus niger seedlings were studied under 0, 50, 100 and 150 mM NaCl stress. NO stimulated the germination of NaCl-treated seeds. NaCl treatment significantly induced accumulation of H2O2 and thiobarbituric acid-reactive substances (TBARS) in Hyoscyamus niger, and application of 100 μM SNP stimulated ROS-scavenging enzymes and increased scavenging activity (DPPH), hydroxyl radical (OH•) scavenging activity and chelating activity of ferrous ions, resulting in lower lipid peroxidation induced by NaCl stress. Therefore, it can be concluded that the increased antioxidant capacity by NO might be responsible for its function in alleviating the inhibition of Hyoscyamus niger growth and cell damage by salt stress. Also the effect of SNP on the induction of callus of Hyoscyamus niger was investigated. Callus fresh weight increased significantly in the combined effect of 50 μM SNP with other plant growth regulators (PGR) compared to control. It is evident that SNP has a direct effect on the induction of callus by interacting with cytokinins and auxins.","PeriodicalId":56276,"journal":{"name":"Journal of Applied Botany and Food Quality-Angewandte Botanik","volume":"91 1","pages":"24-32"},"PeriodicalIF":1.2,"publicationDate":"2018-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45160295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
