Ethanol solutions of essential oils obtained from Athmanta haynaldii and Myristica fragrans were tested for their toxicity and antifeedant activity against the second instar gypsy moth larvae in the laboratory bioassay. Both isolated oils were subjected to gas chromatography analysis in order to determine their chemical constitutions. Tested oils showed low to moderate larvicidal effect in both residual toxicity test and in chronic larval mortality bioassay. However, antifeedant index achieved by application of tested solutions in feeding choice assay was significantly higher in comparison to control, and almost same as one provided with botanical standard. Low toxic and high antifeedant properties (AF index 85-90%) make these essential oils suitable for integrated pest management programs. Special attention should be paid to further investigation of endemic and rare A. haynalidii in the terms its cultivation and usage of its unique set of biologically active compounds. © 2012 Elsevier B.V.

A wide range of 'Oblačinska' sour cherry germplasm was collected from the most important growing regions in Serbia. Twenty nine variables were recorded in 41 accessions to determine the overall degree of polymorphism and to detect similarities among genotypes. The highest degree of variability was observed in traits related to number and composition of fruiting twigs, fruit set and yield. The majority of significant correlation coefficients were found in the characteristics representing fruit and leaf size. Principal component analysis (PCA) makes the phenotypical diversity determination and separation of similar genotypes possible. Variables with high discriminating values were those related to fruit and leaf size, yield efficiency, blooming time and flowering density. Based on the results from this study, the genotypes XI/3 and II/10 can be recommended for cultivation. The clonal selection and conservation of the highly diverse autochthonous population of sour cherry are also recommended. © 2010 Elsevier B.V.

Fish meal and fish oil represent main protein and lipid sources in fish feed, but there is a growing need for sustainable alternatives to these ingredients. In this study, four isolipid extruded diets for carp (. Cyprinus carpio L.) were used: ROHP (rapeseed oil-high protein), FOHP (fish oil-high protein); ROLP (rapeseed oil-low protein) and FOLP (fish oil-low protein). The trial lasted 75 days. No statistically significant effect of oil source or protein level or interactions of these factors was observed in final body weight, growth parameters or in feed conversion ratio. Protein sparing effect and omega-3 sparing effect were observed in the present study. The results of this experiment showed no negative effects on growth parameters, or major detrimental effects on fatty acid composition of muscle tissue in common carp when fish fed with diets supplemented with rapeseed oil (RO). Furthermore, an enhanced protein sparing effect was observed, when fish fed with lower protein diets, but significant accumulation of crude lipid was observed as a result of lowering protein level. The results of this study showed that diets supplemented with rapeseed oil can be used successfully in common carp cage production. © 2014 Elsevier Inc.

The trial was set up in field conditions during 2003/04-2005/06 with seven different treatments of seed protection and three winter wheat varieties. According to analysis of variance, the years and the interactions between variety x years, variety x treatment, year x treatment and variety x year x treatment had highly significant effects on test weight. Variety Vizija had significantly lower test weight in comparison with Pobeda and PKB-Christina varieties. Highly significant difference was proven between control and treated variants. Test weight in plots where the electronic way of protection using plasma electrons was used was at the level of control and significantly lower in comparison to fungicidal protection, in tested varieties.

The researches were done in the field conditions using three winter wheat varieties and seven ways of seed protection. Varieties are different according to the tillering type, stalk height, leaves' position, length of growing season, genetic potential for yield and grain quality, and they are PKB-Kristina, Pobeda and Vizija. Variety trial was set up in test field of "Tamis" Institute (2003/04 - 2005/06) in Pancevo using split-plot method with four protection variants with fungicide, plus electronic protection of plasma electrons with positive and negative control. It was determined that the way of seed protection was the factor that has a significant impact on the grain yield. Vizija variety had lower grain yield (6.59 t/ha{cyrillic}) than Pobeda variety (7.02 t/ha) and PKB-Kristina variety (7.07 t/ ha). The difference is highly significant. Comparing the yield from the aspect of the applied way of protection, highly significant difference between the control (6.61 t/ha) and variants, being treated by diviconazole, difeconazole, carboxine + tiran and tebuconazole + triazoxine, was proven. Significant difference was not established between variants being treated by diviconazole and difeconazole, whereas significantly lower yield than they had, had the treatment with ed carboxine + tiran and tebuconazole + triazoxine. Significant difference was not establish between them. Treatment with electronic way of protection of plasma electrons showed significantly lower grain yield than the protection with fungicides and it is controlled. In the case of all tested variants, where seed protection was done, significant difference concerning grain yield in comparison to control, was established. Highly significant difference was established between the years when the research was done as well as variety x year interaction.

The aim of research was to establish the influence of seed size on grain yield of three wheat varieties. A trial was set up using split-plot method in four replications in Pancevo in the period 2004-2006. Seed was divided according to the size in five fractions: 1.8, 2.0, 2.2, 2.5 and 2.8 mm. There were very significant differences in wheat grain yield due to years, varieties, seed size and years x seed size interaction. The highest average wheat grain yield of 6.57 t/ha was recorded in 2005, significantly higher than the yield in 2004 and 2006. The yield of Pobeda and PKB-Christina varieties was significantly higher than the one of Vizija variety (at P<5%). For significance level of 1%, there were no differences in grain yield between the tested varieties. The highest wheat grain yield of 6.88 t/ha and 6.54 t/ha was achieved in the case of 2.5 and 2.2 mm-seed sizes. Wheat grain yields obtained in the cases of the other seed fractions (1.8, 2.0 and 2.8 mm) were significantly lower. The highest wheat grain yield was achieved in 2005 in the case of 2.5 mm-seed size, significantly higher than all the other values of years x seed size interaction.

Nitrogen use efficiency parameters of twelve bread wheat cultivars were studied in nine environments comprised of three nitrogen applications tested over three years. An environment-by-trait association biplot and a trait-association by environment biplot were applied to understand environmental effects on these traits and relationships among them. The following trait associations were relatively stable across environments: negative associations of straw nitrogen content vs. nitrogen remobilization efficiency, straw nitrogen content vs. nitrogen harvest index and a positive association of nitrogen remobilization efficiency vs. nitrogen harvest index. The selection of genotypes with a high nitrogen harvest index and nitrogen remobilization efficiency could be used in the development of cultivars with desired nitrogen use efficiency. A low straw nitrogen content can also be used as a reliable and cost-effective indicator in the selection of genotypes with high nitrogen use efficiency. © 2010 Akadémiai Kiadó.

This study reports data on traditional phytotherapy regarding wild flora in the Deliblato Sands, the Special Nature Reserve located in Serbia, South East Europe. Though interviewing local people on identification of plants, plant parts used, methods of remedy preparation and administration, 231 wild plant species of medicinal importance from 172 genera and 62 families, and 101 original preparations were documented. A high degree of consensus (ICF > 0.45) was observed among informants when treating the most common ailments: wound infections, insect/snake bites, blood purification, menstrual and nervous disorders, bronchial/lung catarrhs, cough, cardiac disorders, constipation, diarrhea, urinary infections, rheuma. Most of medicinal plants listed by informants were available, while seven of them were classified as endangered and entered into the system of statutory protection. This study confirmed the extensive indigenous knowledge on medicinal plants, and pointed to some ways of usage that have not been documented in the literature.

The effect of storage was studied on grain metabolites, functional properties and digestibility of three oat cultivars selected in Serbia - Dunav, Vrbas and NS Tara. During the 12 and 24. months of storage, there was a decrease on average in total proteins (10.98% and 15.95%) lipids (7.55% and 11.82%), crude cellulose (6.65% and 14.77%) and starch concentration (6.48% and 9.48%), and an increase in total ash concentration (4.8% and 9%) and dry matter (4.53% and 5.92%). Storage period caused a decrease in β-glucan concentration. The concentration of total phenolics (28.79-41.19%) and caffeic acid markedly decreased after 24. months of storage. The storage period significantly influenced the ferric reducing ability (FRAP) (36.34-43.12%) and the DPPH radical scavenging activity (76.92-237.14%). Organic matter digestibility of oat grains was slightly changed, but remained over 70%. Based on the present study, oat grain should not be stored longer than 12. months since phenolics contribute markedly to health promoting effect of oats. © 2014 Elsevier Ltd.

In order to determine the overall degree of polymorphism and detect similarities among genotypes, 19 almond [Prunus dulcis (Mill.) D.A.Webb] genotypes were studied. Variation in traits related to phenology, morphology, and fruit quality was observed, and the results indicated a high morphological diversity of almond genotypes. The majority of important correlations were determined among the traits representing nut size (nut width, nut length, nut thickness, and nut weight) and leaf size (leaf length, leaf width, and leaf area). The lack of correlation between kernel size and chemical compounds enables the creation of a new almond cultivar with large kernels and improved quality. Principal component analysis showed considerable phenotypic diversity among the almond genotypes. Parameters with high discriminating values were those related to nut, kernel, and leaf size; ripening time; and tree habit. Genotypes B/04, 1/03, and 28/03 were singled out as the most promising for breeding and commercial growing. © TÜBITAK.
