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.

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.

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.

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.

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.
