Delay in the critical time for weed removal in imidazolinone-resistant sunflower (Helianthus annuus) caused by application of pre-emergence herbicide
(Taylor & Francis Ltd, Abingdon, 2013)
The critical time for weed removal (CTWR) is a period in the crop growth cycle when weed control must be initiated to prevent yield losses. Knowing the CTWR is useful for making decisions about the timing of weed control ...
Determination of Conyza canadensis Levels of Sensitivity to Glyphosate Trimesium Sulphosate
(International Journal of Agriculture and Biology, 2013)
Changes in leaf anatomy were examined in two S. African populations of Conyza canadensis of which one was presumed to be resistant (CCPR) and the other susceptible (CCS) to glyphosate. Glyphosate was applied to plants, ...
The Melliferous Potential of Forest and Meadow Plant Communities on Mount Tara (Serbia)
(Oxford Univ Press Inc, Cary, 2013)
The apiflora of 34 forest and meadow plant communities in Tara National Park was studied with the aim of assessing their melliferous potential and their contribution to bee pasture during the vegetation period. The melliferous ...
Spatial modelling of soil erosion potential in a mountainous watershed of South-eastern Serbia
(Springer, New York, 2013)
This work aims at the assessment of soil erosion rate and its spatial distribution in hilly mountainous Nisava River Basin (South-eastern Serbia) with a surface area of approximately 2,848 km(2). The study was conducted ...
Fruit quality of red raspberry cultivars and selections grown in Western Serbia
(Czech Academy Agricultural Sciences, Prague, 2013)
Biological and chemical properties of cv. Willamette were contrasted with those of cvs Tulameen, Latham, Meeker and K81-6 grown under agro-environmental conditions of Western Serbia. The following parameters were examined: ...
Structural properties of composites of polyvinylidene fluoride and mechanically activated BaTiO3 particles
(IOP Publishing Ltd, Bristol, 2013)
Nanocomposites of electroactive ceramics and ferroelectric polymers exploit favorable features of the matrix polymer and the nanostructured filler to produce new functional materials for pressure and IR sensors. In this ...
A chemometrics as a powerful tool in the elucidation of the role of metals in the biosynthesis of volatile organic compounds in Hungarian thyme samples
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2013)
The volatile fraction of the leaves of Thymus pannonicus All. (Lamiaceae) was analyzed by headspace extraction followed by GC-FID and GC-MS analysis. The different headspace profiles were recognized, with citral and with ...
Electroporation Enhances the Metabolic Activity of Lactobacillus plantarum 564
(University of Zagreb, 2013)
The exposure of bacterial cells to pulsed electric fields (PEF) leads to the reversible formation of pores in the cell membrane if an applied energy is below the critical level. Therefore, the effect of electric field ...
Melliferous potential of Brassica napus L. subsp napus (Cruciferae)
(Springer, Dordrecht, 2013)
Morphophysiological characteristics of oilseed rape flowers, such as features of the nectaries, nectar production, and observations on honey bee visits and honey and seed yield were studied with the aim to evaluate the ...
Influence of the chemical structure of poly(urea-urethane-siloxane)s on their morphological, surface and thermal properties
(Springer, New York, 2013)
Segmented poly(urethane-urea-siloxane)s (PUUS) were synthesized using 4,4'-methylenediphenyl diisocyanate (MDI) and ethylene diamine (ED) as the hard segment components and hydroxypropyl-terminated poly(dimethylsiloxane) ...
