Genetic Variability of Yield and Its Components in Winter Forage Pea Cultivars

The genus Pisum (peas) is rich in variability of morphological traits. It provides an excellent basis for breeding, but is also one of the reasons for the still undefined status of Pisum taxons (Mihailović et al., 2004a). The majority of forage pea cultivars used belongs to subspecies sativum and variety arvense (Maxted & Ambrose, 2000). The objective of our study was to determine genetic variability of yield and its components in six winter forage pea cultivars of different origin and to evaluate their breeding potential

Changes in Crude Protein Content with Advancing Maturity in Lucerne

The main determinants of the quality of lucerne forage are digestibility and protein content (Julier et al., 2001) as well as crude fibre content. In the early vegetative phases, the crude protein content of the leaves and stems is the highest and crude fibre content the lowest (Katic et al., 2003). The aim of this study was to determine the rate of change in crude protein levels at different stages of growth and development

Agronomic Characteristics of Novi Sad Winter Vetch Cultivars

Genus Vicia. contains important annual food and forage species such as field bean, V. faba., narbon vetch, V. narbonensis, and common vetch, V. sativa (Maxted, 1995), while Hungarian V. pannonica Crantz and hairy vetch V. villosa also play an important role in the Balkans. Winter vetches are excellent forage catch crops useful for sustainable agriculture and organic farming (Ċupina et al., 2004). Our study was aimed at determining the agronomic characteristics of the winter vetch cultivars developed in Novi Sad, assessing thus their ability for successful growing in the prevailing conditions of Serbia and Montenegro

MEDICINAL PROPERTIES OF BUCKWHEAT PRODUCTS AND HONEY IN COMPLIANCE WITH FOOD SAFETY REGULATORY REQUIREMENTS

Buckwheat (Fagopyrum esculentum Moench) is a gluten-free pseudo-cereal and honey plant. Buckwheat grain yields vary greatly and depend on the genotype, agro-ecological conditions of production and harvesting method. The grain yield of the 'Novosadska' variety variеs 1.5-3 t ha-1and the honey yield amounts and more than 300 kg ha-1. Buckwheat grain contains: carbohydrates, proteins, fats, organic acids and rutin (quercetin-3-rutinosid), minerals (potassium, phosphorus, calcium, magnesium, sodium, iodine, zinc, bromine and iron), vitamins (D2-ergokalciferol, D3-holekalciferol, P-bioflavonoids, vitamins group B: B1-Thiamine, B2-Riboflavin, B3-niacin, B4-Choline, B5-Pantothenic acid, B6-Piridoxin, B9-Folate; and vitamin E-Tocopherols. 'Novosadska' buckwheat contains the highest level of phenolic acids, proanthocyanidins, flavones and flavonols. Buckwheat honey is dark color, which it gets from polyphenols. Polyphenols is antioxidants, organic compounds which affect the quality of food, especially the color and taste. In accordance with the law on food safety, the interests of consumers must be ensured the highest level of protection. Phenolic antioxidants from honey are bioavailable and increase the antioxidant activity of plasma. Buckwheat honey has a beneficial effect on bronchitis and cough, hypertension, arteriosclerosis, of heart disease, liver and intestinal diseases and has antibacterial effects

Mechanisms of injury of pedestrians in road traffic accidents

Determination of direction of car impact on pedestrian is complex interdisciplinary biomechanical analysis, which sintetize the work of legal medicine and traffic engineering professions. Injury characteristics depends on constitution and position of pedestrian, and type of passenger car. There are different mechanisms of injury arising from sum of effect of complex mechanical forces, from motion and impact on human body. Results are showing that new generation car, with aerodinamic wedge front, favorize occurrence of hyperextensive injuries, while speed presents dominant factor of intensity of injuries. In modern traffic conditions, we found multiple reduction of number of deaths of pedestrians in road traffic accidents

Variability of sesquiterpenes in essential oils of the species Teucrium montanum l.

Cilj prikazanog istraživanja je utvrđivanje kvalitativne varijabilnosti i relativne zastupljenosti seskviterpenskih ugljovodonika u uzorcima vrste Teucrium montanum L. prikupljenih sa dva različita tipa podloge. Četiri uzorka etarskih ulja sa serpentinita i četiri sa krečnjaka dobijeno je metodom hidrodestilacije od nadzemnih biljnih delova. Na osnovu rezultata, pokazano je da populacije sa serpentinitskih staništa sintetišu 2 puta više seskviterpena nego sa krečnjačkih, dok je jedinjenje 6-epi-β-kubeben detektovan samo u populacijama sa krečnjaka. Edafske karakteristike staništa utiču na kvalitativni sastav i relativnu zastupljenost seskviterpena u etarskim uljima što ima značajnu primenu u biotehnologiji.The aim of this study is to determine the qualitative variability and relative presence of sesquiterpene hydrocarbons in essential oils samples of Teucrium montanum L. collected from two different substrate types. Four samples of essential oils from serpentinite and four from calcareous were obtained by the method of hydrodistillation from aboveground plant parts. Based on the results, it was shown that populations from serpentinite habitats synthesize 2 times more sesquiterpenes than from calcareous ones, while the compound 6-epi-β-cubeben was detected only in populations from calcareous. Edaphic characteristics of habitats affect the qualitative composition and relative presence of sesquiterpenes in essential oils, which has a significant application in biotechnology

Evidence for strong electron-phonon coupling and polarons in the optical response of La_{2-x}Sr_xCuO_4

The normal state optical response of La_{2-x}Sr_xCuO_4 is found to be consistent with a simple multi-component model, based on free carriers with strong electron-phonon interaction, localized polaronic states near 0.15 eV and a mid-infrared band at 0.5 eV. Normal state reflectance and absorbance of La_{1.83}Sr_{0.17}CuO_4 are investigated and their temperature dependence is explained. Both, the ac and dc response are recovered and the quasi-linear behavior of the optical scattering rate up to 3000- 4000 cm^{-1} is found to be consistent with strong electron-phonon interaction, which also accounts for the value of T_c. Although not strictly applicable in the superconducting state, our simple model accounts for the observed penetration depth and the optical response below T_c can be recovered by introducing a small amount of additional carriers. Our findings suggest that the optical response of La_{2-x}Sr_xCuO_4 could be explained both, in the normal and superconducting state, by a simple multi-fluid model with strong electron-phonon interaction if the gap symmetry and the temperature dependence of the 0.5 eV mid-infrared band are adequately taken into account.Comment: 22 pages, REVTeX, 12 figures in ps-fil
