Abstract

The paper presents the level of lead in the liver, gizzard, breast muscles and humerus of game birds, shot during the hunting season of 2016 - 2017 in Bulgaria. In quail gizzards (n=10) radiographic examination showed ingested pellets. In turtle doves (n=10), lead levels in the liver had higher values of 2,501 ± 1,404 mg/kg, compared to the maximum levels of <2 mg/kg. The content of lead in the humerus of partridges (n=10) showed a very high concentrations of 54,241 ± 36,731 mg/kg compared to the base level of 10<20 mg/kg. The high levels of lead in the tissues of the game birds, induced by lead shot exposure, are a significant risk to predators and scavengers.

Abstract

The present investigation aimed to understand the effects of dressing fertilizers and different nitrogen (N) doses on yield and nutrient uptake of chickpea (Cicer arietinum L.) plant. The study has been carried out with three repetitions under the greenhouse conditions. Nitrogen doses were; 0 kg N ha-1, 30 kg N ha-1, 60 kg N ha-1, 90 kg N ha-1 and 120 kg N ha-1 (in CaNO3.4H2O form) and dressing fertilizers were applied as 40 kg N ha-1. The results indicated that the dressing fertilizer application significantly increased average shoot dry weight with 8.18 g poƒ-1. Also, N (2.88 % N), P (0.40 % P), K (3.90 % K) and Fe (114.2 mg kg-1) concentrations increased with dressing fertilizer application of chickpea plant as compared to without dressing fertilizer application. However, dressing fertilizer application did not affect Mg, Zn, Mn and Cu concentrations of chickpea plant. Generally, in this study dressing fertilizer application increased yield and some macro and microelements concentrations of chickpea plant.

Abstract

Rosa canina L. fruit have been used internally as tea for treatment of viral infections and disorders of the kidneys and urinary tract. Also, it was reported that the R. canina fruit, with its high ascorbic acid, phenolics and flavonoids contents, have antioxidant, antimutagenic and anticarcinogenic effects. Antioxidants neutralize free radicals, which cause oxidative damage to lipids, proteins, and nucleic acids and thus protect the organism. Research studies conducted on this topic have shown that natural antioxidants are involved in protection against many diseases: cancer, cardiovascular diseases and osteoporosis. Different processing and storage methods of the fruit could affect the bioactive nutrients while preserving the antioxidant capacity of them is very important. The aim of this study was to evaluate the effect of storage in a dry or frozen state on the antioxidants content of R. canina fruit. The evaluation involved determination of carotenes, ascorbic acid and total polyphenols using spectrophotometrically methods. Analysis performed on the R. canina fruit showed significant changes in the antioxidants content in fresh, dried and frozen fruit during storage.

Abstract

Jerusalem artichoke tubers (Helianthus tuberosus) are distinguished by their protein, minerals (potassium, calcium, magnesium, iron, etc.) and inulin content. Inulin can be used in the diet of diabetics as a substitute of sugar, without having an impact on blood glucose. At the same time, an international study had shown that due to their inulin content, regular consumption of Jerusalem artichoke tubers can help to prevent type 2 diabetes. In this paper are presented the results of the researches performed to achieve a functional ingredient (powder) with high nutritional value by processing of Jerusalem artichoke tubers. Thus, the Jerusalem artichoke tubers (Red Jerusalem artichoke and White Jerusalem artichoke varieties) were subjected to a convective drying process at 50°C, to protect bioactive components (vitamins, phenolic compounds, etc.) to a moisture content that allow their milling and turning them into powder and, at the same time, their stability in terms of quality. The achieved functional ingredient was evaluated sensory, physicchemically and microbiologically. The powder obtained from Jerusalem artichoke tubers is characterized by their inulin-type fructans (51.60... 57.45%), crude fiber (6.85...8.27%), total polyphenols (18.51... 44.03 mg GAE/g), proteins (8.75...9.26%), iron (12.45...13.88 mg/100g), potassium (1905.44...2100.35 mg/100g), calcium (50.21...57.45mg/100g), magnesium (84.55...89.95mg/100g) and phosphorus content (300.12...345.35 mg/100g). At the same time, powder achieved from Jerusalem artichoke tubers has antioxidant potential. Due to its complex biochemical composition, the functional ingredient achieved from Jerusalem artichoke tubers can be used to fortify food and also as a sweetening agent for products destined to diabetics.

Abstract

Sunflower (Helianthus annuus L.) is one of the most important oil crop in the world with a harvested area in 2016 which was 3.9 times more than in 1961. The almost continuous increase of the harvested area at world level is due to the sunflower crop advantages for the farmers and to the increased yielding capacity and oil content in the seeds, all these associated with an increased demand on the market for the sunflower oil. The high yielding capacity associated with high oil content in the seeds is due to the remarkable achievements realized through the breeding programs performed at sunflower crop in the last century. These achievements are related especially to the creation of the high-yielding F1 hybrids with excellent performances. The aim of the present paper is to make an analysis and to give an insight into the situation, evolution, and historical milestones regarding the sunflower varieties and hybrids registered for cultivation in Romania in the last century. In this respect, there were analyzed different informational sources during the last century with respect to the sunflower crop in Romania, but especially the whole collection of the Romanian Official Catalogues of the Varieties of Plant Species. The official journey in Romania of the sunflower as an oil crop started in 1910 and has registered up to present a spectacularly evolution both in terms of cultivated area and varieties and hybrids cultivated.

Abstract

Water is a social requirement and an important factor in the ecological balance. Water from wells is good for direct consumption if the soil is not contaminated. The quality of drinking water is regulated by Law no. 458/2002 (transposing the Directive 98/83/EC on the quality of drinking water). The aim of this paper was to assess the physicochemical qualities of groundwaters from Brestea village, commune Denta, Timis County. The water samples were taken in 2015 from 10 functional wells. For the source whose physical and chemical parameters have exceeded the limit values, the monthly monitoring of the water quality (microbiological and physico-chemical properties) has been performed for 2 years. At the same time, the pH of the soil near the water sources was also measured. The results highlighted a good connection between the microorganisms from water and the nitrite, nitrate and ammonium content of water. The information can be further used to identify and eliminate the specific pollutants, areas and pollution sources.
