Research About Improvement the Aromatique Grapevine by Selection Clonale in the Vineyard Dealu Bujorului
The research in this paper aims the quality producţion and uvologic values of two elites clonal ‘Muscat Ottonel’ 35-21, ‘Şarbă 25-45’ and two varieties ‘Muscat Ottonel’, ‘Şarbă’ for  aromatic white wines  cultivated in SCDVV Bujoru. The highest weight of a grape was recorded in the ‘Şarbă 25-45’ (183 g) and the lowest was recorded in ‘Muscat Ottonel’ (93 g). The lowest index structure was recorded in ‘Muscat Ottonel’ (27.0) and the higher was registered in ‘Muscat Ottonel 35-21’
Assessment of Trace Elements and Human Health Risk Present in Wines Obtained in the Region of Dealurile Munteniei and Dealurile Moldovei Vineyards
The primary objectives of this research were to determine the concentration of some inorganic trace components, to evaluate the concentration levels of these in Romanian wines by daily consumption of wine and the health risk of inorganic trace components intake at these rates form Romanian wine. The results indicated that the concentration levels of inorganic components in red wine decreased in the order Zn>Mn>Cr>Cu>Ni>Pb>Co>Cd, in case of white wine decreased in the order Zn>Mn>Cu>Cr>Ni>Pb>Co>Cd. Based on a 60-kilogram adult person, and moderate consumption of 200 milliliters of wine/day, the estimated daily intake of these inorganic components from wines was well below the daily allowance. The target hazard quotient suggests that the exposed humans would not experience significant health risks when ingesting these individual elements from daily consumption of 200 milliliters of Romanian wines/day
Differentiation Among Romanian Wine Regions Based on Lead Isotope Signatures
The objective of this study is to determine the Pb concentration and 206Pb/204Pb, 206Pb/207Pb, 206Pb/208Pb from several Romanian winemaking regions, in order to highlight credible geographical markers of wine origin. The Pb level concentration and the ratios of 206Pb/204Pb, 206Pb/207Pb, 206Pb/208Pb were determined in 25 white and 9 red wines using ICP-MS techniques. Based on 206Pb/207Pb isotope ratios it can be concluded that the vines grown in the Tîrnave vineyard [Blaj (1.1790 average value)], Huși vineyard [Huși (1.1958 average value wine center), Averești (1.1908 average value)] and Iași vineyard [Copou (1.1875 average value) wine center], show traces of atmospheric pollution with lead [if 206Pb/207Pb=~1.1700-1.2200 (atmospheric pollution)]. Combining the 206Pb/204Pb with 206Pb/208Pb isotopic ratio may carry out a separation on the vineyards and wine-growing centers. Based on 206Pb/204Pb, 206Pb/207Pb and 208Pb/206Pb a separation of the wine samples was possible
PHENOLIC, ANTHOCYANIN COMPOSITION AND COLOR MEASUREMENT AT RED WINES FROM DEALU BUJORULUI VINEYARD
Phenolic compounds, extractable from grape skins and seeds, have a notable influence on the sensorial properties of red wines, especially their chromatic characteristics, bitterness and astringency. The phenolic compounds, together with the aroma precursors are the main factors that affect wine quality. In this sense, the aim of our work were to (i) establishment the ecoclimatic conditions from Dealu Bujorului vineyard 2018 year of culture, and (ii) determination of phenolic maturity of the Cabernet Sauvignon, Feteasca neagra, Babeasca neagra, Merlot and Burgund varieties. In case of phenolic content, anthocyanin, hue and color intensity differed among vintages, no clear trend was evident. The lack of clear relationship between vintages is most likely the product of the complex nature of phenol composition and how it is affected by varying climatic conditions between seasons, as well as variation amongst the wines in terms of degree of agin
New Vine Varieties for High Quality White Wine Production at RDSVV Bujoru
The degree of fertility coefficient absoltul (CFA) and coefficient ratio (CFR) we can see that the highest values were obtained from the variety 'Fetească regală' (54.5 ± 1.00% fertility; 1.60 ± 1.00 coefficient absolute (CFA ) and 0.86 ± 1.00 coefficinet relative (CFR). The  analysis of physical-mechanical based on the results it can be seen that the variety 'Bujoru' showed the best values for all parameters analyzed (303.5 ± 1.0 (g) the average weight of the grape bunch, 278.07 ± 1.0 (g) weight of 100 berries; 213.66 ± 0.67 (g / L) sucrose sugar concent and 4.331 ± 1.0 (kg / comes) average coming production).Â
Investigation of the Copper Content in Vineyard Soil, Grape, Must and Wine in the Main Vineyards of Romania: a Preliminary Study
The long-term use of copper in viticulture has caused great copper accumulation in vineyard soils, resulting in negative effects on the environment through toxicity to aquatic and soil organisms. The aim of this study was to investigate the copper content in vineyard soils, grapes and wines from Dealu Bujorului, Murfatlar, Tarnave, Iasi and Ştefăneşti vineyards. The ICP-MS method was used for copper determination in vineyard soil, grape must and wine. Copper concentration in red wine samples was significantly higher than in the white wine samples. Values for Transfer Factor and Mobility Ratio indicates that Vitis vinifera L. does not allow the accumulation of copper from vineyard soil in must grape and wine. The copper concentration in grapes, must and wine has been influenced by the copper concentration in soils, by copper fungicide used to protect the vine and by other factors such as the biological specificity of cultivars during growth
Analysis and Evaluation of The Main Ecoclimatic Conditions From Romania's Vineyards
Vines act as indicators in relation ecoclimatic changes and they are particularly sensitive to temperature changes. Temperature is a limiting factor and define the distribution area for all plants. The main objective of this paper is to present the climatic conditions such as temperature, insolation, rainfall and cloudiness of Romanian main vineyards (Dealu Bujorului, Murfatlar, Târnave, IaÈ™i, ștefăneÈ™ti-ArgeÈ™i). The thermal balance with the highest values was recorded in Murfatlar vineyard having a value of 5288 (Σtg), the active thermal balance (Σta) 4815, and the useful thermal balance (Σtu) 2514. Insolation and precipitations are in normal parameters for viticulture. The highest values of the real heliothermic index (IHr), hydrothermal coefficient (CH) and wine bioclimatic index (Ibcv) were recorded in Murfatlar vineyard (IHr=4.1; CH=0.8 and Ibcv=11.4). The result show that the ecoclimatic conditions from the studied vineyards are favorable, that makes possible the production of both red and white wines of high quality in these areas
