The aim of this research was to determine ecoclimatic conditions and also to determine the phenolic maturity of Fetească neagră and Merlot from Dealu Bujorului vineyard in the conditions of the 2016 year of culture. Under the ecoclimatic conditions of 2016, the grapes entered in the ripening process prematurely, and full maturity was achieved very early. The results showed the suitability of ecoclimatic conditions and the proper growth and development of the tested varieties for obtaining wines with superior’s quality. The variation of the phenolic characteristic represents a strong marker for wines geographical traceability.

Daily consumption, wine contributes to the requirements of essential elements, such as Ca, Fe, Mn, Mo, Co, Cr, K, Ni, Se and Zn for humans. However, the presence of significant amount of heavy metal in wine may harm the health of consumers. The present work is aimed at establishing the heavy metal content in red wines from Dealu Bujorului vineyard using ICP-MS method for the determination of metals content. In this study 3 red wines obtained from ‘Băbească neagră’, ‘Negru Aromat’ and ‘Burgund Mare’ cultivars were investigated. The wine samples were obtained from micro-wine production under conditions of 2014, 2015, 2016 from Dealu Bujorului vineyard. The determination of 13 elements was performed with ICP-MS. The high level of Ca (64.81-62.49 mg/L), Mg (132.61-101.44 mg/L) and Fe were observed in the wine samples analysed. Heavy metals like As, Cd, U, Hg and Pb was found below acceptable limits. Concentration of Na (1 mg/L), Cu (1 mg/L), As (0.2 mg/L), Cd (0.01 mg/L), Zn (5 mg/L) and Pb (0.15 mg/L) metals in analysed wine samples were under Maximum Permissible Limits (MPL), respectively as published by the Organization of Vine and Wine. Calcium and magnesium were the most abundant elements in all investigated wine samples. Concentration of Na (1 mg/L), Cu (1 mg/L), As (0.2 mg/L), Cd (0.01 mg/L), Zn (5 mg/L) and Pb (0.15 mg/L) in analysed wine samples were under Maximum Permissible Limits (MPL), respectively as published by the Organization of Vine and Wine.

The purpose of this study is to know better the concentration of chemical elements in the soil from Dealu Bujorului vineyard. The determination of the ten elements from the soil samples was performed using ICP-MS. The results showed diverse patterns of cadmium, lead, uranium, mercury, arsenic, strontium, cobalt, copper, nickel and chromium, all the elemental content studied were under the maximum limit admitted, except for copper (average 356.03 mg/kg while M.L.A. = 20 mg/kg).

Wine is considered to be a hydro alcoholic solution with more than 1000 components associated in an extremely complex manner, some of them can pass from grapes in an unchanged state, and some are formed during alcoholic and malolactic fermentation, while others appear due to the reactions between substances in their natural state, or based on the existing ones. The presence of phenolic substances in wine is essential, representing a major contribution in the forming of specific characteristics such as: colour, aroma and taste, thus allowing the distinction between different types of wine. The main purpose of this research is to evaluate the physicochemical composition of the three acknowledged varieties of young wine from the Dealu Bujorului vineyard (‘Merlot’, ‘Cabernet Sauvignon’ and ‘‘Fetească Neagră’’), obtained under the culture conditions of 2012 - 2013 - 2014 years. The oenological parameters were determined after the national STAS regulations and effectively OIV methods. Statistical methods were employed in order to assess the organic and inorganic potential of wine. The ecoclimatic conditions studied in the Dealu Bujorului, Bujoru Wine Centre, highlighted the exceptional viticultural character of Romania as well as the authenticity character encountered in the large variety of wines produced in this area. Results also show that the vine varieties of cultivated in the Vineyard of Dealu Bujorului have a high content of macroelements (‘Merlot’ (890.01 ± 6.35 mg/L (2013)), ‘Cabernet Sauvignon’ (111.36 ± 3.53 mg/L (2013)) and Feteasca neagră (97.30 ± 0.46 mg/L (2014)) that are very important for human’s health. Wine quality parameters analyzed shows that are influenced by the area of culture of vine but also they are influenced by the technology of winemaking.

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).

The research was carried out between 1980 and 2016 and its objective is to establish the trend of risk and stress factors in the Bujoru vineyard ecosystem. Viticulture is sensitive to climate change, therefore depending on the evolution of the weather the most efficient technological measures that minimize the effect of climate change must be established in the future. For the Bujoru vineyard ecosystem, drought is a frequent phenomenon, with long periods of time without quality rainfall followed by short periods of torrential rain, over the average quantity, not entirely able to be harnessed. Evolution of precipitation marks a cyclical trend of about 7-8 years during which rainy years alternate with droughty years. The precipitation deficit is especially occurring during the winter and at the beginning of the vegetation period (April to May). The air temperature during the vegetation period shows a trend of growth until 2003, followed by a decrease until 2014, followed by a growth trend. The frequency of tropical days (days with Tmax> 30 ° C) shows a rising trend during the vegetative period and the number of days during winter (Tmax <0 0 C) shows a decreasing trend.

The vineyards in the south of Moldova are increasingly affected by climate change occurring over the last period. Reducing crop quality and quantity a hub of grape vineyards and affecting the occurrence of early winter frosts and excessive negative temperatures, the late spring frosts and drought of the vegetation period, result in significant losses for vineyard property. Witnessing lately to torrential rainfall, prolonged drought, excessive years of normal or dry years followed by rain. All these aspects influence of soil water reserves have mostly hydric deficit since June. The paper presents analysis of rainfall and soil humidity regime. For analysis of rainfall were recorded at weather station data used to SCDVV Bujoru. They collected soil samples monthly, on the horizon 0-100 cm, from 20 to 20 cm. With hydro index was calculated soil moisture in the soil available. Analyzed during the early vegetation period the soil water reserve is located in the humidity range of 55-70% of assets and soil water deficit is greatest in August. [ABSTRACT FROM AUTHOR]
