STUDY REGARDING THE EVOLUTION OF QUANTITATIVE AND QUALITATIVE PARAMETERS IN VINIFERA VARIETIES FROM TÂRNAVE VINEYARD

In the present study, three varieties of grapes, Fetească regală (FR), Muscat Ottonel (MO) and Sauvignon Blanc (SB) were analysis. For a complete characterization of the grapes at harvest, the main analytical characteristics must be known: their sugar content (g /l), the total acidity (g/l H2SO4) and the mass of 100 grains. The study of the production behavior of the varieties was carried out over a period of three years (2017-2019). The results showed, the Muscat Ottonel cultivar is very well adapted in the three years of study, recording the highest values of this character (203.91g). The highest content in total acidity, in all three years, was registered by the Feteasca Regala variety (6.7 g /l H2SO4), recommended otherwise for the production of base wines in order to obtain sparkling wines

RESEARCH ON THE INFLUENCE OF SOME TECHNOLOGICAL FACTORS ON GRAPE PRODUCTION UNDER THE CONDITIONS OF THE TÂRNAVELOR VINEYARD

The paper presents the results of the researches carried out during the period 2017-2019, under the conditions of the Târnavelor Vineyard, in the Jidvei-Alba area, regarding the influence of some technological factors on the level of grape production. The factors considered in the study were: Factor A - irrigation regime, with graduations a1 - non-irrigated, a2 - irrigated at 50% IUA; Factor B - fertilization, with graduations b1 - basic fertilization, b2 - basic fertilization + chemical fertilization; b3 - organic fertilization; Factor C, biological material, with graduations c1 - Muscat Ottonel variety, c2 - Feteasca Regala variety, c3 - Sauvignon Blanc variety. The production results recorded during the three years of experimentation highlighted in particular the favorable effect of irrigation on the production of grapes, in all three varieties, regardless of the applied fertilization level
