AGROBIOLOGICAL AND TECHNOLOGICAL VALUE OF SOME ANCESTRAL ROMANIAN VARIETIES IN THE CONDITIONS OF THE ODOBEȘTI VINEYARD

Rezumat

In the context of global warming and the conservation of biodiversity in wine-growing areas, one of the main directions of scientific research is the return to ancestral varieties from the old assortment specific to Romanian vineyards. This paper presents a study on the agrobiological and technological value of four old indigenous grape varieties (Vitis vinifera L.) for white wines (′Galbenă de Odobești′, ′Cruciuliță′, ′Pîrciu′ and ′Gordin′), under the conditions of climate change in the Odobești vineyard, Vrancea county. These varieties demonstrated high fertility potential (71.9 - 92.8 % fertile shoots) and valuable technological characteristics, with a production that varied between 3.50 kg/vine for the 'Pârciu' variety and 5.79 kg/vine for the 'Gordin' variety, under conditions of good accumulation of sugars in the berries (176 - 214 g/L) and a balanced total acidity (>5.3 g/L tartaric acid).
