RESEARCH REGARDING THE BEHAVIOR OF CLONAL FETEASCA NEAGRA 10 PT TO LOCAL CLIMATE CHANGES

Throughout numerous research stations and prestigious institutes and wine traditions in our country, owner of germplasm fond, we encounter vineyard center Pietroasa, which quality attributes derive from, on one hand the ecopedoclimatic specific conditions existing here and on the other hand from the scientific activity headed to creating new vine varieties and improving the main soils of the assortment through clonal selection. In the last years, though, as in almost all our country regions, we assist with certain worry to a series of extreme climate events (strong winds, maximum extreme temperatures in summer, minimum extreme temperatures in winter as well as the phenomenon called freezing rain, all with effects on the normal growing cycle of vine plants. In this paper it is observed the influence of the climate changes on the agrobiological and technological potential of the clonal selection Feteasca neagra 10, the newest achievement of S.C.D.V.V. Pietroasa (patented in 2010) between 2010-2012. Climate data has been collected from the research station’s own weather station and implied daily observations regarding the evolution of the parameters – temperature, precipitations, insolation – and based on these parameters were calculated the climate indexes that define the favorability degree of an area, as well as the Huglin index. The results obtained after the study prove that they are in direct correlation with these area climate changes, and that on the short run have a positive influence on the precocity of grape maturation, on the sugar accumulation potential, all together giving an extra quality to the final product, the wine.
