Abstract


Vines act as indicators in relation with ecoclimatic changes and they are particularly sensitive to temperature and precipitation changes.

Temperature is a limiting factor and define the distribution area for all plants. Climate change in viticulture is characterized by air temperature increase, rain reduction, intensification of extreme events, mild winter and heat shock in summer but with frost in April-May.

The main objective of this paper is to present the climatic conditions such as temperature, insolation, rainfall and the interaction of these parameters in Turda viticulture area, in the last years (2009-2019), in order to assess the oenological potential of the area. Comparing the thermal coefficient values (Ct) of our country (situated between the values 16-19), we can conclude that, in Turda area there is sufficient thermal resources for vine growth and fruition. Insolation and precipitations are in normal parameters for viticulture. The values of the real heliothermic index (IHr), hydrothermal coefficient (CH) and wine bioclimatic index (Ibcv) recorded in Turda winegrowing area (IHr=2.0; CH=1.3 and Ibcv=6.1) show that the ecoclimatic conditions from the studied area is favorable, that makes possible the production of grapes for white wines of high quality but also quality red wines, in some years.
