Climatic changes on the global level have consequences in changes of meteorological and climatologic conditions in vinegrowing areas. The aim of this paper was to analyze trends of the meteorological elements and determine suitability of growing grapevine cultivar in a viticulture region. Trend analysis was done, based on the data for South-Banat sub-region, an important resource for the production of grapes and wines in Pannonia plain (Vršac: H=83m, φ=45 09 N, λ=21 19 E).

Climatic changes in the last two decades on global level are presenting the fact that the planet Earth is getting warmed up. Significant temperature increasing on global level has consequences in air temperature changing on even smaller proportion. The aim of this paper is to analyze trends in air temperature, as a very important meteorological element for successful grapevine growing.

Phenological stages of white wine varieties grown in the "Radmilovac" collection vineyard were recorded during a three- year period. The included stages were: time of bud burst - shoot growth, flowering, véraison and full ripening. The number of days, sum of active and sum of effective temperatures were established for each phenological stage, 12 features in total.

In two wine-growing areas with different climatic characteristics 12 cultivars intended for the production of white wines were studied. The climatic characteristics include: mean annual air temperatures, mean vegetation air temperatures, heliothermal coefficient, hydrothermal coefficient and active temperatures sum from the moment of the growth of shoots to their full maturity for each studied cultivar. Elements of buds fruitfulness (6 features in total), yield, cluster mass, sugar quantity and grape quality were observed in both localities.

According to general characteristics of the climate of vineyard zones in Yugoslavia in 1976, ten (10) vineyard zones were established. For better presentation of the climate conditions of the vineyard zones of Yugoslavia in this work the data of 12 representative meteorological stations for the period 1951-1995 were used. Meteorological parameters are presented in tab.l and 2.
