The viticulture, a traditional branch of the national economy, is closely related to climatic conditions because the Republic of Moldova territory represents the northern border of its territorial location. Therefore the knowledge of regional particularities of grapevine productivity formation in dependence of current agro-climatic conditions is of particular interest. Along with accelerated climate change in last decades over the Republic of Moldova territory, we find that are essential changes concerning agro-meteorological conditions, at the same time comprehensive researches that would reflect the actual impact of climate change on grapevine are limited. There are known researches, but in the context of changes that occur at regional level it is necessary to supplement permanently the database in order to elaborate an appropriate estimation of current climate conditions. The above reported facts show the importance of parameters influencing the grapevine productivity time and space study in Republic of Moldova.
