The Influence of Climatic Conditions on The Vegetative Development of Vine Varieties Grapes Grown inThe Wine-Growing Center - Copou Iași

Abstract

Environmental factors in a vineyard ecosystem form a complex of factors which are interdependent and can restrict, hinder or stimulate the growth and development of the vine. The singular or cumulative effects of climatic risks and identification of most vulnerable areas are basic criteria in elaborating and founding a decisional system for long term agro-climatic management. In the last years, the changes of the environmental factors have become more and more visible. The repercussions are registered in thevineyard system as well; the grape varieties alter their annual life cycle. In the northern area of Romania, an increase of the thermal regime and a decrease of rains led to a thermic and hydric stress of plants. The climatic changes of the last years, more or less at random, can seriously harm the homogeneity of viticultural biocenotic conditions, with unpredictable implications on the quantity and quality of the grape harvest. This study aims to contribute scientific and practical on how the climatic factors in the years 2012/2013, as atypical, influenced vegetative growth and further development of grapevines varieties ‘Gelu’ and ‘Paula’ compared with ‘Aromat de Iași’.
