Abstract
Changes in the climatic factors registered in the last 30 years have highlighted unfavorable trends in the evolution of climatic factors, respectively the increase in the thermal regime, especially in the frequency of hot periods, and a decrease in the amounts of precipitation, which led to the emergence of the phenomenon of pedological drought.
The long period of drought associated with a high thermal regime and a lower hygroscopicity of the air, installed during the period of intense growth of shoots and grapes, determined a reduction of the vegetative phenophases period, of shoot growth, and a slowdown of berry growth.
All these factors had a negative impact on the qualitative potential for the red wine cultivars, ‘Negru aromat’, ‘Cabernet Sauvignon’, and for the ‘Fetească neagra 4 Vl’ clone, by increasing the concentration of sugar in grapes by 17-20% and decreasing acidity by 20-30%.
