The evolution over time of the development of vegetation phenophases of the vine varieties cultivated in the Copou Iaşi wine center in the context of climate change

Abstract

In the last 20 years there has been a tendency of change in the evolution of climatic factors, which makes it increasingly difficult to accurately predict the timing of vegetation phenophases in vines. Their dynamic analysis, in close correlation with the evolution of climatic factors specific toIasi vineyard, from 2000 to 2019, showed that they were conditioned by the level and action of climatic factors and the hereditary specificity of cultivated varieties. The increase of temperature values (average annual temperature, average temperature in the first and second decades of June, average temperature in July, etc.), determined the advance of the onset of phenophases and shortened their duration, especially in dry years.
