The phenological spectrum of some vine varieties cultivated in Odobeşti vineyard in the context of climate change

Abstract

In the last 20 years there has been a tendency to change in evolution 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 to Odobeşti vineyard, from 2000 to 2019, highlighted the fact that they were conditioned both by the level and action of climatic factors and by the hereditary specifics 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.
