Influence of Varietal Variety and Climatic Year on the Phenology of Some Table Grape Varieties Grown in the Murfatlar Area, Romania

This study aimed to assess the influence of recent climatic conditions and cultivar on the timing of key phenological stages in grapevines. For this purpose, five table grape varieties with different ripening periods, grown at the Murfatlar viticultural center and vineyard in Romania, were studied. This vineyard is challenged by current cli-matic changes. At the local level, data have been recorded showing constant climatic changes, with changing temperature and humidity regimes. These data will lead to management problems that other vineyards are already facing. The study covered the period from 2000 to 2019 and tracked the timing of the onset of vegetative phases, as recorded in the number of days from January 1 to that point, according to the BBCH phenological scale. The results showed that the length of the vegetation period depends not only on the variety but also on the viticultural year, due to annual climatic variability. Changes in the duration of the vegetative phases were evidenced, with a trend towards advancing ripening.
