A comprehensive analysis of phenological timing and growth intervals for
eight red and thirteen white wine grape cultivars in the region of Sremski
Karlovci was performed using a long-term (1986-2011) data set. Four
phenological stages of grapevine were examined: beginning of budburst,
beginning of flowering, beginning of veraison and harvest. The phenological
stages studied exhibited a 30 to 51 day variation between the earliest and
latest years for red cultivars and 29 to 49 day variation for white
cultivars. The beginning of flowering exhibited the least, while harvest
showed the highest inter-annual variation. The difference between red and
white cultivars was the greatest for harvest - the mean harvest date averaged
over all red cultivars was 24 September and over all white cultivars 14
September. The beginning of flowering to the beginning of veraison interval
showed the smallest and budburst to harvest interval the greatest year-toyear
variability. The beginning of budburst to harvest period for the cultivars
examined averaged 165 days for red and 156 days for white cultivars, with the
mean interval range of 58 days for red and 55 days for white cultivars. In
addition, it was found that a variability of the onset and duration of
phenological phases was greater between years for a single cultivar than
among cultivars within individual years, meaning that climatic factors are
more important than genetic characteristics of cultivars for phenological
timing.
