AGROBIOLOGICAL AND TECHNOLOGICAL CHARACTERISTICS OF VINE CULTIVARS CHARDONNAY AND RHEIN RIESLING IN TIKVESH WINE REGION

Abstract

Chardonnay and Rhein Riesling are white grape varieties that are used in producing high quality white wines. In Macedonia the production of wine grape is more than 2/3 from the whole grape production. With specific vine training we can plan the yield, make the shape and also to produce the desired quality of the wine grape. All the unnecessary shoots that are developed are removed until the start of the vegetation. The research is focused on the possibility of using different ways of pruning to achieve the best results in the yield and quality of the grape and also for introduction of machine pruning and machine harvest. The research is conducted on the
wine grape varieties: Chardonnay and Rhein Riesling. On the two researched grape varieties there are 4 variants of vine training from which one is Control. For the researched variants and grape varieties, the percentage of developed shoots is calculated, potential fertility, number of clusters per vine and shoot, cluster mass per bud and variant, grape yield per vine and hectare, total sugars and total acids. Results from the research in 2016 for the grape yield per vine and per bud, yield per vine, chemical analysis for sugar content and total acids show that the best variant from the Chardonnay is Variant 3 and the Rhein Riesling is Variant 2.
