Sažetak
With the restoration of the scientific studies at the Institute for agriculture and tourism, at the end of the 1980s, systematic studying of training systems started. At the beginning of the 1990s an experimental plantation of training systems has been set on the Institute's grounds amongst which Fillari binati, low cordon, Lira, Guyor and GDC on varieties Cabernet sauvignon. Serving the needs of the research, we have analyzed the results of three harvests, dated 7th Oct. 1999, 18th Sept. 2000 and 24th Sept. 2001. The clone R5 of Cabernet sauvignon has been grafted on the SO4 rootstock. The investigated were yield parameters as yield/vine, yield/hectare, average cluster weight and number of cluster/vine and quality parameters as soluble solids, acid content, pH. The worst result in this research has shown training system Filari binati. Cordon has shown the best yield results, the best yield per hectare and the highest soluble solids in grapes together with optimal level of acids. Guyot, Lira and G.D.C. have also shown satisfactory esults, concerning yield per hectare as well as grape quality. The results of our research suggest that Cordon, Guyot, Lira and G.D.C. can be successfully used in viticulture in Istria. The choice of training system will certainly depend on many variables, such as the size and location of the vineyard, availability and training edgree of manpower, existing equipment and machinery, type of wine-production etc. main problem with the introduction of new training systems, Lira and G.D.C. to Istria is certainly lack of specific equipment and machinery on market.
