Research on Behavior of Some Mixed Grape Varieties and Biotypes of Buziaş-Silagiu Area

Abstract

Buzias-Silagiu area, situated in Timis county, has a long tradition for the cultivation of vines in the western part of Romania. It is an area characterized by a very favorable climate and soil conditions, offering the possibility of successful cultivation of many varieties, from the earliest to more autumnal. In this area there were identified numerous local varieties and biotypes, characterized by valuable agrobiological and technological features for growers and consumers, but also for breeders: high production, high quality, drought resistance, frost resistance, tolerance to some diseases and pests. Some of this varieties and biotypes show ampelografical and technological caracteristics being used both for fresh consumption and for producing wine with lower alcoholic strength. The research has been conducted in the private plantations from Buzias-Silagiu area and concerned 6 local varieties and biotypes with mixed features: Alb aromat de Silagiu, Coada oii, Gras aripat de Silagiu, Marcoveaţa, Roz aromat, Roz batut. We focused on qualitative and quantitative caracteristics, wood maturation and buds viability in comparison with mixed caracteristics variety Chasselas. The witness selected is a very valuable variety, known worldwide and which is found in the vine varieties of reference area. The methods of research were the usual ones: determinations, measurements, visual examinations. The best results concerning grapes’ quality were obtained by Alb aromat de Silagiu variety wich accumulated 184.67 g/l sugar and an alcoholic potential of 10.86 degrees alcohol volume. Gras aripat de Silagiu and Coada oii stood out for productivity. Regarding the viability of buds, Alb aromat de Silagiu exceeded the witness.
