INFLUENCE OF VARIETY AND TYPE OF CULTIVATION (ORGANIC AND CONVENTIONAL) ON QUALITY, IN FOUR TABLE GRAPE VARIETIES, GROWN IN CLUJ COUNTY, ROMANIA

Abstract

Four table grape varieties (Timpuriu de Cluj, Napoca, Chasselas doré, Muscat Hamburg) were tested in 2007-2008, Cluj county, Romania, under two types of cultural practices: organic and conventional. In the conventional system were used chemical fungicides and for the organic treatments were applied ecological products. In this study the following parameters were analyzed for the five wine grape varieties: average weight of grapes (g), the total acidity of must (gH2SO4 /l must) and sugar content of grape (g sugar/l must). The experiment was a bifactorial series (cultivar x type of cultivation) with four table grape varieties grown in two different systems, organic and conventional. The Napoca variety has registered good values for all parameters analyzed and these results recorded suggests that is a high adaptability to the organic culture system for this cultivar.
