Abstract :The aim of this research was to examine the effects of different cultural practices on composition of must in cv. Cabernet-Sauvignon. There were three soil tillage treatments; Conservative Soil Tillage (CST), Conservative Soil Tillage + Traditional Soil Tillage (CST+TST) and Traditional Soil Tillage (TST) and three different leaf removal applications were used; Control (ML+SL) treatment (treatments which main leaf and secondary leaves left together on vine), ML (treatments which main leaves left on the vine), SL (treatments which secondary leaves left on vine). In order to reveal the effects of different cultural practices on the must composition; SSC (°Brix), total acidity (g/L), pH, sugar concentration (g/L), sugar amount in berry (mg/berry), total malic acid (g/L), total anthocyanin (mg/kg), and total phenol index (TPI) criteria were examined. According to results; CST was led to decrease in sugar concentration, total anthocyanin, malic acid and SSC. CST+TST was led to increase total anthocyanin content while led to decrease in SSC, pH, TPI amounts. Through with leaf removal applications; ML treatment was led to increase in total acidity while decrease in SSC and malic acid content. SL treatment was led to decrease in SSC, pH, sugar concentration. As a result, CST from soil tillage treatments and control (ML+SL) from leaf removal treatments were positive effected must composition in cv. Cabernet-Sauvignon growing in Tekirdag conditions.Keywords : Cabernet-Sauvignon, Toprak işleme, Yaprak alma, Şıra özellikleri
