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 insert ignore into journalissuearticles values(CST);, Conservative Soil Tillage + Traditional Soil Tillage insert ignore into journalissuearticles values(CST+TST); and Traditional Soil Tillage insert ignore into journalissuearticles values(TST); and three different leaf removal applications were used; Control insert ignore into journalissuearticles values(ML+SL); treatment insert ignore into journalissuearticles values(treatments which main leaf and secondary leaves left together on vine);, ML insert ignore into journalissuearticles values(treatments which main leaves left on the vine);, SL insert ignore into journalissuearticles values(treatments which secondary leaves left on vine);. In order to reveal the effects of different cultural practices on the must composition; SSC insert ignore into journalissuearticles values(°Brix);, total acidity insert ignore into journalissuearticles values(g/L);, pH, sugar concentration insert ignore into journalissuearticles values(g/L);, sugar amount in berry insert ignore into journalissuearticles values(mg/berry);, total malic acid insert ignore into journalissuearticles values(g/L);, total anthocyanin insert ignore into journalissuearticles values(mg/kg);, and total phenol index insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(ML+SL); from leaf removal treatments were positive effected must composition in cv. Cabernet-Sauvignon growing in Tekirdag conditions.
