Abstract :Different soil tillages and leaf removal treatments effects on water stress and berry metabolite accumulation was studied in this research at the conditions of Tekirdağ province. Three different soil tillage treatments were used; conservative soil tillage (CST), conservative soil tillage + traditional soil tillage (CST+TST) and traditional soil tillage (TST). 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 research; climatological data and phenophases, leaf water potentials, grape must characteristics [SSC, total acidity, pH, sugar concentration, sugar amount per berry, total (-L) malic acid, total anthocyanin, total polyphenol index (TPI)], yield per vine, and berry maturation indexes (pH2*SSC and sugar/titratable acidity) were determined. According to results; with CST+TST treatment, leaf water potential and yield were increased while SSC, sugar concentration and total anthocyanins decreased. With CST treatment leaf water potentials and yield were decreased while SSC, total acidity, sugar concentration, total anthocyanins and TPI increased. With ML leaf removal treatment; yield was decreased while total acidity, TPI and malic acid increased. With SL treatment; SSC, sugar concentration and total anthocyanin were increased while must pH decreased. In conclusion, for cv. Syrah red wine cultivar, CST soil tillage treatment and control (ML+SL) leaf removal treatment were recommended in Tekirdag province conditions.Keywords : Syrah, Yaprak su potansiyeli, Toprak işleme, Yaprak alma, Metabolit birikimi
