Özet
This research was conducted in Sarkoy district in Tekirdag province. Location of research plot was 40 degrees 37' 49.98 N latitude and 27 degrees 09' 28.00 E in longitude, with 41m altitude, in 2013 vegetation period. Experimental research design was completely randomized block in 4 blocks. Leaf water potential and cluster thinning applications were performed in order to determine cluster and berry characteristics. Four different levels of leaf water potentials (psi(leaf)); Control psi(pd) n epsilon(-0,3; -0,5MPa], psi(pd) n epsilon(-0,3; -0,6MPa] and psi(pd) n epsilon(-0,3; -0,7MPa] and two levels of cluster thinning applications (CTA); non cluster thinning (NCT) and 50% cluster thinning (50% CT) were performed in this research. Cluster characteristics (cluster lenght, width, weight, volume, berry number in cluster) and berry characteristics (berry fresh and dry weight, % dry weight, berry volume, berry density, berry skin area calculation, berry skin area / berry volume calculation) were investigated. psi(pd) n epsilon(-0,3; -0,5MPa] application resulted in highest cluster weight and cluster width; but the lowest in berry dry weight. On the other hand psi(pd) n epsilon(-0,3; -0,7MPa] application increased the yield and quality values. Control application decreased yield and quality values. Cluster thinning application did not affect the leaf water potential significantly. As a suggestion in cv. Sangiovese leaf water potential should be between n epsilon(-0,2; -0,35MPa] in berry set-veraison stage and between n epsilon(-0,3; -0,7MPa] in veraison-maturity stage in order to increase the berry sugar concentration (degrees Brix) 50 % cluster thinning applications should applied.
