Effects of cluster removal treatments on yield and quality in table grapes

In this study, it was carried out in Manisa (Sarıgöl / Emcelli) province in 2018 years. Sultani Seedless and Red Globe grape varieties grown in their roots were used in this study. Both grape varieties in the vinestocks fruit set and veraison in the period of 10, 15, 20 clusters / vine was applied in the cluster removal. Three different dates were harvested. The study was carried out in randomized plots with two factors according to factorial experiment design. Three comparisons were made and LSD (0.05) test was used for comparison of means. In each harvest period, yield, cluster size, TSS, acid, berry width, berry weight, berry hardness, color L, color a, color b, total phenolic and flavonoid values were determined in the berry. Sultani Seedless grape varieties and Red Globe grape cultivar yield increased as the number of bunches increased (respectively: 9804-12156-13773 kg/vine; 13843-17309-20159 kg/vine). However, as the number of clusters increased, cluster weight, TSS, berry width and length, berry weight, total phenolic, anthocyanin and flavonoid values decreased.
