Özet:

In this study, optimum harvest times, cluster and berry characteristics of four grape cultivars (Hasandede, Eggs, and Horses) grown in Eggs (Eggs) ecological conditions were determined. In two consecutive years (2017-2018) yield, clusters, berry properties, water-soluble solid content, pH, titratable acidity, maturity index properties were determined. Some biochemical changes in grape varieties were followed during the ripening periods in the second year. The highest yield in both years was obtained from the variety of Horse Sheep (1421.2 and 1504.8 kg/day), while the lowest yield was obtained from Horse Sheep (619.4 and 578.31 kg/day). During the harvest period, the total acidity and pH values must be changed according to years and varieties. The total soluble solids (TSS) and pH values increased with maturation, whereas the total acidity was found to decrease until the last observation date. During the harvest period, all varieties reached optimal harvest maturity in both years.
