Yüksek rakımda yetiştirilen bazı sofralık üzüm çeşitlerinin fenolojik ve kalite özellikleri

This study was carried out in a vineyard located in Göksun town of Kahramanmaraş (elevation: 1420 m) in 2018. Yalova İncisi, Kabarcık and Kirkit grape cultivars were investigated for date of phenological stages and fruit characteristics. Yalova İncisi was the earliest matured cultivar. The shortest period of time from bud-burst to maturing was observed in Yalova Incisi (138 days). Bud-burst happened at the end of April and flowering was observed in mid-June. Clusters of Yalova Incisi were harvested at 18.8% brix and 0.52% acidity on September 5. Kirkit matured in early October at 22.8% brix and 0.67% acidity with maturity index was 34.03. However, Kabarcık was not fully matured at this date and maturity index was measured as 14.24. Because of the occurrence of early frosts in autumn, Kabarcık had to be harvested earlier on the beginning of October. The largest clusters were found in Kabarcık (583.99 g) and the largest berries in Yalova Incisi (4.85 g). In terms of berry firmness, Kirkit (2.91 N) was found to be stronger than the others, and berry detachment force of the berries were found to be strongest in the Kabarcık (1.88 N). The highest number of seeds per berry was measured in Kabarcık (3.2 piece berry -1 ). Yalova Incisi and Kirkit cultivars were suitable for the region but cultivation of the Kabarcık variety was risky due to early frosts in autumn. It is recommended that adaptation studies of other early and very early grape cultivars should be carried out in that region.
