Abstract:

 The research was conducted in 2017 and 2019 on 15 year old vines with the Cabernet-Sauvignon110R graft combination, located in the vineyard owned by Barel Vineyards. The objective of the research was to evaluate the impact of three distinct abiotic stresses shock action, leaf injury, UV-C irradiation applied during three different phenological periods veraison, veraison-harvest, and harvest on cluster characteristics. For five days, the vines were subjected to the three abiotic stresses: shock action using a plastic hammer at 08:00 AM and at 19:00 PM for 1 min each time, leaf injury striking the leaves firmly once with a flexible stick, and UV-C irradiation 08:00 AM and 19:00 PM for 1 min each time, and a Control. The harvests were carried out on 24.09.2017 and 27.09.2019 following the applications. To reveal the characteristics of the cluster, the number of berries per cluster, cluster width-length cm, cluster weight g, cluster volume with and without spaces cm³, and cluster compactness value were measured. Cluster compactness values were classified as follows: less than 0.7 as very compact, 0.7-0.9 as compact, 0.9-1.1 as medium, 1.1-1.3 as loose, and more than 1.3 as very loose. Cluster weight decreased the most with applications during the veraison period 139.52 g. Lower values were also observed for the other examined criteria with stress applications during the veraison. In conclusion, the applied abiotic stress treatments did not significantly affect cluster characteristics.

 Araştırma, 2017 ve 2019 yıllarında, Barel Vineyardsa ait bağda, Cabernet-Sauvignon110R aşı kombinasyonuna sahip 15 yaşındaki asmalar üzerinde yürütülmüştür. Araştırmada amaç; 3 farklı fenolojik dönemde ben düşme, ben düşme-hasat ve hasat uygulanan 3 abiyotik stresin darbe, yaprak yaralama, UV-C salkım özelliklerine etkisini belirlemektir. Beş gün süre ile asmalar 3 abiyotik strese tabi tutulmuştur; darbe plastik çekiç ile 08:00da birkez ve 19:00da 1 kez 1 dk, yaprak yaralama bir kez yaprakların esnek çubuk ile yaralanması ve UV-C 08:00de ve 19:00de 1 kez 1 dk ve Kontrol. Uyulamaların ardından hasatlar 24.09.2017 ve 27.09.2019 tarihlerinde gerçekleştirilmiştir. Salkımın özelliklerini ortaya koymak için; salkımdaki tane sayısı adet, salkım eni-boyu cm, salkım ağırlığı g, boşluklu-boşluksuz salkım hacmi cm3, salkım sıklığı değeri 0.7den küçük değerlerde çok sık, 0.7-0.9 değerleri arasında sık, 0.9-1.1 değerleri arası orta, 1.1-1.3 değerleri arası seyrek, 1.3 değerinden fazla olduğunda çok seyrek olarak sınıflanmıştır. Salkım ağırlığı en çok ben düşme döneminde 139.52 g yapılan uygulamalarla düşmüştür. Diğer incelenen kriterler açısından da ben düşme döneminde yapılan stres uygulamalarıyla düşük değerler alınmıştır. Sonuç olarak gerçekleştirilen abiyotik stres uygulamalarının salkım özellikleri üzerinde belirgin bir fark yaratmadığı söylenebilir.
