Abstract

This research was carried out in order to determine the effects of leaf water potential and defoliation applications on the cluster characteristics by using Merlot/41B grafting combination in Chateau Kalpak vineyards in Sarkoy district of Tekirdag province. The trial was carried out in a vineyard for two years in the vegetation period of 2019-2020 and 2020-2021. In the experiment, there were leaf water potential [S0 (Control=no irrigation), S1 (-0.3/-0.5 MPa), S2 (-0.5/-0.7 MPa) and S3(<-0.7) MPa)] and defoliation methods; Control, Full Window, Right Window and Left Window were done respectively. As a result if vigneron’s want; low cluster width, low cluster length, low cluster weight and low number of berry per cluster in Merlot cv. in Sarköy district of Tekirdağ was concluded that Left Window application can be selected. And also S3 application can be preferred when low cluster weight, low cluster volume and low cluster compactness are desired.

Özet

Bu araştırma Tekirdağ ili Şarköy ilçesinde Chateau Kalpak bağlarında Merlot/41B aşı kombinasyonu kullanılarak yaprak su potansiyeli ve yaprak alma uygulamalarının salkım özellikleri üzerine etkilerini belirlemek amacıyla yapılmıştır. Deneme 2019-2020 ve 2020-2021 vejetasyon periyodunda bağda iki yıl süreyle yürütülmüştür. Yapılan yaprak su potansiyeli uygulamaları [S0 (Kontrol=sulamasız), S1 (-0.3/-0.5 MPa), S2 (-0.5/-0.7 MPa) ve S3 (<-0.7 MPa)] ve yaprak alma uygulamaları; Kontrol, Tam Pencere, Sağ Pencere ve Sol Pencere uygulaması şeklinde gerçekleştirilmiştir. Sonuç olarak; Tekirdağ ili Şarköy ilçesinde Merlot üzüm çeşidi yetiştiriciliğinde düşük salkım eni, salkım boyu, salkım ağırlığı ve salkımdaki tane sayısı elde edilmesi istendiğinde; Sol Pencere uygulamasının seçilebileceği, düşük salkım ağırlığı, salkım hacmi ve salkım sıklığı istendiğinde de S3 stres uygulamasının tercih edilebileceği sonucuna varılmıştır.
