Effects of cluster tipping on yield and quality of uslu and cardinal table grape cultivars

Bu araĢtırma, Uslu ve Cardinal üzüm çeĢitlerinin verim ve kalitesi üzerine salkım ucu almauygulamalarının etkilerinin saptanması amacıyla, Çanakkale/Türkiye‟de yürütülmüĢtür. Tane çapları 5 7 mmolduğunda, mevcut salkımların uçları 1/3, 1/6 ve 1/12 oranında kesilmiĢtir. Uslu üzüm çeĢidinde, salkımuzunluğu (cm), salkım eni (cm), salkım sıklığı (1 9), tane sayısı/salkım (adet), tane ağırlığı (g) ve titre edilebilirasitlik (%) parametreleri uygulamalardan etkilenmiĢtir. Cardinal üzüm çeĢidinde, salkım uzunluğu (cm), salkımsıklığı (1 9), tane sayısı/salkım (adet), tane ağırlığı (g), suda çözünebilir kuru madde (SÇKM) (%), titreedilebilir asitlik (%) ve olgunluk indisi parametreleri uygulamalardan etkilenmiĢtir. Uslu ve Cardinal üzümçeĢitlerinde salkım ucu alma uygulamalarının üzüm verimine önemli bir etkisi olmamıĢtır. Salkım ucu almauygulamalarının, Uslu üzüm çeĢidinde salkım uzunluğunun 1/3‟ü, Cardinal üzüm çeĢidinde ise 1/6‟sı oranındagerçekleĢtirilmesinin, üzüm kalitesini arttırıcı yönde pozitif ve yeterli bir etki sağladığı belirlenmiĢtir.

Salkım ucu kesme uygulamalarının uslu ve cardinal üzüm çeşitlerinin verim ve kalitesi üzerine etkileri

This research was conducted in Çanakkale, Turkey aimed to study the effects of cluster tippingapplications on the yield and quality of Uslu ( V. vinifera L.) and Cardinal ( V. vinifera L.) grape c ultivars. Whenthe berries were 5 7 mm, the clusters were tipped at 1/3 rd, 1/6th and 1/12th of the cluster length. In Uslu, clusterlength (cm), cluster width (cm), cluster compactness (1 9), number of berries/cluster (n), berry weight (g) andtitratable a cidity (TA) (%) parameters were affected by the applications. In Cardinal, cluster length (cm), clustercompactness (1 9), number of berries/cluster (n), berry weight (g), total soluble solid (TSS) (%), titratableacidity (TA) (%) and maturity index parame ters were affected by the applications. Yield was not affected bycluster tipping in Uslu and Cardinal grape cultivars . It was concluded that the cluster tipping applied to the Usluin a proportion of one third and to the Cardinal in a proportion of one sixth of the cluster length would bepositively sufficient in terms of incre asing the grape quality.
