Brassinosteroidlerin Trakya İlkeren (Vitis vinif era L.) sofralık üzüm çeşidinin verim ve kalitesi üzerine olan etkileri

Bu araştırma bir brassinosteroid bileşiğinin (22S, 23S- homobrassinolid) bağda yetişen sofralık üzüm çeşidi Trakya İlkerenin verim ve kalitesi üzerine olan etkilerini tespit etmek amacıyla yürütülmüştür. Omcalar iki vejetasyon döneminde çiçeklenme başlangıcında (Mayıs ayının ilk haftası) muamele edilmiştir. Solüsyon 0 (kontrol), 10-3 ve 10-4 mgL-1 konsantrasyonlarında hazırlanmıştır. Kontrol grubunun salkımları 16°Brix değerine ulaşınca tüm deneme hasat edilmiştir. Verim ve kalite özellikleri tespit edilmiştir. Brassinosteroid bileşiği dozlarının sadece tane sapı kopma kuvveti üzerine etkili olduğu tespit edilmiştir. Salkım uzunluğunun uygulama yılına bağlı olarak değiştiği belirlenmiştir. Uygulanan dozların Trakya İlkeren çeşidinin diğer verim ve kalite özellikleri üzerine etkili olmadığı görülmüştür.

Effects of Brassinosteroids on Yield and Quality of Table Grape CultivarTrakya Ilkeren

This research was carried out to determine the effects of a brassinosteroid compound (22S, 23S- homobrassinolide) on yield and quality attributes of a field-grown table grape cultivar Trakya Ilkeren. The vines were sprayed at anthesis (first week of May) with the compound over two growing seasons. The solutions were prepared at the concentrations of 0 (control), 10-3, and 10-4 mgL- 1. All clusters were harvested when those of the control vines reached 16°Brix. Yield and quality parameters were analyzed. It was found that brassinosteroid compound only had an effect on pedicel strength to the berry. There were also seasonal differences in the cluster length. It was concluded that the doses applied did not influence yield and quality attributes of the Trakya Ilkeren grapes.
