The Effects of Cluster Tip Reduction and Boric Acid Applications on Yield and Yield Components of Tilki Kuyruğu Grape Cultivar
Journal Title: ÇOMÜ Ziraat Fakültesi Dergisi - Year 2017, Vol 5, Issue 1
Abstract
This study was conducted on grownTilki Kuyrugu grape variety (Vitis vinifera L.) in Mersin province in Turkey in 2016 on the cultivar which is 12 years old and grown on their own roots and evaluated as table grape. In this research, it was investigated that the effects of Control (C), 1/3 Cluster Tip Reduction (1/3 CTR), 1/6 Cluster Tip Reduction (1/6 CTR), 1/9 Cluster Tip Reduction (1/9 CTR), 1/3 CTR+Boric Acid (BA), 1/6 CTR+BA, 1/9 CTR+BA applications on yield and yield components of Tilki Kuyrugu grape variety. The results were obtained as the highest fresh grape yield (10.26 kg/vine) with 1/9 CTR, (10.14 kg/vine) with 1/3 CTR and (10.09 kg/vine) with 1/3 CTR+BA applications; the highest cluster weight were (341.89 g) with 1/9 CTR, (338.11 g) with 1/3 CTR and (336.22 g) with 1/3 CTR+BA applications; the highest 100 berry weight were (513.39 g) with 1/9 CTR, (511.38 g) with 1/6 CTR+BA, (509.28 g) with 1/9 CTR+BA, (507.06 g) with 1/6 CTR, (487.31 g) with 1/3 CTR+BA and (477.79 g) with 1/3 CTR applications; and the highest must yield was (700.00 ml/kg) with 1/9 CTR+BA application. The effects of the applications on the maturity index value were not found signicificant in respect of statistically. It can be recommendedwe can recommend 1/9 Cluster Tip Reduction application to improve fresh grape yield, cluster weight and 100 berry weight of Tilki Kuyruğu grape variety.
