Abstract

This
study was conducted on grownTilki Kuyrugu grape variety (Vitis vinifera L.) in Mersin province in Turkey in 2016. The
cultivar is 12 years old and grown on their own roots and evaluated as table.
In this research, it was investigated whether the applications 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 on yield and yield components of Tilki Kuyrugu grape variety. The
results were obtained as the highest fresh grape yield were (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; the highest must yield was (700.00
ml/kg) with 1/9 CTR+BA application; No significant effects were found
statistically on maturity index value. To increase fresh grape yield and
cluster weight of Tilki Kuyruğu grape variety can be advice 1/3 CTR, 1/9 CTR and
1/3 CTR+BA applications.
