Formation Of Çotanak Groups According To Direction Of Branches In The Ocaks Tombul And Palaz In Hazelnut Varieties

Abstract

This study was conducted with Tombul and Palaz hazelnut varieties as three recurrences in 2010. Çotanak groups and çotanak lengths was determined according to direction of branches which in the Ocaks (a Turkish name of the training or growing system used for hazelnuts).In this study, while there was maximum 7 çotanaks on the branches of palaz hazelnut variety, on the tombul hazelnut it was determined as 11. At the Palaz variety, it was determined that there was 54.66, 54.99, 68.33, 81.33 çotanak groups respectively in the east, west, north, south directions, likewise at the Tombul variety there was 106.33, 83.33, 96.34, 115.00 çotanak groups. It was determined that for Palaz variety, the highest çotanak length was 49.96 mm in the east, the lowest çotanak length was 47.48 mm in the south and as for Tombul variety the highest çotanak length was 49.63 mm in the north, the lowest çotanak length was 46.60 mm in the west. Both in the two hazelnut varieties it was determined that south facing branches had the most fruits and according to average of four directions; at the palaz hazelnut variety double and triple çotanaks occured, at the tombul hazelnut variety triple and quartet çotanaks occured
