Investigation of the Pomological Characteristics of Selected 'Tombul' Hazelnut Clones in the Bulancak Area of Giresun Province

7th International Congress on Hazelnut -- OCT 31, 2009 -- Viterbo, ITALYWOS: 000305695500004This study was carried out to determine some nut and kernel characteristics of clones of 'Tombul' hazelnut cultivars grown in villages of Bulancak in the province of Giresun in the years 2005-2006. The clones had nut weights between 1.76-2.40 g, kernel weights between 0.95-1.16 g, shell thickness between 0.67-1.20 mm, nut number per cluster between 3.08-4.15 number/cluster, nut size between 16.34-18.57 mm, kernel size between 12.86-13.62 mm and kernel cavity between 1.54-2.69 mm. The study found that nut number per cluster increased as nut size and shell thickness decreased but kernel percentage increased. Concerning the decrease of nut number per cluster, nut size and shell thickness increased but kernel percentage decreased
