Twelve traits were investigated in trees of three cultivars ranging from 10 to 55 years of age. The traits were nut weight, nut size, shell thickness, kernel weight, kernel size, internal cavity, kernel percentage, leaf area, petiole length, petiole thickness, average pellicle removal percentage and full pellicle removal percentage (100 % blanching). Trees were of 'Tombul', 'Palaz' and 'Sivri' in Giresun province in 1999. Significant differences were observed among orchards of different ages for three traits (leaf area, petiole length and petiole thickness) in 'Tombul', for three traits (nut weight, nut size and full pellicle removal percentage) in 'Palaz', and for five traits (nut weight, nut size, kernel weight, kernel size and leaf area) in 'Sivri'.
