Some Fruit Properties and Macro-Micro Element Contents of Selected Walnuts (Juglans Regia L.) From Batman Region

Abstract

This study was carried out to determine some physical and chemical properties of 27 walnut genotypes selected from Kozluk and Sason regions of Batman. In the study, fruit thicknesses, fruit widths, fruit height, shell thicknesses, nut weights, kernel weights, kernel ratios were varied from 25.99-37 to 19 mm, 27.25 to 35.29 mm, 29.64 to 50.69 mm, 1.11 to 2.55 mm, 8.28 to 17.45 g, 3.59 to 7.74, 36.00% to 58.25%, respectively. Inner colors was determined as very light coloured in 13 genotypes, light coloured in 10 genotypes and medium coloured in 4 genotypes. The protein contents of selected genotypes were found between 12.15% and 18.30%, oil content between 53.25% and 68.70 %, moisture contents between 1.87 and 3.60 %, ash contents between 1.30% and 2.96% and their average values were 15.74 %, 62.92 %, 2.69 % and 1.83 %, respectively. Average of macro element contents of genotypes were found 2.35% N; 285.64 mg P; 406.23 mg K; 315.83 mg Mg; 226.30 mg Ca; and 187.71 mg S. Average micro element contents were determined Na 2.05 mg, Fe 2.51 mg, Mn 2.86 mg, Zn 2.42 mg, Cu 1.78 mg in 100 g of kernel fruit. © 2020, Centenary University. All rights reserved.
