(Academic Press inc Elsevier Science, 2006) Seferoglu, S.; Seferoglu, H. G.; Tekintas, F. E.; Balta, F.
Uzun is one of the major pistachio varieties of Turkey. In this study conducted in seven different locations of the Buyuk Menderes River Basin of western Anatolia (Turkey), some biochemical and fruit quality traits were assessed. Biochemical contents such as protein, fat, dry matter and ash contents, unsaturated and saturated fatty acid compositions in this variety were determined based on locations over a period of 2 years. Biochemical composition such as protein, fat, dry matter and ash contents differed significantly by locations (P < 0.05). The mean protein content ranged from 23.2%-31.7%. The mean fat content varied from 46.8%-66.5%. The unsaturated fatty acid composition as percent showed averagely a range of 72.2-75.0 for oleic acid, 11.2-13.1 for linoleic acid, 0.27-0.34 for linolenic acid, 0.21-0.28 for arachidic acid, 0.40-0.43 for gadoleic acid and 0.11-0.14 for behenic acid depending on locations. The saturated fatty acids as percent composed a range of 0.06-0.08 in myristic acid, 8.25-9.52 in palmitic acid, 0.59-0.76 in palmitoleic acid, 0.05-0.07 in heptadecanoic acid and 2.36-3.71 in stearic acid. The contents of saturated fatty acids (palmitic, palmitoleic and stearic) except for myrictic and heptadecanoic acid, and all unsaturated fatty acids (oleic, linoleic, linolenic, arachidic and behenic) except for gadoleic acid also differed significantly by locations (P < 0.05). Consequently, the biochemical composition was significantly affected by different growing areas. (c) 2006 Elsevier Inc. All rights reserved.
Fatty Acid Composition Affected by Kernel Weight in Almond [Prunus Dulcis (Mill.) D.a.!webb.] Genetic Resources
(Academic Press inc Elsevier Science, 2007) Askin, M. A.; Balta, M. F.; Tekintas, F. E.; Kazankaya, A.; Balta, F.
Twenty-six almond [Prunus dulcis (Miller) D.A. Webb.] genotypes were selected from Elazig province located on eastern Anatolia region of Turkey in 1999 and 2001. Their fatty acid compositions were determined in relation to kernel weight and shell thickness. They had a range of 0.50-1.34 g in kernel weight, 1.96-4.66 mm in shell thickness, 16.07-31.46% in protein content and 25.19-60.77% in oil content. In addition, their kernels contained 5.46-15.78% palmitic acid, 0.36-2.52 palmitoleic acid, 0.80-3.83% stearic acid, 50.41-81.20% oleic acid and 6.21-37.13% linoleic acid. Linolenic acid in two genotypes and myristic acid in six genotypes were detected. In genotypes classified according to their kernel weights, relationships among fatty acid contents, fat content, kernel weight and shell thickness were also studied using correlation coefficients and regression analyses. Findings revealed that contents of palmitic acid, stearic acid, oleic acid and linoleic acid were significantly influenced by kernel weight. Contents of palmitic acid and stearic acid were negatively correlated with shell thickness, and oleic acid content was positively correlated with shell thickness. (c) 2006 Elsevier Inc.
