In the 2023 study, conducted in the Hizan District of Bitlis, aimed at determining the biochemical properties of pistachio trees grafted onto Pistacia khinjuk rootstocks, we identified 11 genotypes. Approximately 500 g of fruit were harvested from each genotype when the green fruit peel color started turning red, for use in the analyses. The various parameters were measured in the harvested fruits, including fruit size, yield, percentage of empty fruits, number of fruits per 100 g, splitting rate, moisture, ash, protein, fat, and mineral content. The fruit analyses revealed significant differences among the genotypes. The largest fruits were found in the G5 genotype, while the smallest were in the G9 genotype. Regarding yield, the highest ratio was observed in the G6 genotype with 46.63%, while the lowest was in the G10 genotype with 13.44%. The splitting rate, which varied by genotype, ranged between 0.97% and 41.88%. No statistical differences were observed in moisture and ash content among the genotypes, but protein content ranged from 18.01% to 28.49%, with the highest protein percentage recorded in the G9 genotype at 28.49%. Nutrient element analysis identified nitrogen (N), magnesium (Mg), calcium (Ca), and potassium (K) in the fruits. K emerged as the most abundant nutrient element across genotypes, followed by CA, magnesium (Mg), and sodium (Na). The G3 genotype exhibited the highest levels of potassium, calcium, magnesium, and manganese. In the fatty acid analyses, 9-octadecenoic acid was found to be the most abundant fatty acid, ranging between 40.5% and 66.7% across genotypes. Additionally, other fatty acids such as hexadecanoic acid, 9,12-octadecadienoic acid, and eicosanoic acid were also detected. These results indicated significant differences in the fatty acid content of the genotypes. As a result the pistachio genotypes examined in this study showed notable differences in terms of fruit yield, quality characteristics, and nutritional values. Particularly, G6 and G9 genotypes stood out with high yield and superior fruit qualities.

In present study, the proximate composition, fatty acid profile and mineral content of wild brown trout living in Munzur river (Tunceli/Turkey) were investigated. The average level of protein, lipid, moisture and ash content of muscle of the wild brown trout was calculated to be 17.48, 2.3, 77.8 and 1.5 %, respectively. Thirty fatty acids were identified in this study. Identification of the fatty acid was carried out with gas chromatography-mass spectrometry (GC-MS). The total polyunsaturated fatty acids (PUPA) were found the highest fatty acid followed by that of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). Docosahexaenoic acid (DHA, C22:6n3) and eicosapentaenoic acid (EPA, C20:5n3), linolenic acid (LNA, C18:3n3) and linoleic acid (LA, C18:2n6) were found to be predominant fatty acids in PUFAs with the percentages of 11.25, 6.82, 6.30 and 4.88, respectively. The ratio of n3/n6 and DHA /EPA was calculated to be 4.55 and 1.65, respectively. Twelve elements were determined in this study. Determination of elements was performed with ICP-AES. P and K were the predominant element among the minerals analyzed and calculated to be 1305.56-2967.06 and 1908.68-1220.10 mg kg(-1) in muscle-skin of the wild brown trout, respectively.
