Öğe Agro-morphological and biochemical characterization of wild prunus spinosa l. subsp. dasyphylla (schur) domin genotypes naturally grown in western black sea region of Turkey(Mdpi, 2020) Berk, Selma Kuru; Taş, Akgül; Orman, Erdal; Gündoğdu, Müttalip; Necas, Tomas; Ondrasek, Ivo; Karataş, NevaIn this study, agro-morphological, sensory and biochemical characteristics of 23 plum genotypes belonging to Prunus spinosa L. subsp. dasyphylla (Schur) Domin growing wild in the West Black Sea Region in Turkey were investigated. Agro-morphological, sensory and biochemical properties of genotypes were highly different from each other. Principal component analysis was performed to determine the correlation between these properties and genotypes. The variation in the study was determined to be 63.5% in agro-morphological properties, 53.8% in organic acids and 46% in phenolic compounds. In terms of fruit weight, 14BLM08 genotype (38.42 g) was determined to be superior to other genotypes. The fruit firmness value, which is important in the storage of fruits, was recorded as the highest in the 14BLM14 genotype (9.07 kg/cm(2)). Chlorogenic acid was higher than the other phenolic compounds and the highest value was obtained in the 14BLM20 (11.45 mg/kg) genotype. It was recorded that the value of malic acid, which is the major organic acid of the plums, varied between 269.65-1294.64 mg/100 g. Genotypes showed diverse vitamin C content, and the highest value was found in the 14BLM18 genotype as 54.42 mg/100g. Each genotype showed superiority according to the type of traits, and thus breeders may have used these genotypes as the superior ones for specific plum breeding purposes. In addition, these genotypes could be satisfactorily used in domestication.Öğe Change in biochemical content of strawberry during shelf life with growth regulator treatments(Springer, 2023) Berk, Selma Kuru; Orman, Erdal; Koçoğlu, Selma Tuna; Gündoğdu, MüttalipThe aim of this study was to determine the changes during shelf life in the organic acid and phenolic components of strawberry fruit ('Albion' cv.) treated with methyl jasmonate (MeJA) and 1-methylcyclopropene (1-MCP). Fruits were kept in plastic perforated containers for 3 and 5 days under room conditions. It was determined that vitamin C content decreased on day 3 in all treatments (from 22.35 to 5.27 mg 100 g(-1)), but increased on day 5 with MeJA + 1-MCP treatment. The highest citric acid level was measured as 1468.89 mg 100 g(-1) on day 3 (control) and as 1423.68 mg 100 g(-1) on day 5 (1-MCP). It was seen that phenolic compound content generally decreased with MeJA and 1-MCP interaction. Treatment with 0.25-mM MeJA increased the amount of catechin on days 3 and 5 (35.679 and 27.574 mg 100 g(-1), respectively). In addition, during shelf life, organic acid content generally increased, while phenolic compound content decreased with treatments. It was observed that the strawberry fruit quality varied according to treatments during the shelf life period.Öğe Diversity in phenolic compounds, biochemical and pomological characteristics of Arbutus unedo fruits(Polish Soc Horticultural Sci, 2018) Gündoğdu, Müttalip; Ercişli, Sezai; Canan, İhsan; Orman, Erdal; Sameeullah, MuhammadStrawberry trees (Arbutus unedo L.) are naturally grown in particular Black Sea and Mediterranean regions of Turkey with great diversity due to continuous seed propagation for centuries. The trees differ in terms of most of the horticultural characteristics. We investigated the phenolic compounds and the biochemical and pomological characteristics of the fruits of eight strawberry tree selections naturally grown in the western part of Turkey. Significant differences were found among the genotypes in terms of their phenolic compounds and their biochemical and pomological characteristics. Among soluble sugars, fructose (11.63 g 100 g(-1)) was the dominant sugar, followed by glucose (6.10 g 100 g(-1)) and sucrose (1.44 g 100 g(-1)) for all the genotypes. Positive correlation was found between fruit weight and soluble sugar content. Malic acid was the major organic acid (0.67-2.33 g 100 g(-1)), and the second major organic acid in strawberry tree fruits was citric acid (0.25-0.87 g 100 g(-1)). Vitamin C content was an average of 56.22 g 100 g(-1) for the eight genotypes. Among phenolic compounds, gallic acid was dominant (1.62-7.29 mg 100 g(-1)), followed by chlorogenic acid (1.23-3.14 mg 100 g(-1)), on an average basis.Öğe Fruit quality characteristics of service tree (Sorbus domestica L.) genotypes(American Chemical Society, 2023) Taş, Akgül; Gündoğdu, Müttalip; Ercişli, Sezai; Orman, Erdal; Çelik, Kenan; Marc, Romina AlinaIn this study, agro-morphological properties, phenoliccompounds,and organic acid contents in the fruits of service tree (Sorbus domestica L.) genotypes naturally grown inTu''rkiye (Bolu) were determined. The fruit weights of genotypeswere found to be quite variable, ranging from 5.42 g (14MR05) to 12.54g (14MR07). The highest L*, a*,and b* fruit external color values were found tobe 34.65 (14MR04), 10.48 (14MR09), and 9.10 (14MR08), respectively.The highest chroma and hue values were recorded as 12.87 (14MR09)and 49.07 (14MR04), respectively. 14MR03 and 14MR08 genotypes exhibitedthe highest amount of soluble solid content and titratable acidity(TA) as 20.58 and 1.55%, respectively. The pH value was found to bein the range of 3.98 (14MR010)-4.32 (14MR04). Chlorogenic acid(14MR10, 48.49 mg/100 g), ferulic acid (14MR10, 36.93 mg/100 g), andrutin (14MR05, 36.95 mg/100 g) were predominant phenolic acids observedin the fruits of service tree genotypes. The predominant organic acidin all fruit samples was malic acid (14MR07, 34.14 g/kg fresh weightbasis), and the highest quantity of vitamin C was detected at 95.83mg/100 g in genotype 14MR02. Principal component analyses (%) wereperformed to determine the correlation between the morphological-physicochemical(60.6%) and biochemical characteristics of genotypes (phenolic compounds:54.3%; organic acids and vitamin C: 79.9%). It was determined thatmeasured genotypes were important genetic resources in terms of nutritionalvalue.Öğe Influence of pre-harvest gibberellic acid and post-harvest 1-methyl cyclopropane treatments on phenolic compounds, vitamin c and organic acid contents during the shelf life of strawberry fruits(Mdpi, 2021) Taş, Akgül; Berk, Selma Kuru; Orman, Erdal; Gündoğdu, Müttalip; Ercişli, Sezai; Karataş, Neva; Jurikova, TundeIn recent years, significant portions of the fresh fruits and vegetables produced worldwide have been decaying before reaching the consumer because of insufficient preservation after harvest. In this direction, we carried the study out to investigate the effect of gibberellic acid (GA(3)) and 1-methyl cyclopropane (1-MCP) applications on phenolic compounds and organic acid contents of the strawberry fruits (cv. Albion) during shelf-life. Gibberellic acid treatments, which prepared in two different concentrations (50 and 100 ppm), were performed by spraying the leaves before harvest. 1-methyl cyclopropane applied after harvest. The results of the study showed a greater decrease in organic acids (except oxalic and succinic acid) in Gibberellic acid-applied fruits during shelf-life. Citric acid was recorded as the most abundant organic acid in the control group. In phenolic compounds, gallic acid (15.22 mg 100 g(-1)) and ellagic acid (9.38 mg 100 g(-1)) were recorded as the highest phenolic compounds on the third day. 1-MCP and GA(3) (50 ppm) + 1-MCP treatment reduced the breakdown of vitamin C during the shelf-life of strawberry fruits compared to the control group. As a result, phenolic compounds, vitamin C, and organic acids decreased during the shelf-life, and 1-MCP applications slowed down the breakdown of these compounds.Öğe Sustainable mulberry (Morus nigra L., Morus alba L. and Morus rubra L.) production in Eastern Turkey(MOPI, 2021) Can, Ahmet; Kazankaya, Ahmet; Orman, Erdal; Gündoğdu, Müttalip; Ercişli, Sezai; Choudhary, Ravish; Karunakaran, RohiniIn this study, a total of 55 wild-grown mulberry landraces belonging to Morus alba L., Morus rubra L., and Morus nigra L. species (Rosales order, Moraceae family, Morus L. genus) were sampled around the Van Lake basin, and some fruit characteristics were determined. All landraces are naturally grown in the Lake Van basin under pesticide-free conditions. As fruit character, phenolic compounds (gallic acid, catechin, quercetin, protocatechuic acid, vanillic acid, rutin, chlorogenic acid, caffeic acid, syringic acid, p-coumaric acid, ferulic acid, and phlorizin) and organic acids (malic acid, citric acid, tartaric acid, succinic acid, fumaric acid and ascorbic acid) were determined. Principal component analysis (PCA) was performed to determine the correlation between mulberry species in terms of biochemical compounds. As a result of PCA-biplot analysis, two variations were sufficient to explain the correlation between phenolic compounds and organic acids. This ratio reveals that mulberry species are separated with sharp boundaries in terms of biochemical compounds. Chlorogenic acid and rutin content were high in all mulberry landraces. The highest chlorogenic acid content was detected in landrace 65VN03 belonging to M. rubra (3.778 mg/g), 65GV12 belonging to M. nigra (3.526 mg/g), 13AD08 belonging to M. rubra (2.461 mg/g), and 13AH02 belonging to M. rubra (6.246 mg/g) landraces. In terms of organic acid content, malic acid was the dominant organic acid for genotypes. The rich bioactive compounds make M. alba, M. rubra, and M. nigra landraces as cultivar candidates for breeding purposes. It is a valuable source of bioactive agents that may have prevented humans from oxidative-stress-related diseases.
