    (Elsevier, 2020) Ozrenk, Koray; Ilhan, Gulce; Sagbas, Halil Ibrahim; Karatas, Neva; Ercisli, Sezai; Colak, Aysen Melda
    In this study, a comprehensive morphological and biochemical characterization of 14 European Cranberrybush (Viburnum opulus L.) genotypes that were collected from Gumushane province of Turkey is provided. Additionally, their potentials as cultivar candidate, natural antioxidants, colorants and ingredients were exploited. Yield per bush, fruit weight, number of fruits per raceme and number of racemes per bush were ranged from 4.7 kg to 6.2 kg; 0.53 to 0.86 g; 34.4-53.1 and 119-307 among genotypes indicating high diversity. The majority of genotypes (8) had red fruit skin color and rest of the genotypes had equally light red and dark red fruit skin color. European Cranberrybush fruits had medium level vitamin C content (28 - 43 mg per 100 g fresh fruit) and the genotypes had SSC (Soluble Solid Content) between 10.40 and 12.20 %. Crude protein and crude cellulose of the genotypes varied from 5.67 to 6.71 (%) and 16.6-18.7 (%), respectively. Total phenol and total anthocyanin content ranged from 696 to 830 mg gallic acid equivalent per 100 g fresh weight and 27.6-54.3 mg per 100 g fresh fruit expressed cyanidin-3-glucoside. Antioxidant activity were found between 27.67 and 35.65 mu mol trolox equivalents per g fresh fruit based on FRAP (Ferric Reducing Ability of Plasma) assay. Total lipid content ranged from 10.3-13.3 (%) and oleic acid was dominant fatty acids for all genotypes (57.3-70.4). Local genotypes are found to be promising for further valorization through horticultural characteristics and novel antioxidants, colorants and ingredients.

    (Serbian Genetics Soc, 2015) Pinar, Hasan; Ercisli, Sezai; Unlu, Mustafa; Bircan, Mustafa; Uzun, Aydin; Keles, Davut; Baysal, Filiz
    More recently the use of different molecular markers in fruit species to determine particularly genetic diversity, genetic relationships and cultivar identification has been gained more importance. In the study, 13 randomly amplified polimorfic DNA (RAPD) and 4 inter-simple sequence repeat (ISSR) markers were used to evaluate genetic relationships among 95 almong accessions (26 foreign cultivars and 69 national cultivars and selections). The all plant material found in Almond Germplasm Repository in Gaziantep, Turkey. Both RAPD and ISSR markers distinguished the almond cultivars and selections in various levels. 17 RAPD and ISSR markers yielded a total of 73 scorable bands, which 51 are polymorphic. The two marker system exhibited variation with regard to average band sizes and polymorphism ratio. The average polymorphism was higher in ISSR (88%) compared to RAPD (74%). RAPD and ISSR marker systems were found to be useful for determining genetic diversity among almong genotypes and cultivars. Combining of two dendrograms obtained through these markers show different clustering of 96 almond specimens without geographical isolation. These results supported that almonds in Turkey indicated considerable genetic diversity.

    Leaf Plant Nutrient Content and Sapling Growth of 'Transvalia' Peach Variety Grafted On Prunus Rootstocks
    (Springer, 2024) Ugur, Remzi; Gundesli, Muhammet Ali; Ercisli, Sezai; Ilhan, Gulce; Atli, Halit Seyfettin; Durul, Melekber Sulusoglu; Eyduran, Sadiye Peral
    In peach cultivation, there is an increasing interest in breeding rootstock suitable for intensive planting and for use in calcareous and poor soils. This study was carried out to test the performance of some promising Prunus rootstocks for 'Transvalia' peach variety. A total of 16 rootstocks obtained by interspecies hybridization from different origins were used for 'Transvalia' peach variety. Rootstock diameter, scion diameter, sapling height, rootstock scion ratio, leaf chlorophyll contents and leaf plant nutrient contents were analyzed. Results showed that the level of the majority of macro- and micro-elements was found to be sufficient. Leaf chlorophyll contents of 'Transvalia' peach cultivar grafted on stronger rootstocks such as GN-22, FG-58 and NGF-14 were found to be the highest. It has been determined that FG-16 rootstock is 40% more dwarf in terms of seedling growth strength compared to GN-22 rootstock in the Mediterranean climate zone. There were significant differences between rootstocks in terms of scion leaf chylorphyll content (SPAD values). The highest leaf chlorophyll contents were found in 'Transvalia' peach variety grafted on GN-22 (48.22), FG-58 (47.75) and NGF-14 (47.14), which are strong rootstocks. No correlation was found between growth strength and leaf plant nutrients. However, it has been determined that strong growing rootstocks can give positive results in lower quality soils.

    MOLECULAR CHARACTERIZATION AND GENETIC RELATIONSHIPS OF WILD APRICOTS (PRUNUS ARMENIACA L.) FROM TURKEY USING SSR MARKERS
    (Publ House Bulgarian Acad Sci, 2020) Ozrenk, Koray; Ozkan, Gursel; Akin, Meleksen; Orhan, Emine; Eyduran, Sadiye Peral; Ercisli, Sezai
    In the present study we used a total of 29 wild apricot genotypes sampled from 3 regions (Erzincan, Coruh valley, and Aras valley) which were evaluated by means of simple sequence repeat (SSR) markers. In total, 16 simple sequence repeat (SSR) loci were used and 98 alleles were revealed with a mean number of 6.13 alleles per locus and mean polymorphic information content (PIC) of 0.66 showing a high genetic diversity of Turkish wild apricots. A larger expected heterozygote than the observed was found in the analyzed genotypes. Clustering of individual accessions based on UPGMA dendrogram separated accessions into three major clusters according to their geographic origin and indicating high variability among genotypes. The information obtained in this study implies that the studied genotypes were distant from each other and can be used for apricot breeding strategies and for the management and the conservation of Turkish apricot germplasm.

    Organic acids, sugars, vitamin C content and some pomological characteristics of eleven hawthorn species (Crataegus spp.) from Turkey
    (Soc Biolgia Chile, 2014) Gundogdu, Muttalip; Ozrenk, Koray; Ercisli, Sezai; Kan, Tuncay; Kodad, Ossama; Hegedus, Attila
    Background: The Hawthorn (Crateagus sp.) mostly occurs around the temperate region of the world with a high number of species, producing a fruit with numerous beneficial effects for human health. The aim of the study was to determine organic acid and sugar contents in the fruit of a number of hawthorn species grown in Erzincan province of Turkey. Results: Citric acid was the predominant organic acid in all hawthorn species and C. pseudoheterophylla had the highest citric acid content (23.688 g/100 g). There were not statistically significant differences among hawthorn species (except C. atrosanguinea Pojark) in terms of fumaric acid content. C. pontica C. Koch had a higher content of vitamin C (9.418 mg/100 g) compared to other species. Fructose was the predominant sugar component in all species and C. monogyna subsp. monogyna Joiq had the highest fructose content (18.378 g/100 g). Conclusions: The high fruit quality of the studied species indicates the importance of this fruit in human nutrition as a natural source. The study revealed that there were differences in terms of fruit characteristics among hawthorn species and thus better quality hawthorn genotypes can be selected within the species. Hence, this study is considered to be a valuable reference for forthcoming studies. The high fruit quality of the studied species indicates the importance of this fruit in human nutrition as a natural source.

    (Serbian Genetics Soc, 2023) Ozrenk, Koray; Tas, Akgul; Gundogdu, Muttalip; Keskin, Nurhan; Ercisli, Sezai
    Turkey has a very rich flora due to diverse climatic and topographic conditions within the country. Cornelian cherry (Cornus mas L.) is an important wild edible fruits and widely distributed in Turkey and well known for its fruit antioxidants and nutrients. In this study, phytochemical content in fruits of a number of Cornelian cherry genotypes in Erzincan region were determined. The biochemical analysis included organic acids, sugars, vitamin C, antioxidant and individual phenolic compounds. In the study, organic acid content was between 253.09 mg/100 g and 112.50 mg/100 g. Vitamin C content varied between 115.85 mg/100g and 43.77 mg/100 g. Likewise, the sugar content of Cornelian cherry fruits varied from 6.17 g/100 g to 4.06 g/100 g. When the antioxidant content was examined, the highest antioxidant was 980.91 limol TE/g fresh weight (FW) base and the lowest was 490.38 limol TE/g FW. In the genotypes examined, gallic acid was determined as the highest among the individual phenolic compounds, while the individual phenolic amounts ranged from 38.93 mg/100 g FW to 4.31 mg/100 g FW. As a result of the study, it was determined that Cornelian cherry fruits are very rich in vitamin C and other phytochemicals and as a result of this examination, 24ER04 and 24ER08 genotypes came to the fore.
