    (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.

    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.
