    ABSTRACT: In this study we report on the content of organic acids, sugars and minerals in the pulps of the twelve cherry laurel accessions most commonly consumed in eastern Black Sea Region. Malic acid was the dominant organic acid ranged from 43.27 (CL6) to 54.23 (CL3) mg/100 g fresh weight basis. The dominant sugars were glucose and fructose in the pulps that ranged from 4.83 (CL1) to 5.74 (CL5) mg/100 g and 4.66 (CL3) to 5.53 (CL7) mg/100 g, respectively. The pulp of cherry laurel was shown to be rich in potassium (187–241 mg), phosphorus (26–45 mg), calcium (15–22 mg), magnesium (15–24 mg) and sodium (3.9–6.1 mg) in 100 g fruit pulp. The data may be useful in selecting wild edible fruit species appropriate for incorporation into diets.

    ABSTRACT: Peroxidase plays important roles in many stress-related interactions and catalyzes important reactions in various physiological processes. Since peroxidase played critical roles in the evolution of almond (Prunus dulcis Miller (D.A Webb) syn P. amygdalus Batsch), peroxidase-gene-based analyses may increase the understanding of evolution of this species. Peroxidase gene polymorphism (POGP) markers were used to determine genetic diversity and relationships among 69 Turkish genotypes/cultivars and 27 foreign almond cultivars by using unweighted pair group method with arithmetic mean (UPGMA) analysis. This study is the first evaluation of the use of POGP markers for diversity analysis in almond. Totally, 83 fragments were obtained from eight peroxidase primer pairs, and polymorphism was identified as 94 %. Similarity level among the genotypes ranged between 0.63 and 0.93, and all materials were distinguished. In general, Turkish and foreign genotypes were mixed in clusters since they share a common genetic background and gene migration among the sites. Clusters were not based on geographic regions except for some minor groupings. This study indicated that peroxidase gene markers can be reliably used to determine genetic relationships in almonds.

    ABSTRACT: Autochthonous apple varieties are still keeping their importance in Montenegro and they are valuable resources as human food and an important part of rural landscape. The aim of this study was to study and preserve morphological diversity of 30 autochthonous apple varieties in Montenegro between 2008 and 2010. We found a great variation on blooming period and maturation time among varieties and classified them as very early, early, mid and late for blooming and early, middle, late and very late for maturation. Fruit weight varied in wide range from 40.76 g to 206.74 g and ‘Krupnaja’, ‘Krstovača’ and ‘Babovača’ produced biggest fruits (191.83–206.74 g). Soluble solid content (SSC) varied between 11.0 to 16.1 % among varieties and ‘Borovača’, ‘Aleksandrija’, ‘Krstovača’, ‘Dapsićanka’, ‘Bosnika’, ‘Rebrača’ and ‘Babovača’ had the highest SSC values imply that they can be commercially used in production of spirits, wine, concentrate and jam and also for drying. Based on 3-year average data for 25 properties, UPGMA (Unweighted Pair Group Method with Arithmetic Mean) dendrogram showed a high degree of variability among the studied varieties dividing them into 5 groups and 3 independent accessions.

    ABSTRACT: Zinc (Zn) deficiency is frequently observed in mangoes grown in calcareous soils. Inherent inability of mango to extract sufficient Zn from the soil exacerbates this situation. Therefore, mitigating effects of Zn application was investigated on flowering, fruit setting, yield and quality of mango cv. Samar Bahisht Chaunsa growing in calcareous soils. The experiment consisted of five treatments: control—no Zn, soil application of 50 and 100 g ZnSO4 per tree and foliar application of 0.5 and 1.0 % ZnSO4 solution. Zn was applied twice in the 2nd week of November, 2011 and 3rd week of March, 2012, respectively. The experiment was repeated on the same dates during the next growing season. Zn application significantly increased number of flower panicle, fruits matured panicle, leaf Zn concentrations, fruit size, peel thickness, fruit weights at harvest and after ripening and fruit yield tree, whereas it reduced malformed panicles and early fruit drop. However, flower sex ratio and fruit set remained statistically unaffected. Similarly, fruit quality in terms of total soluble solids, flesh color, aroma, flavor and overall acceptability significantly improved as compared to control. Foliar application mitigated Zn deficiency more effectively than the soil application in calcareous soils.

    ABSTRACT: Xanthan gum (XG) is a polysaccharide produced by Xanthomonas campestris. The aim of the present study was to modify the xanthan by hydrolysis and grafting with acrylamide through microwave irradiation for different time intervals. Pure xanthan was partially hydrolyzed via enzymatic and chemical treatments followed by optional grafting. Proximate composition analysis, moisture content, and carbohydrate, protein, lipid, and fiber contents were determined. The morphological characteristics, structural composition, functional groups, and heat resistance of the crude, hydrolyzed, and grafted gum were evaluated using SEM, XRD, FTIR spectroscopy, and TGA. Morphological studies revealed that xanthan was broken down into smaller fragments as a result of hydrolysis and became somewhat smoother. Thermal analysis studies indicated a larger heat tolerance in the grafted xanthan relative to that of the native and hydrolyzed gums. Xanthan bound to a triamcinolone drug was evaluated in the context of controlled drug release. Controlled drug release correlated well with the exposure time to microwaves used to graft the gum.

    ABSTRACT: In this research, two well-recognized standard grape cultivars, Cabernet Sauvignon and Merlot, together with eight historical autochthonous grapevine cultivars from Eastern Anatolia in Turkey, were genetically characterized by using 12 pairs of simple sequence repeat (SSR) primers in order to evaluate their genetic diversity and relatedness. All of the used SSR primers produced successful amplifications and revealed DNA polymorphisms, which were subsequently utilized to evaluate the genetic relatedness of the grapevine cultivars. Allele richness was implied by the identification of 69 alleles in 8 autochthonous cultivars with a mean value of 5.75 alleles per locus. The average expected heterozygosity and observed heterozygosity were found to be 0.749 and 0.739, respectively. Taking into account the generated alleles, the highest number was recorded in VVC2C3 and VVS2 loci (nine and eight alleles per locus, respectively), whereas the lowest number was recorded in VrZAG83 (three alleles per locus). Two main clusters were produced by using the unweighted pair-group method with arithmetic mean dendrogram constructed on the basis of the SSR data. Only Cabernet Sauvignon and Merlot cultivars were included in the first cluster. The second cluster involved the rest of the autochthonous cultivars. The results obtained during the study illustrated clearly that SSR markers have verified to be an effective tool for fingerprinting grapevine cultivars and carrying out grapevine biodiversity studies. The obtained data are also meaningful references for grapevine domestication.

    ABSTRACT: Turkey ranked third place in the world for chestnut production after China and South Korea and the country has unique chestnut forests including valuable and diverse chestnut genotypes. This study was conducted to select superior chestnut genotypes within seedling populations found in natural wild grown chestnut forest located in Isparta province in Turkey during 2010–2011 years. A total of 2500 wild grown chestnut trees were examined on the field first year and among them the most promising 22 genotypes were chosen according to relatively high yield capacity, earliness, tolerance to chestnut blight (Cryphonectria parasitica), ink disease (Phytopthora cambivora), and fruit quality characteristics. The selected 22 genotypes were evaluated for their detailed morphological, phenological and pomological traits in 2010 and 2011. According to average of 2 years, nut weight, the number of nut per kilogram, nut width, nut length, nut height and nut shell thickness of 22 promising genotypes ranged from 10.26 to 22.32 g, 97.47 to 44.80/kg, 26.80 to 42.47, 16.92 to 25.91, 27.74 to 39.73, and 0.26 to 1.01 mm, respectively. The ash, crude protein, and total fat content of kernels were between 0.85 to 1.94, 3.69 to 7.06 and 1.32 to 4.52, respectively. The genotypes were evaluated with weighted ranking method and the highest general quality score was observed in genotypes of IY17, IY01, IY42, IY43 and IY12. © 2015 Northeast Forestry University and Springer-Verlag Berlin Heidelberg

    ABSTRACT: Wild pear (Pyrus eleagnifolia) is a naturally grown species mainly in inner Anatolia and its edible small fruits are traditionally consumed by local peoples and are called “Ahlat” in Turkey. Its seedlings are also used as rootstock for commercial pear cultivars. In this study, we reported first time pomological characteristics and biochemical compositions in fruits of a wide number selected wild pears genotypes (Pyrus eleagnifolia Pall.) from inner Anatolia. The obtained results revealed that there were significant differences among wild pear genotypes for all analyzed parameters. Fruit weight, total phenolics, total acidity and total sugar contents of the fruits varied from 4.71 to 27.09 g, 42.79 to 119.14 mg GAE/100 g, 0.20 to 1.40 g/100 g and 8.36 to 19.31 g/100 g, respectively. Considering these values, it was concluded that naturally grown wild pears of Anatolia with their rich salubrious biochemical compounds could reliably be used as a food source for humans.

    ABSTRACT: The methanolic extract of various parts of Ranunculus glacialis and their fractions were analysed for their antioxidant and antimicrobial activities. Total phenolic and fiavonoid contents of n-hexane, chloroform, ethylacetate and n-butanol fractions were determined by using IIPLC analysis which indicated the presence of appreciable levels of these phytochemicals. It was observed that the methanol extract and aqueous fractions of stem and leaves showed high values of phenolic content. The GC-MS analysis of essential oil and n-hexane extract was carried out to determine the nature of the volatile compounds present in them. Finally, cytotoxicity of the methanolic extract and fractions was assessed by haemolytic activity. The methanolic extract and chloroform fraction showed maximum value of % haemolytic activity. The study reveals the potential of Ranunculuc glacialis as a biologically active plant.

    ABSTRACT: Shape is a crucial physical property of agricultural products and hence is an important parameter for assessing the quality standard. In the present study, shape variations among 17 hazelnut cultivars grown in Turkey were revealed from their digital images using shape descriptors obtained from elliptic Fourier analysis (EFA), which is a shape-based methodology. Subsequently, principal component analysis (PCA) was performed to summarize the variations among the hazelnut cultivars. This was followed by linear discriminant analysis using the first four principal components, representing 93.9 % of the total variance, obtained from the PCA to discriminate the 17 hazelnut cultivars. Estimates of Hotelling's pairwise comparisons from the multivariate analysis based on the shape variables obtained from the EFA revealed ideal shape differences between the hazelnut cultivars. Hierarchical cluster analysis divided the cultivars into six clusters according to their shape characteristics. In addition, size (projected area, length, width, thickness, surface area, geometric mean diameter), shape (shape index, sphericity, roundness, and elongation), and gravimetric (mass and volume) features of the 17 common hazelnut cultivars were also determined via an image processing technique.An analysis of variance was performed to test the differences among these variables in a descriptive method. We found that EFA provided excellent discrimination between the hazelnut cultivars with respect to their shape features.

    ABSTRACT: Abstract: Cadmium (Cd) is well known as one of the most toxic metals affecting the environment and can severely restrict plant growth and development. In this study, Cd toxicities were studied in strawberry cv. Camarosa using pot experiment. Chlorophyll and malondialdehyde (MDA) contents, catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX) activities and mineral nutrient concentrations were investigated in both roots and leaves of strawberry plant after exposure Cd. Cd content in both roots and leaves was increased with the application of increasing concentrations of Cd. We found higher Cd concentration in roots rather than in leaves. Chlorophyll a and b was decreased in leaves but MDA significantly increased under increased Cd concentration treatments in both roots and leaves. SOD and CAT activities was also increased with the increase Cd concentrations. K, Mn and Mg concentrations were found higher in leaves than roots under Cd stress. In general, increased Cd treatments increased K, Mg, Fe, Ca, Cu and Zn concentration in both roots and leaves. Excessive Cd treatments reduced chlorophyll contents, increased antioxidant enzyme activities and changes in plant nutrition concentrations in both roots and leaves. The results presented in this work suggested that Cd treatments have negative effect on chlorophyll content and nearly decreased 30% of plant growth in strawberry. Strawberry roots accumulated higher Cd than leaves. We found that MDA and antioxidant enzyme (CAT, SOD and APX) contents may have considered a good indicator in determining Cd tolerance in strawberry plant.

    ABSTRACT: Fruit size has special importance for small-fruited early maturing cherry cultivars. In this study the effects of pre-harvest benzyladenine (BA) and BA plus gibberellin (GA) applications on fruit size and quality of ‘Noir de Guben’ sweet cherry (Prunus avium) were evaluated. ‘Noir de Guben’ trees were sprayed to run off with BA (50, 100 and 150 ppm) and BA + GA4+7 (12.5, 25, and 50 ppm) at straw-yellow color stage of the fruit. Fruit treated with BA (50, 100 and 150 ppm) and BA + GA4+7 (25 and 50 ppm) were significantly heavier and larger than the control. BA and BA + GA4+7 applications did not affect fruit firmness and fruit pH. 50 ppm BA-treated fruit had higher SSC (Soluble Solid Content) than control fruit. Excluding 25 ppm BA treatments, all treated fruit had higher acidity than the control fruit. BA and BA + GA4+7 applications delayed skin color development of the treated fruit. ‘Noir de Guben’ trees treated with the optimum concentrations of BA (150 ppm) and BA + GA4+7 (50 ppm) yielded fruit with 16.84 and 10.6 % greater weight, respectively.

    ABSTRACT: Phytochemical profiles and antioxidant activity of four historical grape accessions (‘Kuzu Kuyrugu’, ‘Miskali’, ‘Erkek miskali’, and ‘Kirmizi Kismisi’) grown in Igdir province located in Eastern Anatolia Region of Turkey were examined. Levels of vitamin C, organic acids (citric acid, tartaric acid, malic acid, succinic acid, fumaric acid), sugars (fructose, glucose), phenolic acids (catechin, rutin, quercetin, chlorogenic acid, ferulic acid, o-coumaric acid, p-coumaric acid, caffeic acid, syringic acid, vanillic acid, and gallic acid), and antioxidant capacity (Trolox Equivalent Antioxidant capacity, TEAC assay) were determined. Accession was found to be important source of variation for all the parameters identified above (P<0.01). Among the grape accessions analyzed, ‘Kuzu Kuyrugu’ had the predominant vitamin C (47.19 mg/100 g), chlorogenic acid (2.687 mg/L), ferulic acid (1.303 mg/L), o-coumaric acid (1.317 mg/L), and syringic acid content (1.687 mg/L). The highest citric acid (55.360 mg/L), fructose (10.36 g/100g), glucose (11.51 g/100g), and catechin (1.353 mg/L) were recorded in ‘Miskali’ genotype. ‘Kirmizi Kismisi’ was determined to be the accession with the highest tartaric acid (21.29 mg/L), succinic acid (0.94 mg/L), and caffeic acid (2.137 mg/L) levels. ‘Erkek Miskali’ accession produced the paramount contents for fumaric acid (0.42 mg/L), rutin (2.477 mg/L), quercetin (0.447 mg/L), and vanillic acid (0.313 mg/L). The investigated grape genotypes showed notable levels of sugars, organic acids and phenolic compounds. These accessions could be valuable in breeding programs for improving grape quality and nutrition, as well as enhancing commercial worth and production of the grapes in Igdir province of Turkey.

    ABSTRACT: Background The Eurasian grapevine (Vitis vinifera L.) is the most widely cultivated and economically important horticultural crop in the world. As a one of the origin area, Anatolia played an important role in the diversification and spread of the cultivated form V. vinifera ssp. vinifera cultivars and also the wild form V. vinifera ssp. sylvestris ecotypes. Although several biodiversity studies have been conducted with local cultivars in different regions of Anatolia, no information has been reported so far on the biochemical (organic acids, sugars, phenolic acids, vitamin C) and antioxidant diversity of local historical table V. vinifera cultivars grown in Igdir province. In this work, we studied these traits in nine local table grape cultivars viz. ‘Beyaz Kismis’ (synonym name of Sultanina or Thompson seedless), ‘Askeri’, ‘El Hakki’, ‘Kirmizi Kismis’, ‘Inek Emcegi’, ‘Hacabas’, ‘Kerim Gandi’, ‘Yazen Dayi’, and ‘Miskali’ spread in the Igdir province of Eastern part of Turkey. Results Variability of all studied parameters is strongly influenced by cultivars (P < 0.01). Among the cultivars investigated, ‘Miskali’ showed the highest citric acid content (0.959 g/l) while ‘Kirmizi Kismis’ produced predominant contents in tartaric acid (12.71 g/l). The highest glucose (16.47 g/100 g) and fructose (15.55 g/100 g) contents were provided with ‘Beyaz Kismis’. ‘Kirmizi Kismis’ cultivar had also the highest quercetin (0.55 mg/l), o-coumaric acid (1.90 mg/l), and caffeic acid (2.73 mg/l) content. The highest ferulic acid (0.94 mg/l), and syringic acid (2.00 mg/l) contents were observed with ‘Beyaz Kismis’ cultivar. The highest antioxidant capacity was obtained as 9.09 μmol TE g-1 from ‘Inek Emcegi’ in TEAC (Trolox equivalent Antioxidant Capacity) assay. ‘Hacabas’ cultivar had the highest vitamin C content of 35.74 mg/100 g. Conclusions Present results illustrated that the historical table grape cultivars grown in Igdir province of Eastern part of Turkey contained diverse and valuable sugars, organic acids, phenolic acids, Vitamin C values and demonstrated important antioxidant capacity for human health benefits. Further preservation and use of this gene pool will be helpful to avoid genetic erosion and to promote continued agriculture in the region.
