Turkey grows around 100 fruit species and this number is increasing year by year with new introduction. The country is represented by 3 persimmon species, Diospyros kaki, Diospyros lotus and Diospyros oleifera. Among them, Diospyros oleifera can be seen only in the Mediterranean region in Turkey. Northern Anatolia is the center of wild grown Diospyros lotus which is used as dried fruits in this region. Persimmon production, mainly in the subtropical region in Turkey, has expanded rapidly in the past 10 years and reached around 20,000 tonnes. PERSIMMON CULTIVATION IN TURKEY The cultivation of persimmon in a commercial scale in Turkey is newly developed. The persimmon trees are found as scattered population mostly in the Mediterranean, the Black Sea and the Northeastern Anatolia region (Onur, 1990). The production is based mainly on seedlings materials of local astringent types as isolated trees or mixed with other fruit trees for local consumption. More recently several commercial orchards with introduced PCNA cultivars in the southern part have established and after that persimmon production is increased in Turkey, particularly in subtropical areas. The increased amount gave good export opportunities. Domestic consumption in Turkey is also increased. The main factors for this increase are the introduction of new non-astringent cultivars such as 'Fuyu', 'Jiro', 'Izu', increasing awareness on post-harvest storage life of this fruit and advertisement on nutritional properties, particularly high vitamin A, antioxidant phenolic compounds, etc. of persimmon fruits (Celik and Ercisli, 2007; Ercisli et al., 2008). In Turkey, major persimmon producing areas are the Mediterranean, the Black Sea and the Aegean regions, respectively. Turkey is producing around 20,000 tons of persimmons annually and 80% of the total production is obtained from the Mediterranean region. In the Mediterranean region, Hatay province supplies approximately 30% of the total production of Turkey (Anon., 2006). This province also has one of the old persimmon cultivation areas in Turkey (Yildiz, 2005). In Turkey most of the local cultivars have PVNA and PCA characteristics (Onur, 1990; Tuzcu and Seker, 1997). The introduction of cultivars that are higher yielding, early season, PCNA, edible when it is firm, seedless, easily shipped and storaged and red skin colored increased the demand of both domestic consumption and export quantity. The introduction of new cultivars

Identification ofPrunusrootstocks using morphological traits is almost impossible particularly during the dormant season. However, molecular analysis carried out on actively growing shoot tips, leaves or dormant buds provides good opportunity to reliably distinguish rootstocks. In this study, DNA was extracted from the leaves of a total of 184 sweet cherry rootstock candidates belonging toP. aviumL.,P. cerasusL.,P. mahalebL. andP. angustifoliaL. previously selected from the north-western part of Turkey. The rootstock candidates were tested with ten simple sequence repeat (SSR) primers, developed for thePrunusgenus. The primers successfully identified all rootstock candidates. The results showed that the number of alleles per locus ranged from 10 (UDAp-401, UCD-CH21 and CPSCT010) to 20 (UCD-CH31) with an average of...

Some selected physico-chemical characteristics such as berry weight, protein, pH, total acidity, soluble solid, reducing sugar, vitamin C, total antioxidant capacity (FRAP assay), total phenolic and total anthocyanins of four pre-selected wild grown European elderberry fruits were investigated. Significant differences on most of the chemical content were detected among the genotypes used. The genotype AR2 had the highest protein content (2.91%), while AR4 had the lowest protein content (2.68%). The genotypes with the highest total antioxidant capacity, total phenolic and total anthocyanin content were AR2 (6.37 mmol/100 g fw; 432 mg GAE/100 g fw and 283 mg cyaniding-3-glucoside/100 g fw). The results showed that European elderberry very rich in terms of health components

The objective of the present study is to determine the antioxidant activity and total phenolic content of 18 selected persimmon genotypes. The genotypes were established in a collection parcel at the Black Sea Agricultural Research Institute, Samsun, Turkey. The beta-carotene bleaching method was used to determine antioxidant activity and the Folin-Ciocalteau colorimetric method to determine total phenolics in persimmon fruits. The total phenolic content in fruits, estimated as gallic acid equivalents, ranged from 15.7 mg/g dry weight for 08 TH 12 to 42.3 mg/g gallic acid equivalent for the 08 TH 10 genotype. The highest antioxidant activity was observed in 08 TH 10 as 91.6%, while the lowest was in 14 TH 01 (51.7%), respectively. The antioxidant activities of butylated hydroxyanisole and butylated hydroxytoluene were 93.4% and 91.8%, respectively. A low correlation (R = 0.711) was obtained between total phenolic content and antioxidant activity among genotypes. The results indicate that antioxidant activity in persimmon fruits is strongly affected by genotype.

International Union for the Protection of New Varieties of Plants criteria were used for morphological evaluation, which did not clearly separate these rootstocks. We tested 47 random decamer primers for random amplified polymorphic DNA analysis; 15 of them gave reproducible polymorphic patterns, yielding 109 bands, which showed 78% polymorphism. Based on a dendrogram obtained by unweighted pair group method using arithmetic average analysis, three clusters were obtained. The highest genetic similarities were found between M9 and Vezir-2 (0.670). The random amplified polymorphic DNA markers proved to be more efficient than the standard morphological markers for the identification of rootstocks.

Genetic variation and relationships among 14 wild-grown figs sampled from Coruh Valley in Turkey were characterized by random amplified polymorphic DNA (RAPD). Ninety-eight DNA fragments were scored after amplification of DNA samples with 13 random primers; 70% of the scored bands were polymorphic. Genetic distances between the fig genotypes ranged from 0.21 to 0.62. Genotypes 08-ART-02 and 08-ART-06 were found to be the most closely related, whereas 08-ART-09 and 08-ART-10 were the most distant. The 14 wild-grown genotypes were grouped into six main clusters and one outgroup. We conclude that RAPD analysis is efficient for genotyping wild-grown fig genotypes.

Turkey grows around 100 fruit species and this number is increasing year by year with new introduction. The country is represented by 3 persimmon species, Diospyros kaki, Diospyros lotus and Diospyros oleifera. Among them, Diospyros oleifera can be seen only in the Mediterranean region in Turkey. Northern Anatolia is the center of wild grown Diospyros lotus which is used as dried fruits in this region. Persimmon production, mainly in the subtropical region in Turkey, has expanded rapidly in the past 10 years and reached around 20,000 tonnes. PERSIMMON CULTIVATION IN TURKEY The cultivation of persimmon in a commercial scale in Turkey is newly developed. The persimmon trees are found as scattered population mostly in the Mediterranean, the Black Sea and the Northeastern Anatolia region (Onur, 1990). The production is based mainly on seedlings materials of local astringent types as isolated trees or mixed with other fruit trees for local consumption. More recently several commercial orchards with introduced PCNA cultivars in the southern part have established and after that persimmon production is increased in Turkey, particularly in subtropical areas. The increased amount gave good export opportunities. Domestic consumption in Turkey is also increased. The main factors for this increase are the introduction of new non-astringent cultivars such as 'Fuyu', 'Jiro', 'Izu', increasing awareness on post-harvest storage life of this fruit and advertisement on nutritional properties, particularly high vitamin A, antioxidant phenolic compounds, etc. of persimmon fruits (Celik and Ercisli, 2007; Ercisli et al., 2008). In Turkey, major persimmon producing areas are the Mediterranean, the Black Sea and the Aegean regions, respectively. Turkey is producing around 20,000 tons of persimmons annually and 80% of the total production is obtained from the Mediterranean region. In the Mediterranean region, Hatay province supplies approximately 30% of the total production of Turkey (Anon., 2006). This province also has one of the old persimmon cultivation areas in Turkey (Yildiz, 2005). In Turkey most of the local cultivars have PVNA and PCA characteristics (Onur, 1990; Tuzcu and Seker, 1997). The introduction of cultivars that are higher yielding, early season, PCNA, edible when it is firm, seedless, easily shipped and storaged and red skin colored increased the demand of both domestic consumption and export quantity. The introduction of new cultivars

Identification ofPrunusrootstocks using morphological traits is almost impossible particularly during the dormant season. However, molecular analysis carried out on actively growing shoot tips, leaves or dormant buds provides good opportunity to reliably distinguish rootstocks. In this study, DNA was extracted from the leaves of a total of 184 sweet cherry rootstock candidates belonging toP. aviumL.,P. cerasusL.,P. mahalebL. andP. angustifoliaL. previously selected from the north-western part of Turkey. The rootstock candidates were tested with ten simple sequence repeat (SSR) primers, developed for thePrunusgenus. The primers successfully identified all rootstock candidates. The results showed that the number of alleles per locus ranged from 10 (UDAp-401, UCD-CH21 and CPSCT010) to 20 (UCD-CH31) with an average of...

Some selected physico-chemical characteristics such as berry weight, protein, pH, total acidity, soluble solid, reducing sugar, vitamin C, total antioxidant capacity (FRAP assay), total phenolic and total anthocyanins of four pre-selected wild grown European elderberry fruits were investigated. Significant differences on most of the chemical content were detected among the genotypes used. The genotype AR2 had the highest protein content (2.91%), while AR4 had the lowest protein content (2.68%). The genotypes with the highest total antioxidant capacity, total phenolic and total anthocyanin content were AR2 (6.37 mmol/100 g fw; 432 mg GAE/100 g fw and 283 mg cyaniding-3-glucoside/100 g fw). The results showed that European elderberry very rich in terms of health components

The objective of the present study is to determine the antioxidant activity and total phenolic content of 18 selected persimmon genotypes. The genotypes were established in a collection parcel at the Black Sea Agricultural Research Institute, Samsun, Turkey. The beta-carotene bleaching method was used to determine antioxidant activity and the Folin-Ciocalteau colorimetric method to determine total phenolics in persimmon fruits. The total phenolic content in fruits, estimated as gallic acid equivalents, ranged from 15.7 mg/g dry weight for 08 TH 12 to 42.3 mg/g gallic acid equivalent for the 08 TH 10 genotype. The highest antioxidant activity was observed in 08 TH 10 as 91.6%, while the lowest was in 14 TH 01 (51.7%), respectively. The antioxidant activities of butylated hydroxyanisole and butylated hydroxytoluene were 93.4% and 91.8%, respectively. A low correlation (R = 0.711) was obtained between total phenolic content and antioxidant activity among genotypes. The results indicate that antioxidant activity in persimmon fruits is strongly affected by genotype.

International Union for the Protection of New Varieties of Plants criteria were used for morphological evaluation, which did not clearly separate these rootstocks. We tested 47 random decamer primers for random amplified polymorphic DNA analysis; 15 of them gave reproducible polymorphic patterns, yielding 109 bands, which showed 78% polymorphism. Based on a dendrogram obtained by unweighted pair group method using arithmetic average analysis, three clusters were obtained. The highest genetic similarities were found between M9 and Vezir-2 (0.670). The random amplified polymorphic DNA markers proved to be more efficient than the standard morphological markers for the identification of rootstocks.

Genetic variation and relationships among 14 wild-grown figs sampled from Coruh Valley in Turkey were characterized by random amplified polymorphic DNA (RAPD). Ninety-eight DNA fragments were scored after amplification of DNA samples with 13 random primers; 70% of the scored bands were polymorphic. Genetic distances between the fig genotypes ranged from 0.21 to 0.62. Genotypes 08-ART-02 and 08-ART-06 were found to be the most closely related, whereas 08-ART-09 and 08-ART-10 were the most distant. The 14 wild-grown genotypes were grouped into six main clusters and one outgroup. We conclude that RAPD analysis is efficient for genotyping wild-grown fig genotypes.
