Öğe COMPARISON OF POLLEN PRODUCTION AND QUALITY CHARACTERISTICS OF CULTIVATED AND WILD ALMOND SPECIES(Inst Investigaciones Agropecuarias, 2011) Bayazit, Safder; Caliskan, Oguzhan; Imrak, BurhanettinThere are several wild almond species in Turkey included Amygdalus orientalis (Mill.), Amygdalus turcomanica (Lincz.), Amygdalus fenzliana (Fritsch) Lipsky, Amygdalus trichamygdalus (Hand.-Mazz.) Woronow, Amygdalus arabica (Olivier), and Amygdalus webbii (Spach). These species offer a great value for the almond improvement; we studied the pollen viability, germination ratio and pollen yield for seven genotypes of A. orientalis, seven genotypes of A. turcomanica all growing under natural conditions in Southeastern Anatolia (Gaziantep and Sanliurfa provinces, Turkey). Almond cultivars (Prunus dulcis [Mill.] D. A. Webb) obtained from Pozanti Agricultural Experimental Station, Cukurova University, were also used in the experiment. The pollen viabilities of various almond genotypes were determined by 2,3,5-triphenyltetrazolium chloride (TTC) and fluorescein diacetate (FDA) tests. At the end, pollen germination ratios were established according to Petri dishes method in vitro conditions (1% agar + 0, 10, 15 and 20% sucrose) while pollen yield was estimated with hemacytometric methods. The results indicated that pollen viability ratios were close to each other in both methods for the genotypes A. orientalis and A. turcomanica. Pollen germination ratios were found to be dependent on the sucrose content as well as on the genotypes used. The pollen of almond cultivars showed similar germination ratios in all of the sucrose concentrations while those pollens of A. orientalis and A. turcomanica genotypes displayed higher germination ratios in 10% sucrose. The number of anthers in one flower was higher in cultivars whereas the number of pollen grains was lower in other almond species. While the number of pollen grains in one flower was relatively high in A. orientalis genotypes, pollen quality was high in all the three species under research. The results suggested that these two species, namely A. orientalis and A. turcomanica could be employed for future almond breeding programs.Öğe Determination of Pollen Production and Quality attributes of some Almond Cultivars (Prunus dulcis) and Selected Wild Almond (Amygdalus orientalis) Genotypes(Friends Science Publ, 2012) Bayazit, Safder; Imrak, Burhanettin; Caliskan, OguzhanThis study was carried out to establish pollen production, viability and germination ratios for five almond genotypes of Amygdalus orientalis Mill. (Orientalis 5, Orientalis 6, Orientalis 7, Orientalis 9 & Orientalis 10) and four cultivars of Prunus dulcis Mill., (Nonpareil, Texas, Ferragnes & Ferraduel). For determination of pollen viability of selected almond genotypes, 2.3.5 Triphenyltetrazolium chloride and Fluorescent diacetat tests were made. Pollen germination ratios in vitro conditions were determined with petri dishes methods. For A. orientalis genotypes, pollen viability ratios according to the TTC test were found to be 61.80% and 72.88% in 2006 and 2007, respectively whereas the same ratios according to the FDA test carried out in 2006 and 2007 were 63.44% and 57.50%, respectively. The number of anthers in one flower, the number of pollen in one anther and the number of pollen in one flower were found higher in cultivars, whereas these traits turned out to be lower in A. orientalis genotypes. 'Orientalis 6' was notable pollen viability, the number of anthers in one flower, the number of pollen in one anther and the number of pollen in one flower, while the highest pollen germination percentage was recovered from 'Orientalis 9' had in 2006 and from 'Orientalis 5' in 2007. Morphological homogeneity (%) was found to be high in all orientalis types both experimental years. The results obtained with A. orientalis genotypes proved that they could well be employed as pollinizer for hybrid improving work to be made with almond cultivars. (C) 2012 Friends Science PublishersÖğe Determining total phenolic content and total antioxidant capacity of loquat cultivars grown in Hatay(Wolters Kluwer Medknow Publications, 2010) Polat, A. Aytekin; Caliskan, Oguzhan; Serce, Sedat; Saracoglu, Onur; Kaya, Cemal; Ozgen, MustafaSeveral fruit characteristics of five loquat (Eriobotrya japonica (Thunb.) Lindl.) cultivars/selections grown in Dortyol, Hatay, Turkey were investigated in 2008. The cultivars/selections included 'Baduna 5', Guzelyurt 1, 'Hafif Cukurgobek', 'Ottaviani,' and Type 1. The characteristics evaluated included fruit weight, width, length, seed number and weight, flesh/seed ratio, total soluble solids (TSS), pH, acidity, total phenolic (TP) content, and total antioxidant capacity (TAC), determined by the ferric reducing antioxidant power ( FRAP) assay. The analyses were conducted by three replicates, with 30 fruits in each replicate. The results indicated that there were significant differences among the cultivars, for all the traits tested. For example, 'Hafif Cukurgobek' and 'Ottaviani' had smaller fruits than others, although 'Hafif Cukurgobek' had heavier seeds. The flesh/seed ratio was the highest in Type 1, while 'Hafif Cukurgobek' had the highest pH and high soluble solids. 'Baduna 5' and 'Hafif Cukurgobek' had the highest acidity. The TP ranged from 129 ('Baduna 5') to 578 ('Hafif Cukurgobek') mg gallic acid equivalent (GAE)/kg fresh fruit (fw). 'Hafif Cukurgobek' also had the highest FRAP mean (12.1 mmol Trolox Equivalent (TE)/kg fw). The results suggest that loquat cultivars have a variable range of TP content and a relatively high total antioxidant capacity, which is crucial for human health.Öğe Earliness, yield, and fruit quality characteristics in low chill peach-nectarines: a comparison of protected and open area cultivation(Tubitak Scientific & Technological Research Council Turkey, 2021) Caliskan, Oguzhan; Bayazit, Safder; Gunduz, Kazim; Kilic, Derya; Goktas, SultanThis study was carried out to determine the effects of protected cultivation on the earliness, yield, and fruit quality characteristics of some low chill peach-nectarine cultivars grown in the eastern Mediterranean region of Turkey. Phenological observations, yield parameters, and fruit quality characteristics were investigated:The chilling durations as CH (chilling hours), CU (chilling unit), and heat accumulations were determined. The 'Astoria' cultivar reached the highest cumulative yield of 29.11 kg/tree and 38.72 t/ha, and fruit size was 131.89 g and 61.74 mm in protected cultivation. The CH and CU values under protected cultivation were 28% and 40% lower than in open area cultivation, respectively. The heat accumulation was 30% higher for G DIH30 in the protected cultivation. The results of this study revealed that low chill peach-nectarine cultivars grown in protected cultivation showed variable earliness, yield, and fruit quality depending on chilling duration and heat accumulation.Öğe Early detection of graft-incompatibility in hawthorn (Crataegus azarolus L.) trees on apple, pear, and quince rootstocks(Consejo Superior Investigaciones Cientificas-Csic, 2022) Kacal, Emel; Caliskan, Oguzhan; Ozturk, Gokhan; Gur, Ibrahim; Kocal, Hakki; Karamursel, Omer F.; Kilic, DeryaAim of study: This study was conducted to determine the usability of some clonal rootstocks of apple (MM 106 and MM 111), pear (Fox 11), and quince (Quince A) for hawthorn trees propagation. Area of study: Fruit Research Institute, Isparta and Hatay Mustafa Kemal University, Hatay, Turkiye. Material and methods: 'Sultan' hawthorn cultivar was budded on the following clonal rootstocks: pear Fox 11, quince A, and apple MM 106 and MM 111. Plants of hawthorn seedlings (Crataegus azarolus L.) budded with 'Sultan' cv. were used as control. External visual diagnosis of the scion-rootstock graft combinations was performed by observing visual symptoms in budded trees growing in nursery conditions, as well as anatomic and histological investigations of the incompatibility in the laboratory. Main results: In this study, healthy scion development and callus tissue in the graft region were formed in the seedling rootstock as well as on Fox11 and Quince A clonal rootstocks. In contrast, MM 106 and MM 111 apple rootstocks showed incompatibility symptoms, with insufficient scion vigor and unstructured callus tissue development. Research highlights: 'Tanslocated' and 'located' graft incompatibility symptoms were observed in Sultan/MM 106 and Sultan/MM 111 combinations. Further studies are necessary to confirm the early good compatibility found in nursery conditions, testing the effect of those clonal rootstocks from different species (Fox11 and Quince A) on vigor, yield, and fruit quality traits in orchard conditions.Öğe Effect of harvest maturity on volatile compounds profiling and eating quality of hawthorn (Crataegus azarolus L.) fruit(Elsevier, 2021) Dursun, Ahmet; Caliskan, Oguzhan; Guler, Zehra; Bayazit, Safder; Turkmen, Dilek; Gunduz, KazimThe effect of maturity stage on fruit quality characteristics, sensory attributes and volatile composition was investigated in the most important hawthorn cultivar (Sultan). The fruit skin color was used as the maturity index for the classification of hawthorn considering their maturity stages as immature (green), mature (green-yellow) and over mature (yellow). The volatile organic compounds (VOCs) of hawthorn fruit at each maturity stage were analyzed by solid-phase micro-extraction (SPME) and gas chromatography-mass spectrometry (GC-MS). The results indicated that the quality traits of the Sultan cultivar were affected by the maturity stage. From immature to over mature stages, firmness and titratable acidity decreased whereas fruit size (weight, diameter and length), edible fruit ratio, pH and esters (butyl and hexyl hexanoates, hexyl and cis-3-hexenyl acetates) increased in Sultan cultivar. The highest amount of esters along with the occurrence of butyl butanoate was observed in over mature fruit in comparison with immature and mature ones. PCA analysis of volatile organic compounds separated successfully hawthorn fruit according to the maturity stages. The results showed that mature and over mature fruit were more preferred by panelists. Those fruit had the highest level of esters being responsible for strong fruit flavor, along with low pH and low fruit firmness compared to immature ones.Öğe Effects of Organic and Conventional Production Systems on Plant Vigor, Fruit Yield and Fruit Quality Attributes of Bananas Cultivated in the Mediterranean Region of Turkey(Springer, 2023) Bodur, Emre; Kilic, Derya; Caliskan, OguzhanThis study was designed to compare the plant vigor, fruit yield and quality characteristics of bananas produced by organic and conventional production systems in the Mediterranean region of Turkey. The two orchards under protected cultivation were located near each other in order to exclude any possible microclimate effects on the investigated properties. A significant difference was detected in the yield and the fruit quality parameters, based on the management systems and cultivars. 'Dwarf Cavendish' and 'Grande Naine' cultivars grown in conventional production were found to have more hands per bunch (14.00 and 14.20, respectively) than those grown in organic production (8.80 and 10.40, respectively). The largest fruit weight was found in the 'Dwarf Cavendish' (162.35 g) and 'Grande Naine' cultivars (190.81 g) from organic production. 'Dwarf Cavendish' had the highest bunch weight (46.20 kg) and yield (74.8 t/ha) from conventional cultivation, whereas 'Grande Naine' had the highest bunch weight (47.60 kg) and yield (69.9 t/ha) from organic cultivation. For both cultivars, fruits from organic cultivation analyzed at the ripe eating stage (stage 6) had greater total soluble solids, acidity, fruit peel L values, and pulp color b* values than the fruits grown with conventional cultivation. Sensory tests indicated that the organically grown bananas had a better flavor. These results reveal the widespread potential of organic banana cultivation in the Mediterranean region of Turkey.Öğe Fruit characteristics of fig cultivars and genotypes grown in Turkey(Elsevier, 2008) Caliskan, Oguzhan; Polat, A. AytekinIn this study, fruit quality characteristics of some cultivars and types of fig (Ficus carica L.) were determined in Dortyol, Hatay, Turkey, which has a Mediterranean climate. The main fig cultivars grown in Turkey ('Sarilop', 'Bursa Siyahi', 'Goklop', 'Yediveren', 'Yesilguz', 'Morguz', 'Sari Zeybek', and 'Ufak Yesil') were evaluated along with 24 selections from a larger collection from the Mediterranean Region of Turkey. Several pomological characteristics of the genotypes were determined on 5-year-old trees during the 2001 and 2002 growing season. Averaged over the 2 years, fruit weight ranged between 22 and 52 g, total soluble solids content (TSS) ranged between 20.1 and 27.4%, and acidity ranged between 0.09 and 0.26%. 'Bursa Siyahi', 'Goklop', 31-IN-17, 31-IN-11 and 31-IN-09 produced the largest fruits in terms of fruit weight and dimensions. 31-IN-01, 31-IN-02, 'Yesilguz', 'Morguz' and 'Ufak Yesil' had the highest TSS. 'Yediveren', 'Goklop', Bursa Siyahi' and 31-IN-16 scored the highest in overall quality according to the weighted ranked method. Based on the results obtained 'Yediveren, 'Goklop' and 31-IN-16 could be alternatives to 'Bursa Siyahi', currently the most favored fresh table fig cultivar. These alternatives appear to have potential for both local consumption and export markets. Our results also indicate extensive diversity among Turkish figs permitting marketing of a broad range of fresh fig traits. (C) 2007 Elsevier B.V.

Cultivars as Affected by Genotypes and Seasons(Univ Agr Sci & Veterinary Med Cluj-Napoca, 2012) Caliskan, Oguzhan; Bayazit, Safder; Sumbul, AhmetThis study was conducted over two growing seasons (2010 and 2011) to evaluate effects on fruit quality and phytochemical properties of new Turkish cultivars, hybrid between Irano-Caucasian- and European eco-geographic groups, and some important apricot cultivars in the eastern Mediterranean region of Turkey. Fruit quality characteristics, sensory traits, and phytochemical parameters were investigated. The data showed that considerable variation existed in fruit quality and phytochemical properties of Turkish, and foreign apricot cultivars based on genotypes and growing seasons. The new hybrid cultivar 'Cagataybey' contained the highest total soluble solid content (14.6%), rich total phenolic (93.9 mg GAE 100g(-1) fw), and total antioxidant capacity levels (9.8 mmol Fe2+ kg(-1) fw), and >50% of blush color on the fruit peels among the cultivars. The fructose and sucrose values showed positively significant correlations with total phenolics (r = 0.55 and r = 0.69, at p<0.05, respectively). The authors had estimated that the data will be useful for breeding studies to improve fruit quality and nutritional contents of apricot cultivars.Öğe Genetic diversity and population structure in caprifigs (Ficus carica var. caprificus) using SSR markers(Spanish Natl Inst Agricultural & Food Research & Technolo, 2018) Caliskan, Oguzhan; Bayazit, Safder; Ilgin, Muruvvet; Karatas, Nesrin; Ergul, AliAbundant wild and cultivated fig germplasm can be found in Turkey, a center of diversity for figs; however, many of these valuable genetic resources have not yet been identified or characterized using molecular markers. In the present study, microsatellite markers were used to characterize a set of 96 caprifig (Ficus carica var. caprificus) accessions from Turkey. The caprifig accessions showed considerable polymorphism with an average of 8.3 alleles per locus. The number of alleles per locus varied from three for the loci LMFC18 and LMFC23, to 14 for the loci FCUPO38-6 and FCUP008. Genetic distance values and cluster analyses revealed high genetic similarities, except for the reference group, among the caprifig groups. Factorial correspondence analysis also separated the caprifig groups, suggesting that caprifig populations from Turkey were unmixed, probably because of low gene flow; likely because gamplasm has not yet been moved among geographical areas and because many caprifig populations arose from propagation by seed. In our population structure analysis, the caprifig accessions could be grouped according to the regions from where they were sampled. Our molecular data revealed great genetic diversity within this caprifig germplasm. This genetically rich caprifig germplasm resource will be useful for both fig breeding programs and analysis of the complex genetic structure of figs that reproduce using various pollination strategies.Öğe Growth and fruit quality of some foreign loquat cultivars in the subtropical climate of the Turkish Mediterranean region(Amer Pomological Soc, 2006) Polat, A. Aytekin; Caliskan, OguzhanLoquat is an important fruit for the Mediterranean Region of Turkey. Four loquat cultivars ('Kanto', 'Baffico', 'Dr. Trabut' and 'Gold Nugget') were evaluated from 2001 to 2004. Growth, phenology and fruit characteristics were determined in Hatay, on the eastern Mediterranean coast of Turkey. The trunk diameter and annual shoot growth were significantly higher in 'Kanro' than 'Baffico.' and 'Dr. Trabut'. The highest yield was from 'Kanto' and 'Gold Nugget'. Harvest dates ranged from 18 May to 27 May. The earliest maturing cultivars were 'Dr. Trabut' and 'Baffico', while the latest maturing cultivar was 'Kanro'. 'Dr. Trabut' had significantly higher fruit weight than 'Baffico'. Mean seed weight ranged between 3.9 and 6.0 g and average number of seeds per fruit ranged between 2.8-4.5; 'Dr. Trabut' had significantly higher values than 'Kanto' for both of these variables. The flesh/seed ratio in 'Kanto' was significantly higher than 'Gold Nugget'. 'Baffico' had the highest total soluble solids content while 'Gold Nugget' had the lowest. The results suggest that these cultivars can be grown in Mediterranean climate successfully. Adaptation of the cultivars to the region is most likely to increase the production and quality of loquat as well.Öğe Influences of presowing treatments on the germination and emergence of fig seeds (Ficus carica L.)(Univ Estadual Maringa, Pro-Reitoria Pesquisa Pos-Graduacao, 2012) Caliskan, Oguzhan; Mavi, Kazim; Polat, AytekinSeed germination of fig seeds is important for obtain seedlings with high variability in breeding studies, and for producing mosaic virus-free seedlings. This experiment was carried out to evaluated the effects of several treatments (priming with water for 24h, GA(3) at 500 and 1000 ppm for 24h, 3% KNO3 for 24h, and stratification at 4 degrees C for 7, 14 and 21 days) on seed germination and emergence of 'Bursa Siyahi' and 'Sarilop' fig cultivars. The application of GA(3) increased the germination and emergence of these fig seeds. The highest percentages of germination and emergence were obtained with GA(3) at 500 or 1000 ppm for both cultivars. The seed germination and emergence of the cultivar 'Bursa Siyahi' were higher than observed with the 'Sarilop'. The application of GA(3) at 500 ppm or 1000 ppm reduced the time to germination and emergence from the seeds of both cultivars. In summary, the GA, treatments showed efficacy to overcome the dormancy of these fig seeds.Öğe Inheritance of Earliness and Fruit Quality Characteristics in Five Apricot Progenies(Springer, 2022) Altan, Huru; Bircan, Mustafa; Caliskan, OguzhanThis study aimed to determine the genetic heritability of earliness and fruit quality characteristics in five apricot progenies. The study established the contribution of heterosis as well as the genetics of parents involved in crosses to trait heritability. The data are suitable for developing breeding strategies for apricot improvement. The phenological and fruit quality characteristics of the 'Alata Yildizi' x 'Bebeco' (AY x B), 'cagataybey' x 'Ninfa' (cB x N), 'cagataybey' x 'Stark Early Orange' (cB x SEO), 'Sahinbey' x 'Precoce de Tyrinthe' (SB x T), and 'Alata Yildizi' x 'Ninfa' (AY x N) progenies were evaluated. Considerable differences were found among F1 progenies depending on the parents involved. Broad-sense heritability coefficients ranged from 0.27 to 0.99 in the crossbreeding combinations. The AY x B and cB x SEO combinations were promising in terms of early flowering and fruit ripening with negative heterosis. The high correlation and regression coefficients between mid-parents and mean progenies, heritability, and heterosis ratio suggest that the use of appropriate parents in apricot breeding programs is critical.Öğe Loquat production in Turkey(Int Soc Horticultural Science, 2007) Polat, A. Aytekin; Caliskan, OguzhanTurkey is an important world producer of loquat. According to the 2003 statistics, Turkey ranks fourth in world loquat production yielding approximately 12,000 tons (t). Until the last decade, loquat growing was carried out only in isolated home gardens for local consumption. After the economic value of loquat was realized, demand for commercial production rapidly increased. The total production in 1980 (3,000 t) was increased more than four-fold by 2003 and reached about 12,000 t produced from 246,000 trees. In Turkey, Mediterranean region has the most suitable ecological conditions for growing loquat. According to 2003 statistics, 96% of total loquat production of Turkey is from the coastal Mediterranean zone. Within the Mediterranean region, Antalya and Icel provinces are the major producers. In Turkey, loquat is consumed as an early season fresh fruit. The major part of production is consumed within Turkey, but some product is exported mainly to Saudi Arabia, Kuwait, Jordan, Russia, Sweden, Germany and other European countries. Introduction and adaptation studies combined with breeding efforts is underway to obtain high yielding cultivars with large, high quality fruits, resistant to diseases (mainly to scab). Improvement in handling and transportation efforts may help solve some of the present problems in loquat production in Turkey. Research must focus on high-density plantings, protected cultivation and dwarf rootstocks.Öğe Mediterranean Figs (Ficus carica L.) Functional Food Properties(Elsevier Inc., 2015) Caliskan, OguzhanIn recent years, consumers have been increasingly interested in fruits and vegetables due to increasing knowledge about the foods' high content of health-promoting nutrients. In this regard, the fig is one of the most important fruit species in the Mediterranean diet, and it is accepted as a symbol of long life throughout the world. This chapter shows the functional food properties of the Mediterranean fig. Figs are low in sodium and have no fat or cholesterol, and their functional food properties include significant amounts of vitamins, amino acids, sugars, and antioxidant compounds. The richness of a fig's nutrient contents depends on the cultivar that produces it. The black- and purple-fruited cultivars have 2-fold greater total antioxidant capacity, 15-fold greater total anthocyanins, and 2.5-fold greater total phenolics than green- and yellow-fig cultivars. The soluble fiber content of figs has been shown to help control blood sugar, lower blood cholesterol, and supplement the diet, aiding weight loss in obese humans. Interest in figs with rich nutrient contents is expected to increase. © 2015 Elsevier Inc.

In Europe, the fruit, leaves, and flowers of the plant were traditionally employed in the treatment of heart problems because of their antispasmodic, cardiotonic, hypotensive, and antiatherosclerotic effects. Today, the plant is mainly used to treat cardiovascular diseases, and it remains a therapeutic agent for cancer, diabetes, cough, flu, asthma, stomach ache, rheumatic pain, nephritis, and hemorrhoids in Mediterranean traditional medicine. Of the the many hawthorn species, Crataegus monogyna Jacq. is commonly cultivated in Mediterranean countries. © 2015 Elsevier Inc.

However, many characteristics that can be used in identification are considered problematic in terms of time, labor, and sustainability. Therefore, it is necessary to optimize and use the most successful of these characteristics. This chapter aims to reveal the morphological properties that have been found successful in identifying fig genetic resources from past to present. Edible figs (Ficus carica var. domestica) and caprifig (Ficus carica var. caprificus) have different morphological characteristics, a gynodioecious species, making them a gynodioecious species. Therefore, it is necessary to investigate them separately. In edible figs, some plant characteristics such as ripening time and leaf characteristics, fruit characteristics such as size, shape, skin and ostiole cracking, skin and flesh color, and chemical properties such as total soluble solids (TSS), acidity, TSS/acidity, sugar profile, and phytochemical contents such as total antioxidant activity, total phenolics, and total anthocyanins are successful in distinguishing genotypes from each other. For the profichi product used in caprification in caprifigs, fruit characteristics such as fruit size, skin and pulp color, the number of gall flowers, pollen number per fruit, and pollen characteristics such as pollen size and shape, and pore number are successful in distinguishing individuals. The most distinctive parameters will contribute to selecting suitable parents in the establishment of fig breeding programs and the identification of genotypes. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

Browicz) genotypes to be used as rootstock(Springer, 2024) Yildiz, Ercan; Aglar, Erdal; Sumbul, Ahmet; Yaman, Mehmet; Caliskan, Oguzhan; Popescu, Gheorghe Cristian; Popescu, MonicaWith its enormous genetic pool, Turkiye is the homeland of the fig and many plant species. The common fig species in the country's natural population are Ficus carica var. caprificus (male figs), Ficus carica var. domestica (female figs; edible figs), and Ficus carica var. rupestris. In this study, the morphological and molecular characterization of 42 genotypes, including those obtained by selection from the Ficus carica var. rupestris (Hausskn.) Browicz population, which is naturally spread in a limited area in Tunceli province, was performed. This study evaluated the qualitative and quantitative characteristics of 23 fig genotypes. These results showed that tree growth habit, lateral shoot formation, apical dominancy, and leaf length characteristics were highly discriminant variables for phenotypic description in wild fig genotypes. The genetic relationship between the genotypes was demonstrated with 12 SRAP and 9 ISSR primers. As a result of the study, it was determined that the genetic similarity values ranged between 0.52 and 0.94. It was determined that the first five essential components (PCA) contributed 20.87%, 13.21%, 10.66%, 9.58%, and 7.11% of the total variation, respectively, and their cumulative rate corresponded to 61.43% of the total variation. Very detailed results on the genetic variation in the fig population in the region were obtained by morphological features and molecular methods. The seven genotypes selected were propagated to determine their potential for dwarf rootstocks. The results of the present study may provide significant leads for further research on this subject. The potential of dwarf rootstocks in figs can be an essential tool for modern fruit growing.Öğe Morpho-pomological diversity of Turkish pear (Pyrus communis L.) accessions in eastern mediterranean region of Turkey(Wydawnictwo Akad Rolniczej W Lublinie, 2016) Bayazit, Safder; Caliskan, Oguzhan; Sümbül, AhmetConservation and sustainable use of plant genetic resources is important to meet the demand for future food security. This study was conducted on twenty-five native pear accessions sampled from Hatay, province, in eastern Mediterranean region of Tur-key. In these accessions, ripening time, productivity, and some important pomological traits were determined such as fruit weight, fruit sizes, total soluble solids contents, pH, and acidity. The grittiness, flavor, and juiciness were also measured as sensory analysis. These results showed that the earliest ripening among the all studied accessions were ‘Biçin 1' and ‘Biçin 2' (June 25 in 2009 and June 23 in 2010), while the latest accessions were ‘Dağarmudu 1' and ‘Dağarmudu 2' (November 8 in 2009 and November 5 in 2010). In pear accessions, productivity was identified as medium and high. The fruit weight of pear accessions were ranged between 28.29 and 160.02 g, seed numbers were ranged be-tween 0.56 and 10.00, total soluble solid contents were ranged between 10.00 and 18.50%. In pear accessions, 15 instead of all 21 of morpho-pomological fruit properties were able to explain 85.0% of the total variation. As a result, some pear accessions may be recommended for both pear cultivation and the breeding studies in terms of earliness and flavor. © by Wydawnictwo Uniwersytetu Przyrodniczego w Lublinie, Lublin 2016.Öğe Morphological diversity of caprifig (Ficus carica var. caprificus) accessions in the eastern Mediterranean region of Turkey: Potential utility for caprification(Elsevier, 2017) Caliskan, Oguzhan; Bayazit, Safder; Ilgin, Muruvvet; Karatas, NesrinThe present study was carried out to determine the morphological and pollinizer characteristics of six standard cultivars and 90 caprifig accessions grown in eastern Mediterranean region of Turkey. The mamme, profichi and mammon crop sets of caprifigs were evaluated in 28 accessions and six standard cultivars in 2014 and 2015. The accessions Mersin06 and Osmaniye02 were found to be persistent and the remaining accessions were found to be caduceus. The dates on which the pollinator wasp Blastophaga emerged from profichi fruits ranged from 28 May to 07 July according to means of two years in the eastern Mediterranean region of Turkey. Pearson correlation analysis showed that the number of gall flowers, male flowers and the number of viable pollen grains per fruit in caprifigs were strongly dependent on fruit size (dimensions and weight). Principle component analysis indicated that the number of gall flowers per fruit; date of emergence of the Blastophaga wasps from the fruit; duration of Blastophaga emergence, percentages of pollen viability and germination; and pollen number per anther, per flower and per fruit could be useful parameters for assessing whether caprifig accessions would be useful pollinizers. The early season accessions Hatay06, Adana03 and Adana12; the mid-season accessions Hatay22, Hatay35 and Kmaras05; and the late season accessions Hatay20, Hatay13 and Hatay19 scored the highest in overall quality using a weighted, ranked index. Our study demonstrated great morphological and pollinizer variability among the caprifig accessions, which makes them valuable genetic resources to incorporate into breeding programs in addition to their use for caprification.
