Öğe AKDENİZ BÖLGESİ’NDE ÖRTÜALTI MEYVE YETİŞTİRİCİLİĞİ(2021) Bayazit, Safder; Çalışkan, Oğuzhan; Kılıç, DeryaÖrtüaltında meyve üretimi sağladığı erkencilik nedeniyle karlı bir yetiştirme tekniği olarak kabul edilmektedir. Bu nedenle gerçekleştirilen bu çalışmada, Türkiye’nin örtüaltı meyve yetiştirme merkezi olan Akdeniz Bölgesi’ndeki mevcut durum ve yapılan araştırmalar konusunda değerlendirmeler yapılmıştır. Halihazırda, Akdeniz Bölgesi Avrupa’nın en erkenci meyve üretim alanlarına sahip olması, örtüaltı yetiştiricilik ile özellikle Nisan ayı içerisinde sezon dışı meyve üretimine imkan vermesi ile çok önemli bir konuma sahiptir. Nitekim, son on yılda örtüaltı meyve yetiştiriciliğinde %85 oranında bir artış olduğu görülmektedir. Türkiye örtüaltı meyve yetiştiriciliğinin %88.4’ü Akdeniz Bölgesinde gerçekleştirilmektedir. Bu bölgede, örtüaltında muz ve çilek başta olmak üzere üzüm, kayısı, erik, şeftali-nektarin türleri yetiştirilmekte ve en fazla üretim Mersin (414.098 ton) ve Antalya (152.535 ton) illerinde gerçekleştirilmektedir. Sonuç olarak, Akdeniz Bölgesi’nin örtü altı meyve yetiştiriciliğine ilişkin sahip olduğu potansiyel göz önüne alındığında bölgedeki örtüaltı meyve yetiştiriciliğinin geliştirilmesi için daha detaylı araştırmalara gereksinim duyulmaktadır.Öğe Assessment of growth behaviour, yield, and quality parameters of some olive (Olea europaea) cultivars in Turkey(Taylor & Francis Ltd, 2009) Toplu, Celil; Yildiz, Ercan; Bayazit, Safder; Demirkeser, T. HakanOlive (Olea europaea) is one of the oldest cultivated species in the Mediterranean basin and it is widespread throughout the Mediterranean region. In this study, we determined several phenological, morphological, and pomlogical characteristics of a number of olive cultivars when grown in Hatay province in the eastern Mediterranean region of Turkey. The 21 cultivars examined had their origins in Italy, Spain, Tunisia, and Turkey. The earliest flowering was observed in 'Gemlik' and 'Silifke yaglik' on 4 May whereas the latest flowering was in 'Memeli', 'Domat', and 'Savrani' on 10 May. 'Gemlik' and 'Manzanilla de Sevilla' produced the highest Cumulative yield over a 4-year period. The largest fruit were from 'Ascolana', averaging 6.72 g whereas 'Kilis yaglik' (2.05 g), 'Nizip yaglik' (2.33 g), and 'Meski' (2.43 g) had the smallest fruit. The flesh comprised the highest fraction of total fruit weight in Manzanilla de Sevilla.' (86.4%), 'Gemlik' (86.4%), 'Edincik su' (86.3%), 'Hojiblanca' (86.1%), and 'Halhali' (86.0%). The highest oil content was in 'Kilis yaglik' (31.2%) and 'Savrani' (29.3%). Based on our results, 'Gemlik' and 'Manzanilla de Sevilla' are suggested for table olive production in the Hatay region whereas 'Memecik', 'Kilis yaglik', and 'Sari ulak' are the most suitable for oil production.Öğe Chilling requirements of cherries grown under subtropical conditions of Adana(2012) Kuden, Ayzin B.; Imrak, Burhanettin; Bayazit, Safder; Çömlekçio?lu, Songül; Küden, AliThe chilling requirements of different cherry cultivars and the chilling durations of two different cherry growing areas (Pozanti at 1100 m and Adana at 50 m elevations) were investigated. Results depicted that Lapins and Larian gave the lowest (400-450 hours and 94 chill units) chilling requirement. They were followed by Nafrina with 500-550 hours and 120 chill units. Kordia found to be the highest chilling requiring cherry cultivar (700-750 hours and 150 chill units). While, the others were moderate in chilling response. Calculating total growing degree hours, the highest chilling requiring cherry cultivar Kordia needed the least GDH values (14.000 GDH), the others were around 14.00-16.000 GDH. Calculating the hours below 45oF, Pozanti (1100 m elevation) gave 3 or 4 times higher chilling accumulation comparing subtropical conditions of Adana (50 m elevation). However, the chill unit values of Adana and Pozanti were quite similar to each other according to the Richardson's chill units (except 2001-2002-winter period). In comparison of cherry cultivars for dormancy breaking initiation of the buds, Kordia, Larian, Nafrina and Sunburst showed an apical dominancy effect and this effect was the strongest in Sunburst whereas the lightest in Summit. Top cut cuttings of these four cherry cultivars broke dormancy earlier in lateral buds than apical buds. Bud breaks rates of apical and lateral buds in Lapins, Summit and 0900 Ziraat were quite similar to each other. © IDOSI Publications, 2012.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 Fruit Quality and Fatty Acid Composition of Turkish Walnut (Juglans regia) Cultivars and Genotypes Grown in Subtropical Climate of Eastern Mediterranean Region(Friends Science Publ, 2012) Bayazit, Safder; Sumbul, AhmetTurkey has considerable walnut populations in its several different ecological regions. Five cultivars ('Sebin', 'Sen 1', 'Tokat 1', 'Kaplan 86' & 'KR 2') and three genotypes ('Malatya 1', '77H1' & '65/4') selected form different regions were investigated for their fruit quality characteristics and fatty acid compositions in the eastern Mediterranean region of Turkey. The results indicated that the fruit weight ranged from 9.21 g ('Tokat 1') to 22.2 g ('Kaplan 86'), kernel weight ranged from 5.39 g ('Sebin') to 9.79 g ('Malatya 1') and kernel percentage ranged from 36.69 ('Kaplan 86') to 62.84% ('Tokat 1'). Fatty acid profile was a significant parameter distinguishing the walnut cultivars and genotypes. Palmitic acid values of these genotypes were ranged from 6.98 to 8.77%, oleic acid ranged from 19.33 to 36.76%, linoleic acid ranged from 41.55 to 59.89%, linolenic acid ranged from 8.44 to 11.0%, steraic acid ranged from 3.22 to 4.99. Oleic acid content of genotype kernels with dark color (C & h values are low) were the lowest but the linolenic acid contents of them were the highest. 65/4', 'KR 2' and 'Sebin' genotypes were found to be very promising for fruit quality traits and fatty acid profiles in the eastern Mediterranean region of Turkey. (C) 2012 Friends Science PublishersÖğe 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 DETERMINATION OF RELATIONSHIPS AMONG KERNEL PERCENTAGE AND YIELD CHARACTERISTICS IN SOME TURKISH WALNUT GENOTYPES BY CORRELATION AND PATH ANALYSIS(Pakistan Agricultural Scientists Forum, 2012) Bayazit, SafderExperiments were conducted to determine correlations among important fruit and plant characteristics using 12 walnut genotypes (Bilecik, Malatya 1, Sebin, Tokat 1, Kaplan 86, Yalova 1, Yalova 3, Yalova 4, Sen 1, 65/4, 77H1, KR 2). Twelve traits viz., fruit weight, fruit diameter, fruit length, fruit height, shell thickness, kernel weight, shell weight, kernel percentage, shoot length, trunk diameter, tree canopy volume, total number of fruits per tree, and yield per tree were evaluated for correlation and path analysis. Results depicted that kernel percentage and yield were influenced by direct and indirect effects of different characters. Fruit weight and shell weight of walnut were the most important properties that directly reduced the kernel percentage whereas kernel percentage increased as the kernel weight increased. Kernel percentage increased as shell thickness decreased. Total fruit number per tree, fruit height, and kernel percentage were determined as the most important characters that directly affected the yield per tree. Kernel percentage and yield per tree were the most important characters for walnut breeding researches and were positively associated. Fruit and shell weight had negative effect on both the kernel percentage and the yield per tree whereas fruit weight and tree canopy volume had the positive effect on both of kernel percentage and yield per tree. It is suggested that these properties can be used as a criterion for selection in walnut breeding research studies.Öğe Determination of relationships among kernel percentage and yield characteristics in some turkish walnut genotypes by correlation and path analysis(2012) Bayazit, SafderExperiments were conducted to determine correlations among important fruit and plant characteristics using 12 walnut genotypes (Bilecik, Malatya 1, Şebin, Tokat 1, Kaplan 86, Yalova 1, Yalova 3, Yalova 4, Şen 1, 65/4, 77H1, KR 2).

In this study, some vegetative and fruit quality attributes of eight blackberry genotypes ('Jumbo', 'Chester Thornless', 'Black Satin', 'Navaho', 'Bursa 1', 'Bursa 2', 'Bursa 3', 'Bartin') were evaluated in 2002 and 2003. The greatest cane numbers and cane lengths were recorded for 'Bursa 2'. They were followed by 'Bursa 3' and 'Chester Thornless' in both years. Harvest periods ranged from 8 to 44 days and occurred from the middle of June until the end of August. 'Jumbo' and 'Bursa 1' were the earliest ripening cultivars. 'Bursa 2' had the longest harvest period. The highest yields were obtained from 'Bursa 1,' 'Bursa 2' and 'Chester Thornless.' 'Jumbo' had the largest fruits. The highest TSS/TA ratio was found in 'Navaho'. (C) 2005 by The Haworth Press, Inc.

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 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 FRUIT CHARACTERISTICS AND FATTY ACID CONTENTS OF AMYGDALUS ORIENTALIS (MILL) AND AMYGDALUS TURCOMANICA (LINCZ) ALMOND SPECIES(Parlar Scientific Publications (P S P), 2018) Bayazit, SafderWild almond species are important genetic resources resisting to the adverse effects of drought stress and being a major dwarf rootstocks pool for Prunus species. So far, nine wild almond species have been identified in Turkey. In order to determine the fruit characteristics, fat content and fatty acids composition, 12 A. orientalis and 8 A. turcomanica types were used in this research. The results of measurement of nuts and kernels varied according to species and genotypes, and this difference was statistically significant. Average nut weight (0.75 g), nut length (18.49 mm), kernel weight (0.27 g) and kernel length (15.10 mm) were higher in A. orientalis species. Average nut width and height, thickness of shells, yield, and kernel width and height values were also close to each other between two species. All of these values were lower than the Prunus dulcis (Mill.) cultivars. As in the fruit characteristics the average fat content of the two species were very close (50.59%, 50.61%), the content of palmitic (8.24%), palmitoleic (0.36%) and linoleic acid (25.70%) were high in A. turcomanica while the content of stearic (2.21 %) and oleic acid (67.53%) were higher in genotypes belonging to A. orientalis species. Palmitic, stearic and linoleic fatty acid contents were found to be higher than cultured cultivars, while the fat percentage obtained from wild almond genotypes was lower than that obtained from cultured cultivars.Öğe Fruit Quality and Phytochemical Attributes of Some Apricot (Prunus armeniaca L.) 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 Hatay yöresi cevizlerinin (Juglans regia L.) seleksiyon yoluyla ıslahı üzerinde araştırmalar(Hatay Mustafa Kemal Üniversitesi, 2000) Bayazit, Safder; Ayanoğlu, HamitÖZET Hatay Merkez ilçe, Altınözü, Samandağ ve Yayladağı ilçe ve köylerinde 1998 yılında yürütülen bu seleksiyon çalışması sırasında toplam 71 ağaçtan meyve örneği alınmıştır.

Ten decamer primers were selected from 50 primers. These primers yielded a total of 155 bands and 126 of them were recorded as polymorphic. Pairwise genetic distances of the samples were used to construct dendograms using Unweighted Pair-Group Method of Arithmetic Average (UPGMA). The study suggests that the morphological differences among cultivars of persimmon might be the result of genetic differences rather than the ecological or growing conditions. The study forms a basic contribution to the characterization of D. kaki population in Turkey.Öğe Morpho-chemical characteristics useful in the identification of Fig (Ficus carica L.) germplasm(Springer International Publishing, 2023) Caliskan, Oguzhan; Bayazit, Safder; Kilic, DeryaMorphological and chemical properties are widely used to identify fig genetic resources. 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.
