Öğe Determination of pomological characteristics of some pomegranate cultivars in Dörtyol (Turkey) conditions(International Society for Horticultural Science, 2012) Polat, A.A.; Caliskan, O.; Kamiloglu, O.In this study, fruit quality characteristics of some pomegranate cultivars ('Hicaz', 'Katirbaşi', 'Çekirdeksiz' and 'Kara Mehmet') were determined in Dörtyol, Hatay, Turkey. Several pomological characteristics of the cultivars were determined from the 2002 until the 2006 growing season. Averaged over the 4 years, pomegranate cultivars had a range of 241.1-319.8 g for fruit weight, 67.5-78.7 mm fruit height, 75.2-85.3 mm fruit width, 2.9-4.0 mm peel thickness and 57.7-64.1% in percent arils. In addition, the total soluble solid content was between 14.3 and 16.6%, pH between 2.97 and 3.20, acidity between 0.39 and 1.59%. Pomegranate cultivars had a green or yellow background color, red or pink peel coverage and aril color, and soft, semi-hard and hard seeds. According to the data obtained, 'Hicaz' and 'Katirbaşi' were found to be promising for cultivation under the ecological conditions in Dörtyol.Öğe Determining performances of some loquat (Eriobotrya japonica) cultivars under Mediterranean coastal conditions in Hatay, Turkey(Rsnz Publishing, 2006) Durgac, C.; Polat, A.; Kamiloglu, O.The growth performances, phenological and pomological characteristics of four loquat (Eriobotrya japonica) cultivars, 'Kanro', 'Baffico', 'Dr. Trabut', and 'Gold Nugget', were studied between 1996 and 2000 in the Mediterranean climate in Kirikhan, Hatay, Turkey. Among the loquat cultivars tested, the biggest trunk diameter and annual shoot growths were measured in 'Kanto' whereas 'Baffico' was found to be the earliest, and 'Kanro' to be the latest ripening cultivar. The largest fruit size was obtained from 'Dr. Trabut', whereas the smallest fruit size from 'Baffico'. 'Dr. Trabut' had the highest seed number and seed weight, and the lowest value of the flesh/seed ratio was calculated in this cultivar. The ratio of flesh to seed was highest in 'Kanro'. The highest total soluble solids (TSS) content was observed in 'Baffico' (11.77%), whereas the lowest TSS was recorded in 'Kanto' (9.09%). The results suggest that these cultivars can be successfully grown in a Mediterranean climate. Adaptation of the cultivars to the region is also most likely to increase the production and quality of loquat.Öğe IMPACT OF ROOTSTOCKS ON FRUIT QUALITY, MINERAL NUTRITION AND LEAF PHYSIOLOGY OF 'RED GLOBE' IN THE EAST MEDITERRANEAN REGION(Aloki Applied Ecological Research And Forensic Inst Ltd, 2022) Kamiloglu, O.Red Globe is a table grape variety with commercial importance, preferred in terms of cultivation. This variety is new to our country and the Mediterranean Region. The objective of the present study was to determine phenological periods, fruit quality, cluster properties, berry characteristics, chlorophyll content, photosynthetic rate and nutrient status of 'Red Globe' on 41 B, SO 4, and 1103 P rootstocks. This grape variety ripened during both years in the first week of August. It was determined that effective heat summation (EHS), required from bud burst until ripeness, was 1600-1700 degree days (d.d). SO4 rootstock yielded the highest value in terms of cluster and berry weights, Total Soluble solids (TSS)/acidity, and pH, and it was followed by 1103 P rootstock. The effect of rootstock on chlorophyll content was found to be similar. Likewise, it was identified that the effect of rootstocks on photosynthetic and transpiration rates was not significant. Effects of rootstocks on leaf mineral matter intake were found to be significant in terms of certain elements. P, K, Ca and Mg macro nutrient element contents were found to be higher in 1103 P rootstock than the other two rootstocks. Rootstocks showed similarity in terms of the intake of micronutrient elements (other than Fe).Öğe INFLUENCE OF SOME CULTURAL PRACTICES ON YIELD, FRUIT QUALITY AND INDIVIDUAL ANTHOCYANINS OF TABLE GRAPE CV. 'HOROZ KARASI'(Pakistan Agricultural Scientists Forum, 2011) Kamiloglu, O.This study was conducted to determine the effects of different cultural practices on vine yield, bunch and berry characteristics, juice quality, total anthocyanins and individual anthocyanins for 'Horoz Karasi' table grape which have been demanded in the recent years. In addition to the control vines, seven cultural practices were compared: cluster thinning, boron, topping, cluster thinning + boron, cluster thinning + topping, boron + topping, cluster thinning + boron + topping. The highest and the lowest yields were obtained from boron+topping (14.94 kg vine(-1)) and cluster thinning (8.58 kg vine(-1)) practices respectively. For cluster weight and number of berries/cluster; cluster thinning+boron+topping practice yielded the highest value, while cluster thinning practice yielded the lowest value. Total soluble solid (TSS), pH, TSS/acidity characteristics were the highest in cluster thinning practice. It was also determined that such practice increased amounts of total anthocyanin and individual anthocyanins significantly more than other practices. Proportional malvidin-3-glucoside percentage was significantly higher than other individual anthocyanins in this variety. Grape quality and composition were affected by the amount of products in vine. Negative correlations were identified between vine yield and TSS, pH, TSS/acidity, total anthocyanins, Cy-3-G, Dp-3-G, Mv-3-G, Pn-3-G, Pt-3-G.Öğe Performance of some peach and nectarine cultivars under east Mediterranean (Hatay/Turkey) conditions(International Society for Horticultural Science, 2012) Polat, A.A.; Caliskan, O.; Kamiloglu, O.Production of peach and nectarine (Prunus persica) in the East Mediterranean region (Turkey) has increased during recent years, requiring information on the performance of modern cultivars in the region. Thus, a long-term project was conducted to investigate bloom date, harvest date, fruit quality, and yield of various peaches and nectarines under the conditions of the East Mediterranean region during 2002 to 2006. 'Early Red', 'Redhaven', 'Dixired', 'Washington', 'J.H. Hale' peach cultivars and 'Cherokee', 'Independence', 'Nectared 4', 'Nectared 6', 'Nectared 8' nectarine cultivars were used in this study. The analysis of average response over four years indicated that 'Early Red' both bloomed (21 March) and was harvested earlier (6 June) than the other peach cultivars, while 'Cherokee' and 'Independence' were harvested earlier (15 June) than the other nectarine cultivars. Averaged over four years, fruit weight was determined at between 84.5 and 130.1 g; flesh/seed ratio between 8.0 and 15.2; total soluble solids (TSS) between 10.0 and 13.1%; pH between 3.27 and 3.52; titratable acidity between 0.58 and 0.83% for peaches and fruit weight was determined between 36.7 and 83.1 g; flesh/seed ratio between 5.8 and 7.7; TSS between 11.4 and 13.4%; pH between 2.95 and 3.49; titratable acidity between 0.86 and 1.40% for nectarines. Yield values ranged from 8.8 kg/tree ('J.H. Hale') to 20.8 kg/tree ('Dixired') for peaches, and 7.4 kg/tree ('Nectared 4') and 14.3 kg/tree ('Cherokee') for nectarines. Overall, 'Redhaven', 'Early Red' and 'Dixired' peaches, plus 'Cherokee' and 'Independence' nectarines showed satisfactory to good performance in this long-term evaluation.Öğe Physiological and biochemical responses to drought stress in some autochthonous grapevines of Turkey(Int Soc Horticultural Science, 2019) Koc, M.; Kamiloglu, O.; Cangi, R.; Yildiz, K.Because of global climate change, the effects of drought stress, which is one of the important abiotic stress factors, are increasing. Therefore, breeding of grapevine cultivars is an important tissue to develop resistance to drought stress. In the present study, we investigated leaf relative water content (RWC), rate of water loss (RWL), membrane stability index (MSI), leaf pigment concentrations [chlorophyll (Chl) a, Chl b, carotenoids], lipid peroxidation (MDA), proline accumulation, and the activities of antioxidant enzymes [catalase (CAT) and ascorbate peroxidase (APx)] in some autochthonous grapevine cultivars ('Karabarcik', 'Manda Gozu', 'Bilecik Irikarasi', 'Horoz Karasi', 'Rumi', 'Tekirdag Seedless', 'Cavus', 'Trakya Ilkeren') in Turkey. Briefly, own-rooted autochthonous grapevines were subjected to drought stress for 7 days and then irrigated at field capacity for 2 days. Plant leaf samples were taken four times (0, 3, 7 and 9. days). Consequently, 'Horoz Karasi' and 'Tekirdag Seedless' exhibited relatively higher tolerance to drought, while 'Kabarcik' showed lower tolerance in response to severe stress. On the other hand, 'Horoz Karasi' and 'Kabarcik' exhibited better performance in the recovery phase.Öğe Relationships among Crataegus accessions sampled from Hatay, Turkey, as assessed by fruit characteristics and RAPD(Springer, 2011) Serce, S.; Simsek, O.; Toplu, C.; Kamiloglu, O.; Caliskan, O.; Gunduz, K.; Ozgen, M.The genus Crataegus known as hawthorns, is the largest genus among the Maloideae, which comprises 265 species. Turkey is one of the genetic centers of Crataegus and there are more than 20 species found in Turkey. The fruits of Crataegus are used as food and have high flavonoid, vitamin C, glycoside, anthocyanidin, saponin, tannin, and antioxidant levels. In this study, we attempted to characterize 15 Crataegus accessions sampled from Hatay, located in Eastern Mediterranean region of Turkey. The accessions belonged to several species; C. aronia (L.) DC. var. aronia, C. aronia var. dentata Browicz, C. aronia var. minuta Browicz, C. monogyna Jacq. subsp. azarella (Griseb.) Franco, and C. orientalis Pall. ex M. Bieb. var. orientalis. Fruit characteristics of the accessions exhibited considerable variation. The multivariate, principle component and cluster analyses indicated that the accessions belonged to three groups: (1) C. aronia var. arona accessions; (2) C. aronia var. dentata accessions; and, (3) C. monogyna subsp. azarella and C. orientalis var. orientalis accessions. The principle component analysis results also revealed that the first three components explained 46, 21, and 14% of the variation, comprising a total of 81%. The fruit length and width, leaf area, and soluble solids contents were highly correlated characteristics for the first three components. The 19 RAPD primers generated a total of 107 bands, where 76 of these were polymorphic. The molecular data analyses by principle coordinate and clustering showed similar results to those of pomological characteristics. There were three groups, (1) C. aronia var. arona accessions; (2) C. aronia var. dentata accession; and, (3) C. monogyna subsp. azarella. C. orientalis var. orientalis accession grouped with C. aronia var. arona accessions. Therefore, it can be concluded that, overall, the diversity patterns of pomological and molecular data, generated by RAPD, for Crataegus are in good agreement and the accessions of C. aronia var. aronia, C. aronia var. minuta, C. monogyna subsp. azarella and C. orientalis var. orientalis accessions.Öğe Research on determination of callus formation capacity in different grape rootstocks and cultivars(International Society for Horticultural Science, 1997) Tangolar, S.; Ergenoglu, F.; Gok, S.; Kamiloglu, O.Callus formation was observed in the cuttings of 8 cultivars and 19 rootstocks following cutting, dipping in paraffin and placing into a water tank. The shortest time from planting to the beginning and maximum callus formation and the highest callus formation rate were observed (80 % in the 19th day, 100 % in the 24th day, respectively) in Harmony rootstock. The lowest maximum callus formation rate (36.7 %) was obtained in the 33 rd day in 8 B rootstock. The highest callus formation (4.0) was observed in King's Ruby cultivar and Harmony rootstock and the lowest callus formation (1.1) was observed in 8 B rootstock.Öğe Rooting characteristics of several grape cultivars and rootstocks(International Society for Horticultural Science, 1997) Tangolar, S.; Gok, S.; Ergenoglu, F.; Kamiloglu, O.Shoot development and rooting characteristics of cuttings of 8 grape cultivars and 22 rootstocks rooted over bottom heated are reported. Rooting rate of cuttings was between 80 % and 100 % in all cultivars and rootstocks except 41 B and 420 A. Lowest response was obtained with 41 B, 8 B, 420 A, 140 Ruggeri, 110 R and 99 R rootstocks. Shoot development was best in Harmony, 5 BB, Rupestris du Lot and 1616 C rootstocks.
