Öğe The Current and Future Situations for Sweet Cherry Production in the Eastern Mediterranean Region, Hatay, Turkey(Int Soc Horticultural Science, 2008) Polat, A. A.; Durgac, C.; Serce, S.In most countries, large-scale sweet cherry (Prunus avium L.) production usually occurs in small climatically suitable regions. There are large areas in Turkey that are suitable for sweet cherry production, such as Hatay, which is located in the eastern part of the Mediterranean region with production centered in Belen and Iskenderun. According to 2004 data, 530 t of sweet cherries were produced in Hatay. Of this, 59% was from Belen and 36% from Iskenderun. Studies to determine production potential and possible problems in the Hatay region revealed that the origins of the sweet cherries grown in the region are unknown, and an important cultivar mixture was observed as well. Moreover, significant problems were determined for orchard establishment, cultivar selection, irrigation, fertilization, pruning, cultivation techniques, harvesting and postharvest applications. Future studies to find solutions to these problems should increase sweet cherry production and may, therefore, increase both domestic consumption and export potential.Öğe Detection of Hop Stunt Viroid in Pomegranate (Punica granatum L.) Trees in the East Mediterranean Region of Turkey(Int Soc Horticultural Science, 2009) Gazel, M.; Caglayan, K.; Serce, C. Ulubas; Durgac, C.Hop stunt viroid (HSVd) infects several fruit tree species with agronomic importance, including pomegranate. Different pomegranate cultivars growing in Hatay, Adana and Icel provinces were surveyed for the presence of HSVd. The main symptoms observed were yellowing and some alteration of the leaves. This kind of symptoms showing samples and also symptomless leaf samples were collected in June-August 2006. In total 152 different pomegranate leaf samples were analyzed for the presence of HSVd. Total RNAs were isolated from pomegranate leaves and used as template in RT-PCR. HSVd was not detected in all tested pomegranate samples.Öğe Determination of Fruit Quality Parameters of Sweet Cherries Grown in High Elevation Regions in Hatay, Turkey(International Society Horticultural Science, 2008) Polat, A. A.; Durgac, C.; Kamiloglu, OeThe Belen region of Hatay, Turkey, which has a high elevation (700 to 1000 m) has suitable ecological conditions for sweet cherry (Prunus avium L.) production, the main income for Benlidere's growers. However, the origins of the sweet cherries grown in the region are unknown and there is a mixture of important cultivars. This study was conducted to determine the quality parameters of the sweet cherries grown in the region. The study was carried out in the Benlidere village of Belen. Two sweet cherry orchards, differing 140 m in altitude, were selected and the fruit from the genotypes grown in these orchards were compared. From 1995 to 1998, the fruit harvested from these orchards were sampled and pomological analyses, such as average fruit weight, fruit dimension, pedicel length, seed weight, total soluble solids (TSS) and acidity, were measured. Harvest date varied between the 15(th) of May and 22(th) June. Averaged over four years, the fruit weights of the genotypes varied from 2.6 g to 6.4 g, and the TSS ranged from 13.1% to 18.0%. It was concluded that sweet cherry production in the region could be improved with new cultivars and modern production techniques.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 Effects of deficit irrigation treatments on yield and plant growth of young apricot trees(Taylor & Francis Ltd, 2015) Bozkurt, S.; Odemis, B.; Durgac, C.An experiment was conducted to investigate the effects of deficit irrigation on yield and tree growth of young apricot trees (Prunus armeniaca L. cv. Ninfa) during three growing seasons with three irrigation intervals (7, 14 and 21 days) and five irrigation levels based on reduction coefficients (K-cp) of class A pan evaporation (0.0, 0.25, 0.50, 0.75 and 1.00). Growth and yield variables such as trunk diameter, mean branch length, volume of tree, total number of fruit, mean fruit weight, total fruit yields of trees, evapotranspiration and water use efficiencies were determined. While the irrigation interval treatments had significant effects on trunk diameters and branch lengths of the trees, the irrigation level treatments significantly affected all the tree growth variables. Variation in irrigation level also affected yield, with yield and fruit size increasing as irrigation increased up to at least 0.75 of pan evaporation. The treatment with 25% water deficit and a 14-day irrigation interval is suggested as the most suitable irrigation strategy for young apricot trees under a Mediterranean climate.
