Öğe Determination of Heat Requirements and Effective Heat Summations of Some Pomegranate Cultivars Grown in Southern Anatolia(SPRINGER, 2014) Ikinci, Ali; Mamay, Mehmet; Unlu, Levent; Bolat, Ibrahim; Ercisli, SezaiTemperature (high and low) is one of the most limiting environmental factors for growth and production of fruits in different parts of the world. For temperate-zone fruit species, a certain total heat requirements are needed in order to obtain ripe fruits. The aim of this study was to determine heat requirements of three commercial pomegranate cultivars ('Suruc', 'Katirbasi' and 'Hicaznar') grown in Southern Anatolia region. The cultivars showed a narrower range of heat requirements for flowering (growing degree hours, GDH), i.e. 'Suruc' (25,000), 'Katirbasi' (25,270), 'Hicaznar' (28,000) and a wide range of heat requirements for fruit ripening, i.e. 'Suruc' (73,670), 'Katirbasi' (74,105) and 'Hicaznar' (88,052) GDH. Under the Sanliurfa province conditions, two years average of effective heat summation requirement from bud swelling to 50 % flowering stage for 'Suruc', 'Katirbasi' and 'Hicaznar' cultivars are calculated as 643, 655 and 718 growing degree days (GDD) and from bud swelling to harvest are 2734, 2802 and 3289 GDD. It can be concluded that the effective heat summation of Sanliurfa province is enough for commercial growing for all pomegranate cultivars.Öğe Morphological Characterization of Cherry Rootstock Candidates Selected from Central and East Black Sea Regions in Turkey(HINDAWI PUBLISHING CORPORATION, 2013) Koc, Aysen; Celik, Zumrut; Akbulut, Mustafa; Bilgener, Sukriye; Ercisli, Sezai; Gunes, Mehmet; Gercekcioglu, ResulThe use of rootstocks particularly for sweet cherry cultivars is of great importance for successful and sustainable production. Choosing the right cherry rootstocks is just as important as choosing the right cultivar. In this study, 110 sweet cherry, 30 sour cherry, and 41 mahaleb types displaying rootstock potential for sweet cherry cultivars were selected from Central and East Black Sea Regions in Turkey. The morphologic characteristics of the studied genotypes were compared with the standard clonal rootstocks PHL-A, MaxMa 14, Montmorency, Weiroot 158, Gisela 5, Gisela 6, and SL64. A total of 42morphological UPOV characteristics were evaluated in the selected genotypes and clonal rootstocks. The obtained data were analyzed by using principal component analysis and it revealed that eigenvalues of the first 3 components were able to represent 36.43% of total variance. The most significant positive correlations of the plant vigor were determined with leaf blade length and petiole thickness. According to the diversity analysis of coefficients, the 05 C 002 and 08 C 039 genotypes were identified as being similar (6.66), while the 05 C 002 and 55 S 012 genotypes were determined as the most distant genotypes (325.84) in terms of morphology.Öğe Morphological diversity among pomegranate genetic resources from Northeastern part of Turkey(WFL PUBL, 2013) Orhan, Emine; Ercisli, Sezai; Esitken, AhmetThis research was conducted in the Coruh Valley located in Northeastern part of Turkey. The valley is accepted one of the 34 hotspots in terms of plant biodiversity in the world. Pomegranate cultivation in this region is one of the main agricultural activities with viticulture. In spite of importance and richness of pomegranate biodiversity from this region, local germplasm of this region has not been investigated yet. For this reason pomegranate (Punica granatum L.) population of c. 10,000 seedling shrubs was examined with regard to morphological fruit properties. In the first year of the study, 56 promising pomegranate genotypes were selected from the valley. There was huge morphological variation among genotypes, in terms of particular fruit color, fruit weight, fruit dimensions, aril color and fruit firmness. The genotypes exhibited a range of 147-769 g for fruit weight, 65.19-107.08 mm for fruit width, 56.84-96.93 mm for fruit length, 2.69-6.05 mm peel thickness and 14.8-49.8 kg/cm(2) fruit firmness. The selected promising genotypes were preserved in a collection parcel as perspective parental genotypes for future breeding activities.Öğe Response of Yield, Growth and Iron Deficiency Chlorosis of 'Santa Maria' Pear Trees on Four Rootstocks(UNIV AGR SCI & VETERINARY MED CLUJ-NAPOCA, 2016) Ikinci, Ali; Bolat, Ibrahim; Ercisli, Sezai; Esitken, AhmetThis study was conducted on the 'Santa Maria' pear (Pyrus communis L.) budded on various rootstocks: pear seedling (Pyrus communis L.) and three quince (Cydonia oblonga Mill.) rootstocks, respectively 'BA 29', 'QA' and 'QC', under calcareous soil and semi-arid conditions, during 2004-2012. The results showed that the highest cumulative yield per ha (53.1 t ha(-1)), fruit weight (304.1 g), fruit volume (337.2 cm(3)), fruit flesh firmness (22.3 lb.) and titratable acidity (0.21%) was obtained from trees on 'BA 29' rootstock. The highest soluble solids content (15.8%), cumulative yield per tree (78.08 kg tree(-1)), trunk cross sectional area (79.03 cm(2)) and the lowest titratable acidity (0.18 %) were obtained from pear seedling. The most vigorous trees were grown on pear seedling, followed by 'BA 29', 'CIA' and 'QC' rootstocks. The 'Santa Maria' pear variety's leaf chlorophyll content on all rootstocks fell during the study period up to 60 DAFB compared with 30 DAFB. It was found that leaf chlorophyll and Fe contents were higher in trees on pear seedling and 'BA 29' rootstocks and lower in those on 'QA'.
