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 EFFECT OF CITRUS ROOTSTOCKS ON LEAF MINERAL COMPOSITION OF 'OKITSU', 'CLAUSELLINA', AND 'SILVERHILL' MANDARIN CULTIVARS(Taylor & Francis Inc, 2012) Toplu, Celil; Uygur, Veli; Kaplankiran, Mustafa; Demirkeser, T. Hakan; Yildiz, ErcanCitrus performance is strongly related with rootstock. This study was conducted to investigate leaf nutrient contents of 'Okitsu', 'Clausellina' and 'Silverhill' mandarin cultivars budded onto sour orange, 'Carrizo' and 'Troyer' citrange rootstocks in Dortyol, Turkey in 2004 and 2005. The maximum nitrogen (N), potassium (K), and copper (Cu) contents were determined for 'Clausellina'; phosphorus (P) for 'Okitsu'; and sodium (Na) for 'Silverhill'. Calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), and zinc (Zn) uptake were similar for the mandarin cultivars. 'Carrizo' citrange at N, K, Mg, Mn, and Cu uptake; 'Troyer' citrange at N, P, K, and Fe uptake; and common sour orange at Ca, Zn, and Na uptake was superior on the other rootstocks. It was observed that 'Carrizo' and 'Troyer' citrange rootstocks had advantages over sour orange in nutrient uptake. Thus, growth performance, yield, and quality parameters considered, 'Carrizo' and/or 'Troyer' citranges could be suggested as rootstocks for the studied mandarin cultivars under similar ecological conditions.Öğe Effect of natural lipid on pollen germination and pollen tube growth on loquat(Asian Network for Scientific Information, 2007) Demirkeser, T. Hakan; Çalişkan, O?uzhan; Polat, A. Aytekin; Özgen, Mustafa; Serçe, SedatThe present study evaluated the effects of a natural lipid, Lysophosphatidylethanolamine, (L) on the eight-year old loquat (Sayda) orchard located on coastal Mediterranean region in Hatay. The applications were conducted prior to bloom (Treatment I) and the same branches were treated again after two weeks from Treatment I (Treatment I+II) while the control branches were treated with water. After two weeks from the second application, buds were sampled from all experimental units and pollen viability test were conducted by standard methods. Randomly sampled buds from all treatments were kept on a room temperature to obtain pollen for both varieties and treatments. The pollen were germinated on media having various concentration of sucrose (5, 10, 15 and 20%) and incubated at 10, 15 and 20°C. The Petri dishes were placed on -20°C after 3, 6, or 9 h incubation to consecutively determine their germination rates and pollen tube growths under a light microscope. The results clearly demonstrated that L application before bloom significantly improves pollen germination rate and pollen tube growth although it has no effect on pollen viability. Among the incubation treatments, 20°C gave the most favorable results for both pollen germination rate and pollen tube growth. The highest pollen germination rates were recovered from 20% sucrose concentration while the longest pollen tubes were at 15%. The positive effects of L may be very advantageous for loquat growing especially for the early fruit production regions. © 2007 Asian Network for Scientific Information.Öğe The effects of citrus rootstocks on Valencia Late and Rhode Red Valencia oranges for some plant nutrient elements(Academic Journals, 2008) Toplu, Celil; Kaplankiran, Mustafa; Demirkeser, T. Hakan; Yildiz, ErcanIn citrus production, the rootstocks utilization is beneficial for solving the problems caused by soil, climates, pests and diseases as well as achieving higher productivity and quality, earlier and later fruit productions. Therefore, citrus producer almost exclusively utilizes rootstocks. The major rootstock of Turkish citrus production is sour orange while trifoliate, Troyer and Carrizo citranges are utilized as well. In this study, we determined the rootstock effects on some plant nutrient element status of Rhode Red Valencia and Valencia Late oranges budded on sour orange, Troyer and Carrizo citranges in 2004 and 2005. Our results were similar in both experimental years with few expectations. The nutrient status of the two orange cultivars tested significantly differed from K and Ca concentrations in both years. However, all cultivars mean were within the range of optimal limits except Zn. The rootstock had significantly different means for all elements tested in both years. We demonstrated that the citrus rootstocks had different abilities to utilize plant nutrient elements. For N, K, Mg, Mn and Cu, Carrizo citrange has the highest means while Troyer and sour orange have the highest concentrations for P and Fe, and Ca, Zn and Na, respectively. We recommend utilizations of Carrizo and Troyer citrange rootstocks for eastern Mediterranean region citrus production as they had higher ability to utilize many plant nutrient elements playing important roles in productivity and quality.Öğe LEAF MINERAL COMPOSITION OF 'NOVA', 'ROBINSON' AND 'FREMONT' MANDARIN CULTIVARS ON DIFFERENT ROOTSTOCKS(Taylor & Francis Inc, 2010) Toplu, Celil; Uygur, Veli; Kaplankiran, Mustafa; Demirkeser, T. Hakan; Yildiz, ErcanRootstock selection has a critical importance for mineral nutrition of budded cultivars. This study was conducted at the experimental farm of Mustafa Kemal University, Dorlyol, Turkey. The aim of this study was to investigate the effect of sour orange, Troyer and Carrizo citrange rootstocks on the leaf nutrient contents of 'Nova', 'Robinson', and 'Fremont' mandarin cultivars in the 2004 and 2005 growing seasons. Carrizo citrange was examined for nitrogen (N), potassium (K), magnesium (Mg), sodium (Na), and manganese (Mn); Troyer citrange for iron (Fe); and sour orange for calcium (Ca) and zinc (Zn) were superior on the others. Nitrogen, phosphorus (P) and Mg levels of mandarin leaf budded on sour orange were under or just above the deficiency threshold. Potassium, Mn, and Zn content of 'Robinson'; P, Ca and Fe content of 'Fremont'; and Cu content of 'Nova' were statistically higher. Therefore, it can be concluded that Carrizo rootstock may be suggested for the region and regions with similar ecological conditions.Öğe Performance of ''Rio Red'' Grapefruit on Seven Rootstocks in the Eastern Mediterranean Region of Turkey(Tarbiat Modares Univ, 2014) Yildiz, E.; Kaplankiran, M.; Demirkeser, T. Hakan; Toplu, C.; Uysal-Kamiloglu, M.The effects of rootstocks such as 'sour orange' (Citrus aurantium L. var. 'Yerli'), 'Carrizo' and 'Troyer citranges' (Citrus sinensis Osb. x Poncirus trifoliata Raf), 'Smooth Flat Seville sour orange' (Citrus spp. hybrid of uncertain origin), 'Brazilian sour orange' (Citrus aurantiam L. var. 'Brasilian'), 'Volkameriana' (Citrus volkameriana Tan. and Pasq.) and 'Calamondin' (possibly Citrus reticulate var. austerexFortunella hybrid, Swingle) on plant growth, fruit yield, and quality of 'Rio Red' grapefruit were investigated from 2008 to 2012. Rootstocks were found to have significant effects on plant growth, fruit yield, and quality. 'Rio Red' grapefruit trees budded on 'Carrizo' and 'Troyer citranges' showed higher vegetative growth parameters (canopy height, diameter, and volume) than the trees on the other rootstocks. The trees on 'Volkameriana' and 'Carrizo citrange' produced higher percentage of cumulative yield of about 55.1 and 34.3%, respectively, than the trees on 'sour orange'. 'Rio Red' grapefruit budded on 'Carrizo citrange' had higher fruit quality such as thin rind, high juice content, and more color development than the other rootstocks. 'Carrizo citrange' was the most promising rootstock for 'Rio Red' grapefruit in Dortyol, Eastern Mediterranean region of Turkey.Öğe The Performance of Persimmon (Diospyros kaki Thunb.) Cultivars Under Mediterranean Coastal Conditions in Hatay, Turkey(Amer Pomological Soc, 2009) Toplu, Celil; Kaplankiran, Mustafa; Demirkeser, T. Hakan; Ozdemir, A. Erhan; Candir, Elif Ertuek; Yildiz, ErcanThe cultivation of persimmon has been increasing rapidly in the Mediterranean region recently. We investigated the performance, phenological and pomological characteristics of ten persimmon (Diospyros kaki Thunb.) cultivars ('Amankaki', 'Eylul', 'Fuyu', 'Hachiya', 'Hana Fuyu', 'Harbiye', 'Jiro', 'Kaki Tipo', 'O'Gosho', and 'Vainiglia') during 2001 to 2007 in the Mediterranean climate in Dortyol, Hatay, Turkey. 'Jiro', 'Fuyu', 'O'Gosho', 'Hachiya' and 'Eylul' had small canopy volume. Fruit maturity occurred in the first week of October for 'Amankaki', 'Eylul' and 'Hachiya', which all matured earlier than other cultivars. The highest cumulative yields were obtained from 'Vainiglia' and 'Amankaki'. The mean fruit weight varied from 251 g for 'Hana Fuyu' to 87 g for 'Eylul'. 'Eylul' and 'Hachiya' had red skin, while that of 'Vainiglia', 'Kaki Tipo' and 'Harbiye' was yellow. The results demonstrate that regional ecological conditions are appropriate for the cultivation of persimmon. The yield of 'Vainiglia', 'Jiro', 'Amankaki' and 'Fuyu' was high and regular; 'Eylul' and 'Hachiya' had the most colorful fruit. We recommend 'Vainiglia', 'Jiro', 'Amankaki' and 'Fuyu' for commercial growing in the region.
