Walnut has an important part in the human diet since ancient times. In this study, seven walnut genotypes (28 CO 012, 28 SK 033, 28 SK 050, 28 SK 108, 28 SK 351, 28 SK 550, 28 SK 935) and the 'Sebin' cultivar grown in Turkey were selected and evaluated for proximate composition and mineral quantities. Concerning their composition the main constituent of kernels was oil ranging from 62.17 to 68.93%, the nutritional value being around 700 kcal per 100 g of kernels. Kernels had a range of 12.15 to 16.85% in protein content and 10.54 to 19.53% in carbohydrate content. Ash ranged from 1.68 to 2.05% while the moisture content of the kernels was found between 3.29-6.62%. Potassium was the major mineral compound in all genotypes sampled, ranging from 372.69 to 554.69 mg/100 g, followed by calcium, ranging from 112.02 to 237.08 mg/100 g and magnesium ranging from 127.08 to 155.37 mg/100 g.

(Inst Soc Horticultural, 2013) Yerlikaya, Cemile; Coman, M; Chitu, E; Yıldız, Hüseyin; Ertürk, Ümran; Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü.; 35605229000; 7801661220
This study was carried out to determinate the effect of CaCl2 sprays on some physiological and chemical quality parameters (as Fruit Flesh Firmness, Soluble Solid Content, ions) and physiology disorders (as Water Core, Superficial Scald) on 'Granny Smith' apple fruits harvested in 180, 190, 200 and 210 days after full bloom and stored 3 and 6 months under 0 +/- 0.5 degrees C temperature and 90-95% relative humidity conditions. Ca applications had no clear effect on water core but they enhanced flesh firmness and SSC of fruits. Harvest date is very effective on superficial scald incidence. Ca applications affected Ca and K contents of fruit, but did not change Mg content. K/Ca and K+Mg/Ca ratios decreased with increase in Ca applications.

(Asian Journal of Chemistry, 2007-05) Yerlikaya, Cemile; Ertürk, Ümran; Sivritepe, Nuray; Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü.; 0000-0003-3023-7028; AAG-7343-2021; DSI-7459-2022; 7801661220; 6507111971
In vitro propagated three-node shoots of blackberry cv. Chester Thornless were subjected to different concentrations of CuSO4.5H(2)O (control, 50, 100 and 150 ppm) and ZnSO4.7H(2)O (control, 50, 100, 200 ppm) in (1)/(4) strength MS medium, supplemented with 0.5 mg L-1 BAP, 30 g L-1 sucrose and 7 g L-1 agar, for 4 weeks. Excess levels of Cu on the growing media reduced dry biomass production of explants. In contrast to Cu treatments, dry biomass production was enhanced increasing Zn level up to 50 ppm in the growth medium. Moreover, relative growth rates of explants were not modified by 100 and 200 ppm Zn treatments. The relative chlorophyll content of leaves tended to decrease in blackberry with increasing supply of Cu and Zn. Thus, the predominant symptom appeared in metal treated explants was chlorosis. Significant changes were observed in mineral composition of the explants, however, concentrations were generally above mineral deficiency levels. The above-ground biomass of the explants exposed to different levels of Cu accumulated 499.5-1726.1 mg kg(-1) in dry matter Cu and the levels were about 54-186 times higher than those of the control. Similarly, Zn content in above-ground biomass of explants treated with 50, 100 and 200 ppm Zn increased almost 10, 14 and 18 times compared with those of the non-treated ones. Based on these preliminary results, the possible usefulness of blackberry for phytoremediation technologies is discussed.

The proximate composition of eleven walnut (Juglans regia L.) genotypes (28 SK 010, 28 SK 055, 28 SK 041, 28 SK 601, 28 SK 925, 28 SK 028, 28 SK 118, 28 SK 350, 28 SK 930, 28 SK 850, 28 SK 036) and three walnut cultivars (Sebin, Bilecik, Kaman 1) produced in Turkey were determined. The oil content of the samples ranged from 61.32 to 69.35%, corresponding to an energy value of approximately 710 kcal per 100 g of kernel. The protein content ranged from 10.58 to 18.19%, and the carbohydrate composition was between 9.05 and 18.92%. The ash content ranged from 1.53 to 1.99%, and the moisture content of the kernels was between 1.91 and 4.48% the oleic acid content of the oils ranged from 17.90 to 33.35% of the total fatty acids. The linoleic acid content ranged from 43.15 to 60.20%. The linolenic acid content ranged from 9.98 to 13.00%. The palmitic acid content was between 5.21 and 8.40%. Stearic acid ranged from 2.36 to 4.25%. Potassium was the major mineral in all the samples, ranging from 359.73 to 482.97 mg/100 g. Calcium was the next most abundant mineral, ranging from 109.45 to 335.97 mg/100 g, followed by magnesium, ranging from 126.01 to 165.15 mg/100 g.
Response of the cherry rootstock to water stress induced in vitro
(Acad Sciences Czech Republic, 2008-09) Yerlikaya, Cemile; Türkan, Ismail; Bor, Melike; Özdemir, Fethi Ahmet; Sivritepe, Nuray; Ertürk, Ümit; Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü.; 7801661220; 6507111971
The in vitro response of sweet cherry (Prunus cerasus x P. canescens) rootstock Gisela 5 to increasing water deficit in the culture medium was studied. Water stress induced by the incorporation of 1, 2 and 4 % polyethylene glycol (PEG-8000) into the Murashige and Skoog medium was applied for 6 weeks. PEG-induced water stress reduced shoot dry mass, length, water content and relative chlorophyll content. Water stress also induced leaf necrosis without causing loss of viability in the explants. The increase in malondialdehyde content indicated oxidative stress. The activities of antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), peroxidase (POX) and glutathione reductase (GR) were also significantly elevated. The concentrations of K, Ca, Fe and Mn of shoots were decreased.
Responses of the cherry rootstock to salinity in vitro
(Academy Sciences Czech Republic, 2007-09) Yerlikaya, Cemile; Bor, Melike; Özdemir, Fethi Ahmet; Türkan, İsmail; Ertürk, Ümit; Sivritepe, Nuray; Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü.; 7801661220; 6507111971
The in vitro response of sweet cherry rootstock Gisela 5 (Prunus cerasus x Prunus canescens) to increasing concentrations of NaCl (0, 50, 100 and 150 mM) in the Murashige and Skoog culture medium was studied. Induced salinity reduced growth and chlorophyll content in shoots but had no effect on water content. The increase in malondialdehyde content indicated that salinity induced oxidative stress which was accompanied with the visible symptoms of salt injury in the shoots. Antioxidant enzymes, such as superoxide dismutase, ascorbate peroxidase, peroxidase, catalase, and glutathione reductase were also significantly elevated. Although no change was observed in the Cl concentration, Na concentration of shoots significantly rose and NaCl treatments impaired K, Ca and Mg nutrition and induced imbalance in K:Na and Na:Ca ratios.
