(int Soc Horticultural Science, 2015) Gundogdu, M.; Kazankaya, A.; Muradoglu, F.; Tufenkci, S.; Encu, T.; Sensoy, R. I. Gazioglu
Pomegranate is among the important fruit species for human health and diet for centuries. It is stated in the recent studies that pomegranate is widely used for medicinal purposes, which promotes its preference. In the present study, some pomological and biochemical properties of the eighteen local pomegranate genotypes widely grown in Mardin Province of Turkey were determined. It was determined that the 'DAHL-1' local cultivar had the highest fruit weight (327.45 g) and fruit juice volume (138 ml). The seed weight, soluble solid content, and pH contents of the investigated cultivars ranged from 45.7 to 167.4 g, 10.75 to 16.75 degrees Brix, and 3.11 to 3.98, respectively. Moreover, some other criteria such as fruit juice acidity, fruit size, calyx dimension, seed hardiness, and seed size, shape index, fruit taste were also determined. In the results of analysis, the genotype 'DAHL-1' had more advantageous than the others based on the fruit attractiveness, fruit size, fruit juice volume and other criteria.

Effects of Humic Acid, Whey and Arbuscular Mycorrhizal Fungi (Amf) Applications on Seedling Growth and Fusarium Wilt in Zucchini (Cucurbita Pepo L.)
(Pakistan Agricultural Scientists Forum, 2013) Sensoy, S.; Ocak, E.; Demir, S.; Tufenkci, S.
The effects of Arbuscular Mycorrhizal Fungi (AMF, Gigaspora margarita), whey (50 ml kg(-1)), and Humic acid (HA, 500 mg kg(-1)) applications on seedling growth and Fusarium wilt (FON, Fusarium oxysporum sp. niveum) in hybrid zucchini (Cucurbita pepo L.) cultivar Focus F-1 were investigated. The study was consisted of total 16 treatments including different combinations of FON, AMF, humic acid and whey. There were significant effects of the treatments on seedling growth and some nutrient contents. The treatment which had the highest suppression on Fusarium wilt was the single AMF treatment followed by triple application of AMF, HA, and whey.
Effects of Phosphorus and Nitrogen Applications and Rhizobium Inoculation on the Yield and Nutrient Uptake of Sainfoin (Onobrychis Viciifolia L.) Under Irrigated Conditions in Turkey
(Taylor & Francis Ltd, 2006) Tufenkci, S.; Erman, M.; Sonmez, F.
This study was carried out to determine the effects of phosphorus and nitrogen applications and Rhizobium inoculation on the yield and nutrient uptake in sainfoin grown in Van, Turkey, in 2002 and 2003. Nitrogen application significantly increased plant height, and fresh forage and hay yields, in both years. The highest values were obtained from the 40 kg ha(-1) N. Applications over 40 kg ha(-1) N decreased these parameters. Nitrogen at 40 kg ha(-1) also resulted in the highest nitrogen, phosphor-us, and potassium contents of the plants. The application of 39 kg P ha(-1) significantly increased plant height, and fresh forage and hay yields. Phosphorus also increased nitrogen, phosphorus, and potassium contents. Rhizobium inoculation significantly increased all the parameters investigated over the control. The highest yield and nutrient contents were obtained from the application 40 kg ha(-1) N + 39 kg P ha(-1) + Rhizobium inoculation.
Ion Accumulation in Different Organs of Green Bean Genotypes Grown Under Salt Stress
(Czech Academy Agricultural Sciences, 2006) Yasar, F.; Uzal, O.; Tufenkci, S.; Yildiz, K.
Salt-tolerant Gevas Sink 57 (GS57) genotypes and salt-sensitive 4F-89 French variety, previously determined in our preliminary study, were used in the study. The genotype and the variety exposed to 100mM NaCl application developed different mechanisms to be protected against toxic effects of Na+ ion. Salt-sensitive 4F-89 French variety let Na+ accumulate in all organs. On the contrary, salt-tolerant GS57 did not avoid salt and acted selectively among ions; the majority of toxic ion Na+ accumulated in old leaves and shoots and the plants did not transport them into young leaves. K+ accumulation was high in organs in which Na+ concentrations were low, and vice versa; Na+ content was low in young and high in old leaves of GS57, but K+ content was opposite. Ca2+ content in young leaves of GS57 and 4F-89 decreased; still its content was the highest of all examined ions found in young leaves. This indicated that beans can develop different mechanisms to accept and adapt high levels of salt. Storing toxic ion (Na+) in old leaves and having a limited transmission of salt into young leaves serves as a protection from detrimental effects of salt.
Response of Four Zucchini (Cucurbita Pepo L.) Hybrids To Different Arbuscular Mycorrhizal Fungi
(Pakistan Agricultural Scientists Forum, 2011) Sensoy, S.; Demir, S.; Tufenkci, S.; Erdinc, C.; Demirer, E.; Unsal, H.; Ekincialp, A.
Four zucchini hybrids (Focus F-1, Comet F-1, Natali F-1, and Ezra F-1) inoculated by three different arbuscular mycorrhizal fungi (AMF) [Glomus intraradices (Gi), Glomus etinucatum (Ge), and Gigaspora margarita (Gm)] in a growth chamber experiment were evaluated for seedling traits, nutrient uptake, colonization, and relative mycorrhizal dependency (RMD). Relative mycorrhizal dependency ranged widely among four zucchini hybrids. Gm inoculations had higher positive RMDs, while Gi inoculations had lower negative RMDs. Gm-inoculated Focus F-1 had the highest RMD (30.22%). Arbuscular mycorrhizal fungi inoculated seedlings had wider cotyledons and stems. There were also significant effects of AMF inoculation on the most of nutrients.
