Publication Studies on the gall characteristics of dryocosmus kuriphilus in chestnut genotypes in Yalova and Bursa provinces of Turkey(Univ Agr Sci & Veterinary Med Cluj-napoca, 2019-01-01) Gençer, Nimet Sema; Mert, Cevriye; GENÇER, NİMET SEMA; MERT, CEVRİYE; Ziraat Fakültesi; Bitki Koruma Bölümü; AAH-3908-2021; EWK-9746-2022The Asian chestnut gall wasp Dryocosmus kuriphilus is a global pest of chestnut (Castanea spp.). It has been spreading in Turkey's forests and orchards since 2014. This pest imposes a big threat to the Turkish chestnut industry, which is among the top producers in the world. Its gall morphology has been related to pest pressure and host cultivar, thus eventually modulating plant damage with heavy impact on growth and fruit production. We compared gall characters (position on plant organ, ratios, dimensions, volumes, number of larval chambers) in wild Castanea sativa, two local cultivars and a Euro Japanese hybrid. Overall, leaf galls were more common (55.36%), followed by the stem (19.6%) and leaf stipule galls (15.29%). The mean number of chamber and volume value of gall types were 1.52-5.93 and 0.43-2.15 cm(3), respectively. The highest values were observed in 'stem gall'. The more gall formation was observed in the wild chestnut trees and 'Marigoule' than the other local varieties.Publication The performance of some walnut (juglans regia) cultivars in the conditions of Bursa, Turkey(Galenos Publ House, 2023-01-01) Utku, Özlem; Ahi Koşar, Dilan; AHI KOŞAR, DİLAN; KOŞAR, MEVLÜT BATUHAN; MERT, CEVRİYE; Ertürk, Ümran; ERTÜRK, ÜMRAN; Orhangazi Yeniköy Asil Çelik Meslek Yüksekokulu; JCE-7775-2023; AAG-7343-2021The present study aimed to evaluate the pomological and phenological traits, as well as yield potential and incidence of external defects of some local ('Bilecik', 'Mara 12', 'Mara 18', 'Sebin', 'Sen 1') and foreign ('Chandler', 'Fernette', 'Fernor', 'Howard', 'Pedro', 'Serr') walnut cultivars grown in Bursa (north-west in Turkey) conditions between 2014 and 2020. The first leafing was observed in Mara 12, Serr, Sebin, and Mara 18 cultivars, while Fernette and Fernor were the last leafing cultivars. The female blooming period of the cultivars was recorded to be the longest in Mara 18 (15 days) and Sebin (16 days) and that was the shortest in Bilecik and Serr (10 days). The male blooming period was recorded as the longest in Chandler, Fernette, Bilecik, and Sebin (16-18 days) and that was the shortest in Mara 12 and Serr (10 days). The average yield per tree of cultivars ranged between 1.87 kg (Sebin) and 14.21 kg (Pedro). Walnut blight was observed on average in 15.85%, sunburn in 10.21%, codling moth in 5.11%, anthracnose in 3.23%, and bird damage in 2.35% of the fruits. The healthy nut percentage ranged from 40.06% (Sen 1) to 76.50% (Chandler). The nut weight of cultivars was between 9.91 g (Mara 12) and 16.27 g (Sen 1). Kernel percentage varied from 36.31% (Sen 1) to 53.56% (Mara 12). The principal component analysis conducted to distinguish the cultivars suggests that the most important factors could be reduced to five components. The results showed that Mara 12, Chandler, Fernor, and Howard were suitable cultivars for commercial cultivation in Bursa conditions.Publication The king fruit versus lateral fruit thinning effects on yield and fruit quality in apple(Taylor & Francis Inc, 2007-01-01) Mert, Cevriye; Ertürk, Ümran; Soylu, Arif; Öztürk, Özgür; MERT, CEVRİYE; ERTÜRK, ÜMRAN; Soylu, Arif; Öztürk, Özgür; Ziraat Fakültesi; Bahçe Bitkileri Bölümü; AAH-3908-2021; AAG-7343-2021; HIA-5036-2022; JXW-4193-2024This research was conducted to determine the king versus lateral fruit thinning effects on yield and fruit quality of 'Elstar', 'Granny Smith', 'Starkrimson Delicious', 'Ultra Red', 'Topred', and 'Jonagold' apple (Malus domestica Borkh.) cultivars grafted on MM106 rootstock in 2002-2003. Removal of the king fruit (KFR) treatment partially increased the yield in 'Jonagold', 'Elstar', and 'Granny Smith' cultivars while the effects were different by years in 'Starkrimson Delicious'. Leaving of the king fruit (KFL) treatment gave better results in the 'Topred' cultivar, and similar effects were obtained from both treatments in 'Ultra Red' cultivar. Non-significant differences were obtained from both treatments with respect to fruit weight in the 'Topred', 'Starkrimson Delicious', 'Jonagold' and 'Granny Smith' cultivars. Leaving of the king fruit treatment increased the fruit weight significantly in 'Elstar' and 'Ultra Red' cultivars in 2002. The values of fruit flesh firmness (lb), total soluble solids content (%), pH, titratable acidity (%), total and invert sugar quantity (g/100 g(-1)) were not found to be significantly different between the treatments with a few exceptions. The 'KFR' treatment that removed the dominant effect of the king fruit can be recommended for the 'Elstar' and 'Jonagold' cultivars because this treatment increased the yield and did not decreased the fruit weight significantly in these cultivars except for 'Elstar' in 2002. On the other hand 'KFL' treatment can be recommended for the 'Granny Smith', 'Topred' and 'Ultra Red' cultivars. Although this treatment decreased the yield of 'Granny Smith' it increased the mean fruit weight 45.6-62.7 g in the two experiment years. 'Starkrimson Delicious' did not show clear response to the treatments. (C) 2007 by The Haworth Press.

Of these applications, 750 ppm Carbaryl for 'Starkspur Golden Delicious', 1250 ppm Carbaryl for 'Granny Smith' and Starkrimson Delicious', and 5 ppm NAA for 'Jonagold' increased the mean number of flower buds significantly, compared with the control treatments. The other treatments of Carbaryl, NAA, and NAA + Carbaryl also increased the mean number of flower buds in a nonsignificant sense with a few exception. A negative correlation between the final fruit set and the mean number of next year's flower buds was found for three cultivars. The correlation coefficients were r = -00.5150 (P < 0.05), r = -0.6999 (P < 0.05), r = -0.0335 for 'Starkspur Golden Delicious', 'Granny Smith', and 'Jonagold' cultivars, respectively. However, this relationship was positive and nonsignificant for ` Starkrimson Delicious' (r = 0.1980). (C) 2005 by The Haworth Press, Inc.

Egemen; SAKIN, AHMET EGEMEN; Mert, Cevriye; MERT, CEVRİYE; Taşdemir, Yücel; TAŞDEMİR, YÜCEL; Ziraat Fakültesi; Çevre Mühendisliği Bölümü; 0000-0002-0513-0520Because of their possible carcinogenic effects, it is crucial to determine levels of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) in olive oils. However, there are a few studies about these pollutants' levels in olive oils and no other studies reported PAHs, PCBs and OCPs at the same time and during the ripening period of olives in olive oils. A modified clean-up technique was successfully applied for eliminating lipidic components. Additionally, this study does not just report the concentrations of these pollutants but also inspects the sources depending on the actual sampling site. Also, PCBs and OCPs carcinogenic risks in olive oil were reported for the first time in the literature. This study aims to present levels, carcinogenic risks, sources and concentration changes during the ripening period of these pollutants in olive oil. For this purpose, fruit samples for oil extraction were collected between the beginning of the fruit ripening and harvest period. Obtained olive oils from the fruits were extracted and cleaned up using the QuEChERS method. GC-MS and GC-ECD were used for the quantitative analysis of the targeted pollutants. The average concentrations for Sigma(16)pAHs, Sigma(37)PCBs and Sigma(10)OCPs were 222.48 +/- 133.76 mu g/kg, 58.26 +/- 21.64 mu g/kg and 25.48 +19.55 mu g/kg, respectively. During the harvest period, the concentrations were in a decreasing trend. Calculated carcinogenic risks were above acceptable limits for all groups and traffic, wood-coal burning, atmospheric transport and previous uses were the main sources. Results of the source determination indicated that some possible sources could be prevented with regulations and precautions.
