  Kalkisim, Ozgun; Aydin, Mehmet Zahit; Ozdes, Duygu; Duran, Celal

  Turkey, located within the Western Asia gene center, is a significant genetic center for many fruit species, including pears. Rize, a province in the Northeastern part of Turkey, is located within the Northeast Anatolia Region, which falls within the genetic center area where pears have undergone evolutionary development. This study aimed to identify promising local Eğrisap pear clone genotypes with superior traits and to introduce them into economic use. For this purpose, Rize province and its districts were surveyed, and fruit and leaf samples were collected from pre-selected Eğrisap pear clone types. These samples were subjected to pomological, morphological, and chemical analysis. The JMP 13 statistical software package was used to compare the Eğrisap pear clone types. According to the research results, the pomological and morphological traits of the clone types varied as follows: fruit weight (99.10–139.54 g), fruit width (54.52–65.41 mm), fruit length (57.58–68.83 mm), fruit stem length (50.75–59.50 mm), fruit stem thickness (2.36–2.91 mm), core width (5.15–7.55 mm), core length (9.73–14.51 mm), flesh firmness (3.61–7.13 lb), seed number (5.30–8.55), leaf width (45.80–60.04 mm), leaf length (64.53–82.37 mm), petiole length (37.04–60.99 mm), petiole thickness (0.83–1.20 mm), and soluble solid content (SSC) (9.10 %-16.0 %). Regarding chemical composition, the pH values of the clone types ranged from (3.78–4.22), titratable acidity (0.22 %-0.47 %), protein content (1.50 %-4.95 %), vitamin C content (0.92–2.28 mg/100 g), ash content (1.16 %-4.30 %), and total sugar content (9.66 %-17.28 %). Mineral element analysis of the local pear varieties revealed that iron content ranged from (0–14.7 µg/g), copper (2.90–9.12 µg/g), manganese (2.9–11.6 µg/g), magnesium (321.7–771.5 mg/g), zinc (0 µg/g), sodium (9.6–39.6 µg/g), potassium (5.43–14.50 µg/g), calcium (50.1–219.7 µg/g), cobalt (0.01–0.31 µg/g), cadmium (0–0.1 µg/g), and nickel (0.08–4.41 µg/g). Among the local Eğrisap pear clones grown in Rize, clone type 53 IYD 01 was identified as having the most superior quality criteria and chemical composition. Consequently, it is recommended that this clone type be introduced to producers for cultivation.

  Kinetics and Isotherm Evaluation for Adsorptive Removal of Anionic and Cationic Dyes from Aqueous Media by Sulfuric Acid-Modified Beech Sawdust

  Ozdes, Duygu; Ozeken, Sengul Tugba; Top, Yener; Kalkisim, Ozgun; Duran, Celal

  A novel and efficient adsorbent was prepared by modifying Fagus orientalis L. (beech) sawdust with H2SO4. The adsorption behavior of H2SO4-modified beech sawdust (SMBS) was investigated by batch experiments to offer a straightforward, inexpensive, and effective method for the retention of anionic and cationic model dyes, indigo carmine (IC) and methylene blue (MB), from wastewater. The experimental conditions were optimized by investigating the effects of the initial pH, initial concentrations of IC and MB dyes, dosage of SMBS, period of the contact, and the presence of salts in the aqueous media on the adsorptive performance of SMBS. The initial pH values of the aqueous solutions, from which IC and MB dyes will be removed, were optimized as 2.0 and 6.5 (natural), respectively. The optimum contact time for the adsorption of both dyes onto SMBS was determined to be 240 min. The mechanisms in the adsorption of IC and MB onto SMBS were investigated by evaluating the experimental data through different isotherm and kinetic models. The Langmuir isotherm model and pseudo-second order kinetic model performed well in explaining the mechanism of adsorption. Langmuir monolayer adsorption capacity of SMBS adsorbent was 38.85 mg g−1 for IC and 58.82 mg g−1 for MB. As a result, CMCP exhibited excellent performance in adsorbing organic pollutants, providing a low-cost and easily prepared alternative to other adsorbents found in the literature.

  Kalkisim, Ozgun; Ozdes, Duygu; Baltaci, Cemalettin; Duran, Celal

  The present study aims to identify the heavy metal contents of white mulberry (Morus alba L.) and black mulberry (Morus nigra L.) that are grown in the city center of Gumushane province and its neighboring counties. Heavy metal analyzes were performed in the fruits, leaves and soils of the plants. The control samples, on the other hand, were collected from the mulberry trees located 3 km away from the highway where the vehicle traffic and industrial activities are at their lowest. Sample collection was performed twice a year, namely during the ripening period and fully ripening period of the fruits. The analyses of the heavy metals were performed by using inductively coupled plasma-mass spectrophotometry (ICP-MS). The obtained results were compared with the acceptable limits of heavy metal for humans as established by the World Health Organization (WHO), Turkish Food Codex (TFC) and the literature and an opinion was submitted as to whether they present any risk in terms of human health. When the available data is evaluated, the mulberries grown in Gumushane province, were found to have presented a health risk in terms of Pb, Cd, Ni, Cu, Zn, Mn and Co metals.

  Kalkışım, Özgün; İslam, Ali; Çelik, Hüseyin

  ÖZETLaz kirazı veya taflan olarak da adlandırılan karayemiş, son yıllarda Türkiye ve bazı Kafkas ülkelerinde popüler olmaya başlayan herdemyeşil bir meyvedir. Bu çalışmada Prunus laurocerasus türüne ait Kiraz karayemiş çeşidinden farklı zamanlarda alınmış olan yeşil, yarı-odunsu ve odunsu yapraklı çeliklerin köklenmesi üzerine farklı dozlardaki IBA uygulamalarının etkisi araştırılmıştır. Ekim, Aralık, Şubat ve Temmuz aylarının ilk yarısında ve farklı odunlaşma aşamalarında alınan çelikler 5 farklı dozda (0, 50, 100, 500 ve 100 ppm) IBA uygulanmıştır. Çelikler sera şartlarında alttan ısıtmalı tavalardaki perlit içerisinde ve mistleme altında köklendirilmiştir. Temmuz ayında alınan yarı odunsu çelikler köklenme, fidan randımanı ve yaşama oranı bakımından %100lük başarı göstermiştir. Köklenme derecesi ise Aralık ayında alınan çeliklerde 7.72 ile en yüksek olmuştur. 100 ppm IBA dozu gerek köklenme (%96.44), gerek fidan randımanı (%90.22) gerekse yaşama oranı bakımından en yüksek değerleri vermiştir. Bu çalışmanın sonuçlarına göre karayemişler, Temmuz ayında alınan yapraklı yarı odunsu çeliklere 100 ppm gibi düşük IBA dozu uygulanarak seradaki perlit ortamında ve mistleme altında kolaylıkla çoğaltılabilir.
