(Univ Agr Sci & veterinary Med Cluj-napoca, 2016) Alp, Sevket; Ercisli, Sezai; Jurikova, Tunde; Cakir, Ozlem; Gozlekci, Sadiye
A rose hip is the fruit of a rose plant and mostly belongs to Rosa canina and Rosa dumalis. These species are genuine found as wild in natural conditions, while in some countries are cultivated for their hips that are picked and used in a wide variety of preparations. Because they contain a variety of antioxidants, carotenoids, flavonoids, polyphenols, leucoanthocyanins and catechins, rose hips are considered to be a good cancer preventative. The Rosa genus has been the focus of many recent studies due to its potential benefit effects on treatment and prevention of several diseases. However, there are few in vitro studies concerning its composition and antioxidant capacity. The aim of the present study was to determine bioactive content, including ascorbic acid, total phenolics, total flavonoids, total carotenoids and antioxidant activity of Rosa dumalis genotypes growing wild in Erzurum province located eastern Anatolia. The results revealed that fruits of Rosa dumalis different genotypes were rich rich in terms of vitamin C, which ranged from 402 to 511 mg/100 g fresh weight base. The total phenolic content varied from 297 to 403 mg/100 g fresh weight. The genotype `E-09' had the highest total flavonoids content(229 mg quercetin equivalent/100 g fresh weight) and the lowest value was attributed to genotype `E-04' with 143 mg/ quercetin equivalent/100 g fresh weight. The antioxidant activity of the genotypes was between 12.9-28.6 mu g Trolox/ml samples. The results revealed that there was enough diversity among Rosa dumalis genotypes for bioactive content and promising genotypes, with high bioactive content, were determined, which can become study material for future breeding activities.

(Soc Biolgia Chile, 2015) Muradoglu, Ferhad; Gundogdu, Muttalip; Ercisli, Sezai; Encu, Tarik; Balta, Fikri; Jaafar, Hawa Z. E.; Zia-Ul-Haq, Muhammad
Background: Cadmium (Cd) is well known as one of the most toxic metals affecting the environment and can severely restrict plant growth and development. In this study, Cd toxicities were studied in strawberry cv. Camarosa using pot experiment. Chlorophyll and malondialdehyde (MDA) contents, catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX) activities and mineral nutrient concentrations were investigated in both roots and leaves of strawberry plant after exposure Cd. Results: Cd content in both roots and leaves was increased with the application of increasing concentrations of Cd. We found higher Cd concentration in roots rather than in leaves. Chlorophyll a and b was decreased in leaves but MDA significantly increased under increased Cd concentration treatments in both roots and leaves. SOD and CAT activities was also increased with the increase Cd concentrations. K, Mn and Mg concentrations were found higher in leaves than roots under Cd stress. In general, increased Cd treatments increased K, Mg, Fe, Ca, Cu and Zn concentration in both roots and leaves. Excessive Cd treatments reduced chlorophyll contents, increased antioxidant enzyme activities and changes in plant nutrition concentrations in both roots and leaves. Conclusion: The results presented in this work suggested that Cd treatments have negative effect on chlorophyll content and nearly decreased 30% of plant growth in strawberry. Strawberry roots accumulated higher Cd than leaves. We found that MDA and antioxidant enzyme (CAT, SOD and APX) contents may have considered a good indicator in determining Cd tolerance in strawberry plant.

(Mdpi, 2022) Bahar, Askin; Cavusoglu, Seyda; Yilmaz, Nurettin; Tekin, Onur; Ercisli, Sezai
Maintaining the postharvest quality of tomatoes, which are essential in the world vegetable trade, is very important; otherwise, storage may cause severe quality and economic losses. This study aimed to determine the effects of 1-MCP treatments on quality and storage time to prevent quality loss and deterioration in tomatoes due to high temperature and to predict ethylene production through the Multivariate Adaptive Regression Splines algorithm during long-term storage. For this purpose, same-sized fruits were divided into three different groups. Two groups were treated with 1-MCP (625 and 1250 ppb), and the untreated fruit was the control. Then, the tomatoes were stored for 39 days at a temperature of 20 degrees C and relative humidity of 85-90%. The results obtained from the present study showed that the 1-MCP treatments prolonged the life and maintained the quality of tomato fruit during storage. The ethylene production and respiration rate were significantly lower in 1-MCP-treated fruit than in the untreated fruit during the storage period (p < 0.05). According to the Multivariate Adaptive Regression Splines algorithm, it was observed that increasing doses of 1-MCP inhibited ethylene production. Furthermore, weight loss and respiratory rate were effective on ethylene production at 100 and 43.9%, respectively. In conclusion, treating the fruit with 1250 ppb of 1-MCP was determined to be the best practice for maintaining all quality criteria during storage.

(Sciendo, 2023) Yilmaz, Nurettin; Islek, Firat; Cavusoglu, Seyda; Necas, Tomas; Ondrasek, Ivo; Ercisli, Sezai
Due to the short shelf life of fresh apricots, special postharvest preservation techniques and practices are necessary to avoid significant economic losses. The purpose of the current study is to bring to light an approach that can be used to extend the storage life of apricot fruits treated with essential oils (EOs) (peppermint, thyme and carob EO) and examine the effects of two altitudes (1000 m and 1200 m) on the organic acid levels and respiration rate of apricot fruit during long-term storage. The results show that growing apricots at high altitudes increases the level of organic acids in the fruit, improving its quality and extending its postharvest life. Additionally, treating apricots with EOs postharvest slows down the respiration rate, reducing the consumption of organic acids during storage compared to the untreated fruit. The organic acid content was significantly higher in 'Kabaasi' than in 'Hacihaliloglu', and fruit harvested at 1200 m had significantly higher levels of organic acid than the fruit harvested at 1000 m. During storage, the highest organic acid content and the lowest respiration rate were observed in the fruit of both cultivars treated with peppermint, carob, and thyme oil, as compared to control fruit, respectively. To summarize, the use of EOs as postharvest treatment for apricot is recommended for maintaining the quality of the fruit during extended storage.

(Mdpi, 2021) Cavusoglu, Seyda; Yilmaz, Nurettin; Islek, Firat; Tekin, Onur; Sagbas, Halil Ibrahim; Ercisli, Sezai; Necas, Tomas
Various treatments are carried out in order to extend both the shelf life and storage life of fresh fruit and vegetables after harvest and among them non-toxic for humans, environmentally and economically friendly alternative treatments are gained more importance. In the current study, methyl jasmonate (MeJA), cytokinin, and lavender oil which are eco-friendly and safe for human health were applied on apricot fruit. The treated fruit were stored at 0 degrees C and 90-95% relative humidity for 25 days and catalase (CAT), superoxide dismutase (SOD), and ascorbate peroxidase (APX) enzyme activities and lipid peroxidation of apricots after treatments were studied. According to the findings obtained from the study, it was observed that 5 ppm cytokinin and 1000 ppm lavender oil treatments of apricot fruit gave better APX and CAT enzyme activity, respectively. In addition, better SOD enzyme activity in fruit was obtained with MeJA + lavender oil treatments. As a result, it can be emphasized that the product quality of apricot fruit is preserved as both the eco-friendly application of MeJA, cytokinin, and lavender oil separately from each other and the treatment of combinations between these compounds activate the enzymatic antioxidant defense systems of apricot fruit after harvest.

(Amer Soc Horticultural Science, 2011) Celik, Ferit; Ercisli, Sezai; Yilmaz, Suzan O.; Hegedus, Attila
Fruits of 11 cherry laurel (Laurocerasus officinalis L.) genotypes grown in a single location, Rise province, were analyzed for their fruit characteristics. Both physical and chemical characteristics of cherry laurel fruits were significantly influenced by genotypes. Fruit weight, the number of fruits per cluster, and flesh per seed ratio ranged between 1.87 and 4.01 g; 9.21 and 21.05, and 5.54 and 9.33, respectively. The genotypes R06 and R09 had the highest total anthocyanin [205 and 202 mg/100 g fresh weight (FW), respectively] and R06 and RI I had the highest total phenolic contents (503 and 481 mg/100 g FW, respectively). Total carotenoid and vitamin C contents ranged from 207 to 278 mg/100 g FW and 2.1 to 4.1 mg/100 g FW, respectively. Soluble solid content (SSC), crude fiber, crude protein, pectin, ash, and pH of genotypes fell between 9.64% and 17.10%; 0.44% and 0.85%; 1.44% and 2.09%; 0.20% and 0.47%; 0.25% and 0.71%, and 4.30 and 4.93, respectively. Data demonstrated that the great variations observed in the physical and chemical characteristics of individual cherry laurel genotypes might be explained by genotypic effect because all genotypes grew under the same ecological conditions. The investigated genotypes seemed to be perspective in health promotion.

(Mdpi, 2019) Karik, Unal; Nadeem, Muhammad Azhar; Habyarimana, Ephrem; Ercisli, Sezai; Yildiz, Mehtap; Yilmaz, Abdurrahim; Baloch, Faheem Shehzad
Laurel is a medicinally important plant and is known to the world for its essential oil. Turkey is the main market in the laurel leaf trade by sharing about 90% of the world trade. Here we made an effort to elucidate genetic diversity and population structure of 94 Turkish laurel genotypes collected from 26 provinces and four geographical regions using inter-primer binding site (iPBS) retrotransposon markers. A total of 13 most polymorphic primers were selected which yielded 195 total bands, of which 84.10% were found polymorphic. Mean polymorphism information content (PIC) was (0.361) and diversity indices including mean effective number of alleles (1.36), mean Shannon's information index (0.35) and overall gene diversity (0.22) revealed the existence of sufficient amount of genetic diversity in the studied plant material. Most diversity was found in genotypes collected from the Mediterranean region. Analysis of molecular variance (AMOVA) revealed that most of the variation (85%) in Turkish laurel germplasm is due to differences within populations. Model-based structure, principal coordinate analysis (PCoA) and neighbor-joining algorithms were found in agreement and clustered the studied germplasm according to their collection provinces and regions. This is a very first study exploring the genetic diversity and population structure of laurel germplasm using iPBS-retrotransposon marker system. We believe that information provided in this work will be helpful for the scientific community to take more interest in this forgotten but the medicinally important plant.

(Mdpi, 2021) Cavusoglu, Seyda; Uzun, Yusuf; Yilmaz, Nurettin; Ercisli, Sezai; Eren, Erkan; Ekiert, Halina; Szopa, Agnieszka
Button mushrooms have a very short shelf life after harvesting and are sensitive to mechanical damage and browning. This can be a severe problem in enlarging the market and the long-distance exportation of this product. In this respect, edible coatings could be an alternative treatment to extend the shelf life of button mushrooms, maintaining their quality during long-term storage. The aim of this study was to investigate the impact of gum, agar, sodium alginate, egg white protein, and lecithin on the postharvest weight loss, color, browning, respiration rate, ethylene production, and storage life of button mushrooms. The results showed that the above-mentioned edible coatings are a promising way to extend the life and maintain the quality of button mushrooms. Significant differences (p < 0.05) were observed between the control and edible coating-treated samples in all parameters. Sodium alginate and gum were more effective in preventing weight loss, coloring, and browning than other edible coatings. On the other hand, the respiration rate and ethylene production were more suppressed by the agar and lecithin coatings compared to the others. In conclusion, it can be recommended that the above-mentioned edible coatings could be used as novel coatings in commercial treatments for maintaining the quality of button mushrooms during a long-term storage period.

(Univ Agr Sci & veterinary Med Cluj-napoca, 2018) Celik, Ferit; Bozhuyuk, Mehmet Ramazan; Ercisli, Sezai; Gundogdu, Muttalip
In the present study, fruit weight, fruit firmness, external fruit color, soluble solid content, pH, titratable acidity, vitamin C, total phenolics, total anthocyanins and antioxidant capacity of eight wild bilberry grown in Coruh valley in northeastern Turkey were determined. The blueberry cv. 'Bluecrop' was also studied to make comparison with bilberry genotypes. Antioxidant activity of bilberry and blueberry fruits were comparatively assessed by FRAP (Ferric reducing antioxidant power) assay. Significantly higher contents of phenolics and anthocyanins were found in bilberry fruits comparted with blueberry fruits. However, blueberry cv. 'Bluecrop' exhibited higher fruit weight and vitamin C content than bilberry fruits. Total phenolic and total anthocyanin content was 327 mg gallic acid equivalent and 142 mg of cyanidin-3-glucoside equivalent in 100 g fresh fruit in cv. 'Bluecrop', while it was between 492-563 mg gallic acid equaivalent and 307-342 mg of cyanidin-3-glucoside equivalent in 100 g fresh fruits of bilberry accessions. Moreover, wild accessions had approximately 2-3 folds higher antioxidant capacity than cv. 'Bluecrop'. The obtained results suggest the possibility of improving the bioactive and antioxidant properties of bilberry cultivars by using wild ones in cross breedings. It was also concluded that genotypes significantly affect the bioactive content of fruits and consequently the possibility of using wild bilberry fruits as a potential source of natural antioxidants in food industry is worth to be considered.
