Hazelnuts are widely employed in various dietary practices, making them one of the most frequently utilized nuts. This study morphologically, chemically, and molecularly characterized a new hazelnut genotype throughout the 2018 to 2020 growing seasons. The variety burst leaf buds between 10th and 15th April and reached harvest maturity between 5th and 15th September. The genotype bore a mean of 2.33 nuts per cluster, with the majority of clusters consisting of double and triple nuts. The means of the nut weight was 2.38 g, the kernel weight was 1.35 g, the kernel ratio was 56.81%, the shell thickness was 0.96 mm, the nut size was 18.32 mm, the kernel size was 14.77 mm, the good kernel ratio was 91.7%, the protein content was 13.5%, the oil content was 55.8%, the oleic acid ratio was 81.43%, and the linoleic acid ratio was 10.68%. The genetic similarity rate between the new hazelnut genotype and the standard Çakıldak, Palaz, Tombul cultivars, as well as randomly selected Çakıldak hazelnut clones from the region, ranged from 0.58 to 0.98. Additionally, the polymorphism rate varied from 45.5 to 100%. On average, the investigated hazelnut genotype exhibited a genetic distinctiveness of 38% compared to randomly selected Çakıldak clones from the same region, and 47% compared to standard hazelnut cultivars. Consequently, this genotype could serve as valuable genetic material for hazelnut breeding programs through genetic distinctiveness and promising nut quality, and could potentially be registered as a new cultivar.

This research was carried out to determine the relationships between pomological characteristics of hazelnuts collected manually from the branch and the ground. The research was carried out in three different orchards belonging to a producer, which contains Tombul, Foşa and Çakıldak hazelnut varieties in Kocaali district of Sakarya province (Türkiye). The orchards, located at an altitude of 300 m, face north. Hazelnut samples of Tombul, Foşa and Çakıldak varieties were collected from the branch in the first (2009) and second year (2010), on 12-15 August, 15-18 August and 22-25 August, respectively, and from the ground on 24-27 August, 27-30 August and 4-7 September, respectively. Nut weight, nut size, shell thickness, kernel weight, kernel size, kernel cavity, kernel percent, shriveled kernel ratio, good kernel ratio, full and average blanching ratios were determined in dried fruits. Correlation analysis was performed between the properties examined separately in the two groups of samples. In the samples collected from the branch and the ground, the highest variation was seen in the shriveled kernel ratio and the lowest in the good kernel ratio. It was determined that all of the significant correlation coefficients in the samples collected from the branch were positive, and the highest correlation coefficients were between full blanching ratio-average blanching ratio, nut weight-kernel weight and nut size-kernel size, respectively. In the samples collected from the ground, more significant correlations, and also negative significant relationships were found between the investigated properties. It was determined that the highest positive correlations were found between nut size-kernel weight, nut weight-kernel weight, full blanching rate-average blanching rate, nut weight-kernel size and nut sizekernel size, respectively; the highest negative correlations were found between the shell thickness-good kernel ratio, the shell thickness-kernel size, and the shriveled kernel ratiogood kernel core ratio, respectively. It can be said that the samples collected manually from the ground in hazelnut were more homogeneous than those collected from the branch in terms of the quality characteristics examined; in the samples collected from the ground, the good kernel ratio and kernel size were negatively affected by the shell thickness, the shriveled kernel ratio was positively affected, and there were no differences between the samples in terms of other relations.

The overall goal of this work was to determine the effects of Polyphagotarsonemus latus (Banks) (Trombidiformes: Tarsonemidae) infestation on the physicochemical contents of fresh tea leaves and tea yield under field conditions in Rize province (Black Sea Coast, Turkey). The study was carried out on Muradiye–10, Pazar–20, and Tuğlalı–10 tea clones. Water extract, dry matter, caffeine, total polyphenol, crude cellulose, and total ash were analyzed as physicochemical parameters in the fresh tea leaves. The findings indicated that the yield of Muradiye–10 was significantly reduced with the increase in infestation of P. latus. Dry matter content in all clones showed a reduction when the shoots were infested by P. latus. Although the water extract values generally remained unchanged, the infested leaves of Pazar–20 had a higher amount of water extract than the uninfested leaves. On the other hand, the polyphenol content was not affected by mite feeding. The total ash, crude cellulose, and caffeine contents showed unsteady changes. Their values either increased, decreased, or remained unchanged considering the years, clones, and mite densities. We conclude that the infestation of P. latus generally deteriorated the physicochemical contents of fresh tea leaves as well as fresh tea yield, although it changes over the years, clones, and mite densities.

The Black Sea region of Turkey is where the Medlar population is most common, and Medlar usually grows naturally in this region. This study was carried out to determine the organic acids, sugars and bioactive compounds of promising Medlar (Mespilus germanica L.) genotypes which were grown in Tonya and Sürmene districts of Trabzon province (Black Sea Region of Turkey) in 2017 and 2018. Total of 15 genotypes were evaluated in the study, including 8 genotypes from Sürmene and 7 genotypes from Tonya. As a result, crude protein was ranged from 1.65 to 2.70%, crude oil from 0.10% to 9.40%, soluble solids contents from 9.80% to 20.20%, titratable aciditty from 0.60% to 1.40%, ascorbic acid from 21.5 mg 100 g−1 to 44.2 mg 100 g−1, malic acid from 590.5 mg 100 g−1 to 1074.5 mg 100 g−1, succinic acid from 127.0 mg 100 g−1 to 419.0 mg 100 g−1, and citric acid from 2.0 mg 100 g−1 to 32.0 mg 100 g−1, fructose from 3255 mg 100 g−1 to 4726 mg 100 g−1, glucose from 2108 mg 100 g−1to 3017 mg 100 g−1, sucrose from 127 mg 100 g−1 to 399 mg 100 g−1, carbohydrate from 47.3% to 73.1%, total phenolics from 41 mg GAE 100 g−1 to 411 mg GAE 100 g−1 and antioxidant activity 13.1 mmol TE 100 g−1 to 77.8 mmol TE 100 g−1. It was found large diversity regarding crude oil, SSC, titratable acidity, citric acid, glucose and antioxidant capacity of fruits among the genotypes. It can be said that the fresh fruits of promising Medlar genotypes are particularly promising for the use of nutraceuticals. In particular, Ton-20 and Ton-21 genotypes were remarkable due to their high-quality characteristics and total phenolic content. [ABSTRACT FROM AUTHOR]

This study was carried out to determine the changes in yield and some quality characteristics of 'Tombul' and 'Palaz' hazelnut cultivars according to orchards varied in terms of photosynthetic active radiation. The study was carried out in three orchards with full day sun lighted (100% PAR), half day sun lighted (66.34% PAR) and shady (49.93% PAR) in the Fatsa district of Ordu province (Turkey) in 2016. The experiment was designed in random blocks and three replicates. As a results, it was determined that lighting conditions of the orchards have a significant effect on yield and quality traits in both cultivars. As the sun lighting decreased, yield and good kernel rates decreased; blank nut ratio increased. In addition, the oil content was decreased as the lighting in the orchards increased but it was found to be significant only in 'Tombul' hazelnut cultivar. As a result, it may be recommended to take into consideration the natural lighting conditions of the orchards in the new plantations, not to plantation the orchard in places that do not have any sunlight and to apply the cultural practices in existing orchards to get enough light.

Polyphagotarsonemus latus (Banks) (Acari: Tarsonemidae) is a serious pest to a variety of agricultural crops including tea (Camellia sinensis (L.), Theales: Theaceae) worldwide. In this study, the potential of Amblyseius (Neoseiulus) californicus (McGregor 1954) and Amblyseius swirskii (Athias-Henriot) (Acari: Phytoseiidae) at two initial release ratios, 1:10 and 1:20 (predator: prey), and the effect of the garlic (Allium sativum L., Alliaceae) bulb extract, tobacco (Nicotiana tabacum L., Solanaceae) leaf extract and soft soap in the management of P. latus were assessed. The research was carried out on seedlings of Tuğlalı-10, Muradiye-10 and Gündoğdu Turkish tea clones in Rize province (Black Sea coast, Turkey) during two growing seasons in 2013 and 2014. For each clone, a completely randomized block design was used to compare the differences among the nine treatments and two controls (sprayed and unsprayed). 80 % Micronized Sulfur was used on the sprayed control plot. Results showed that A. swirskii and N. californicus may be effective in reducing P. latus densities at the initial predator: prey release ratios of 1:10 and 1:20 on tea plants under Rize conditions. The tobacco leaf, garlic bulb extracts and soft soap treatments were also found to be promising for controlling P. latus on tea plantation. [ABSTRACT FROM AUTHOR]

ABSTRACT The aim of this study is to evaluate the content of phenolics such as quercetin, chlorogenic acid, caffeic acid, p-coumaric acid, ferrulic acid, as well as other catechin, epicatechin and quercetin-3-rutinoside (rutin). Phenolic compounds were measured by spectrophotometric methods. Among the researched apricots, Organically grown cultivar contained the highest amounts of all groups of phenolics, followed by conventional apricots. The quantity of polyphenols depended on sulfurization was investigated. It is found that the region of cultivation did not have remarkable influence on polyphenol, whereas the cultivation type has the main effect. Significant differences were observed in phenolic mass fraction among different cultivars and growing seasons ( P < 0.05), and phenolic compounds were significantly higher in all organics. Examined cultivars possess high antioxidant capacity and reducing power, and all phenolics were highly correlated with RP ( R = 0.46 to 0.99). Generally, organically grown fruits are rich sources of phenolics, which show evident antioxidant capacity. The high-pressure liquid chromatography, equipped with diode array detector, was used to investigate the polyphenols. We state that the level of all determined phenolics decreased after sulfurization. PRACTICAL APPLICATIONS Consumption of apricots have been applied to be a practical approach toward the prevention of several degenerative diseases. It is well reported that apricots with different cultivars contain phenolics that have been shown to be the main phytochemicals present in fruit and that they play important roles in the preservation of several degenerative diseases. Sulfurized apricots have much better hygienic quality, and due to chemical reactions during processing, they become more digestible and have a decreased nutritional value. However, sulfurization may affect the antioxidant status of apricots due to the release of more phenolic compounds and destruction or creation of redox-active metabolites. [ABSTRACT FROM AUTHOR]
