Turkish Journal of Agriculture and Forestry
Ten different Persian walnut cultivars were examined for their compositional data, including eight Hungarian and two introduced varieties. Oil content and fatty acid composition were determined, as well as oxidative stability (indicated by induction time). Antioxidative capacity, total polyphenol measurements, and individual phenolic compounds were also determined. Not only dry samples but fresh and stored samples were included in this study. Large differences were found among the varieties within these parameters, for example in oxidative stability, which contributes to antioxidative capacity. In conclusion, the nutritional value of Hungarian walnut cultivars was the same or even higher than those of foreign …
Variation In Needle And Cone Characteristics And Seed Germination Ability Of Abies Bornmuelleriana And Abies Equi-Trojani Populations From Turkey, Yusuf Kurt, John Frampton, Fikret Isik, Chal Landgren, Gary Chastagner
Turkish Journal of Agriculture and Forestry
Turkish fir (Abies bornmuelleriana Mattf.) and Trojan fir (Abies equi-trojani (Aschers. Et Sint. Ex Boiss) Mattf.) are economically and ecologically important endemic species to Turkey. These species are also becoming increasingly popular in Europe and North America due to their suitable characteristics for use as Christmas trees coupled with their pest resistance. Provenance features, as well as needle and cone characteristics and seed germination ability, of three Turkish fir and two Trojan fir populations were studied. Provenance features (vigor score, crown score, and color) and mother tree characteristics (height class, diameter at breast height, and height) were very similar between …

Turkish Journal of Agriculture and Forestry
In the present study, five different grapes varieties grown in Turkey were comprehensively characterized in terms of physicochemical properties, total bioactive content, antiradical activity, and volatile sugar compounds. Thermal degradation kinetics of anthocyanin in the selected grape varieties were also analyzed. All the bioactive compounds and antiradical activity varied depending on variety and grape part (skin, pulp, or seed). Higher amounts of total phenolics, total flavonoids, anthocyanin, and antiradical capacity were obtained from seeds. Fifty-nine volatile compounds were observed in the grape varieties. Terpenoid compounds were determined to be the predominant aroma compounds, of which limonene and citral had the …

Growth, oil yield, and carvacrol content in Thymbra spicata L. Var. Spicata microshoots were analyzed after 12 weeks of storage in MS media supplemented with elevated levels (0.0, 0.1, 0.2, 0.3, and 0.4 M) of three osmotic agents (sucrose, sorbitol, and mannitol) or ABA (0.0, 3.8, 7.6, and 11.4 μM). The obtained results revealed that using 0.2 M sucrose in the storage media yielded the best results in terms of growth reduction during conservation as well as maintenance of microshoot recovery at full capacity (100%) after conservation. Meanwhile, 0.1 M sorbitol or mannitol in addition to 3.8 μM ABA were …

Turkish Journal of Agriculture and Forestry
Ips sexdentatus (Boerner) and I. Typographus (Linnaeus) (Coleoptera: Curculionidae) are considered to be important destructive pests of coniferous forests in Europe and Asia. In this study, the efficacy of Beauveria pseudobassiana strain ARSEF 9271 isolated from Dendroctonus micans (Kugelann) (Coleoptera: Curculionidae) was evaluated against I. Sexdentatus and I. Typographus adults. Insects were treated with different conidial concentrations of the fungus to determine the virulence. A conidial suspension of 1 × 108 conidia mL-1 caused 100% mortality in both I. Sexdentatus and I. Typographus within 5 and 7 days, respectively. Additionally, 100% mycosis was obtained in the concentration-response experiments for both …

Turkish Journal of Agriculture and Forestry
Drought is a recurring problem of Jerusalem artichoke (Helianthus tuberosus L.) production under rainfed conditions. A better understanding of the responses of Jerusalem artichoke genotypes to drought can lead to the improvement of inulin content and inulin yield in Jerusalem artichoke and its production planning. The objective of this study was to compare the responses of five Jerusalem artichoke genotypes (JA60, JA125, JA5, JA89, and HEL65) to three water regimes (100% available water (AW; field capacity), 50% AW, and 25% AW) for inulin content and inulin yield.

Turkish Journal of Agriculture and Forestry
The Fertile Crescent is a primary center of wheat domestication and diversity. Despite its importance for bread wheat breeding, few efforts have been made to fully understand the genetic structure of the Anatolian bread wheat. A lack of information regarding the genetic structure of the bread wheat from this region is evident. Therefore, this study aimed to provide new insights into the genetic structure of bread wheat from Anatolia. A genetic linkage map was constructed based on recombinant inbred lines derived from a cross between the Turkish cultivar Gerek-79 and the Moroccan cultivar Arrehane, by using DArT markers anchored with …

Calosoma sycophanta L. (Coleoptera: Carabidae) is a voracious predatory beetle that feeds on several important lepidopteran pests. It is mass reared in laboratory breeding and released against forest pests. Any infection in this beetle is undesirable because it impacts production of effective and healthy beetles. In the present study, a microsporidian pathogen was found in C. sycophanta. Mature spores of the pathogen are single, uninucleate, oval, and small, measuring about 3.04 × 1.7 µm. The spore wall is 100 to 110 nm thick and consists of two layers: an electron-dense outer layer, the exospore (30-35 nm), and an electron-lucent inner …

Lead (Pb) is one of the most toxic and persistent elements, with no known biological role. High concentrations of lead enter saline soils through anthropogenic activities and industrial waste. The decontamination of Pb polluted sites through phytoremediation, especially by using woody plants, is an attractive approach. Eucalyptus camaldulensis is a good accumulator of Pb and a recommended tree species for reclamation of saline soils. However, there is very limited knowledge about the Pb-uptake behavior of Eucalyptus camaldulensis under saline conditions. The objective of this study was to examine the simultaneous impact of NaCl salinity and Pb stress on the phytoremedial …
