This study compared the extraction efficiency of 3 different techniques, ultrasound-assisted extraction (UAE), microwaveassisted extraction (MAE), and the classical extraction method, in obtaining some bioactive and allergen compounds, namely liquiritin (LQ), glycyrrhizin (GL), glycyrrhetinic acid (GA), and carbenoxolone (CBX), from liquorice samples of Glycyrrhiza glabra grown in Turkey. Extraction parameters for each technique were optimised by the response surface methodology-central composite design approach. Concentrations of LQ, GL, GA, and CBX, which were selected as the responses of selected independent variables, were determined by liquid chromatography-electrospray ionisation tandem mass spectrometry. One-way variance analysis was performed to evaluate the significance of the …

Macro- And Micromineral Contents Of Different Quinoa (Chenopodium Quinoa Willd.)Varieties Used As Forage By Cattle, Mustafa Tan
Turkish Journal of Agriculture and Forestry
Mineral deficiencies or mineral excess affect livestock production in most regions of the world. For this reason, it is important to know the mineral contents of forages used in animal feeding. Quinoa (Chenopodium quinoa Willd.), which has become a popular grain crop around the world in recent years, is used as forage in animal feeding. This study was carried out to determine the contents of macro- and microminerals and mineral balance in 9 different quinoa varieties. The results of the study indicated that mineral contents of forages show great variation between quinoa varieties. The Cherry Vanilla variety is rich in …

The regulation of auxin (indole-3-acetic acid, IAA) level in plants is a complex mechanism and the concept is not completely understood. There are many lines of evidence suggesting that amino acid conjugates of IAA play a vital role in auxin homeostasis, but the involved plant enzymes are still under investigation. In the present study, the alteration in the levels of auxin and its conjugates in the different physiological stages and organs, as well as its role in flower bud abscission in Pistacia vera L., were investigated. The levels of the auxin and its conjugates, such as IAA, indole butyric acid …

Turkish Journal of Agriculture and Forestry
Forest inventory (FI) is the most challenging stage of forest management and planning process. Therefore, in situ surveys are often reinforced by modern remote sensing (RS) methods for collecting forestry-related data more efficiently. This study tests a stateof- the-art data collection method for practical use in the Turkish FI system for the first time. To this end, forest sampling plots were conventionally measured to collect dendrometric data from 437 trees in Artvin and Saçınka Forest Enterprises. Then, each plot was scanned using a handheld mobile laser scanning (HMLS) instrument. Finally, HMLS data were compared against ground measurements via basic FI …

Seed Biopriming Mitigates Terminal Drought Stress At Reproductive Stage Of Maize Byenhancing Gas Exchange Attributes And Nutrient Uptake, Hamid Nawaz, Nazim Hussain, Moazzam Jamil, Azra Yasmeen, Asad Bukhari, Muhammad Auringzaib, Muhammad Usman
Turkish Journal of Agriculture and Forestry
Maize (Zea mays L.) is an important cereal crop around the globe. Scarcity of water is one of the major abiotic factors reducing yields in this crop. The development of maize varieties with stress-tolerant traits is time-consuming and laborious work. There is a strong need to develop techniques that could have the effect of reducing irrigation requirements and mitigating waterstress conditions. Biopriming (seed priming with bacterial inoculation) is a newly emerging, simple, and easily adaptable strategy to mitigate drought stress for enhanced crop production. The current trial was executed using a randomized complete block design with factorial arrangements during the …

The Effects Of Wheatgrass Length On Antioxidant Activity And Total Phenolic Content Inwheatgrass (Triticum Spp.), Yusuf Şavşatli
Turkish Journal of Agriculture and Forestry
This study was carried out with the aim of determining the effects of wheatgrass lengths on antioxidant activity and total phenolic content of wheatgrass belonging to different cultivars (Triticum spp.) in laboratory conditions in 2017. When the wheat seedlings grown in plastic containers under soilless conditions reached three levels of wheatgrass length (5-6, 8-9, and 11-12 cm), the seedlings were cut from the root collar and dried in an oven. As a result of analysis of the dried material, it was found that the cut lengths of wheatgrass significantly (P < 0.01) affected antioxidant activity and total phenolic content of wheatgrass. Ten wheat cultivars belonging to Triticum monococcum L., T. durum L., and T. aestivum L. were used. Wheatgrass was cut at three lengths (5-6, 8-9, and 11-12 cm). It was found that the wheatgrass lengths had a significant (P < 0.01) effect on antioxidant and total phenolic content of wheatgrass. In addition, in terms of these traits, the most suitable wheatgrass length for cutting changed depending on the wheat species and also cultivars. The highest (P < 0.01) antioxidant activity and total phenolic content (TPC) were also determined at three wheatgrass lengths in cultivar Sarıbaşak. The average values obtained from Sarıbaşak wheatgrass were 31.0% for DPPH-free radical scavenging activity and 51.6 mg GAE-1 dry weight for TPC. The results of the analysis suggested that Sarıbaşak is the most promising cultivar in terms of both antioxidant activity and TPC in wheatgrass.

Although studies on tolerance to abiotic stress conditions in cabbage species and varieties have been carried out, these studies have generally been conducted in field and greenhouse pot experiments. In such studies, morphological measurements and evaluations have been made. However, there are deficiencies in physiological and molecular detection studies. Therefore, this study focused on detecting any DNA methylation change in the genome of cabbage seedlings when NaCl (salt stress) in combination with putrescine (Put) was applied. Different concentrations of NaCl and Put were applied to white head cabbage (Brassica oleraceae L. cv Yalova-F1). Germination rate, root length, shoot length, seedling …
