Unraveling The Impact Of Seed Fatty Acid Profiles On Spinach Seed Germination Under Temperature Stress, Mustafa Kaşka, Haluk Çağlar Kaymak
Turkish Journal of Agriculture and Forestry
Limited knowledge exists regarding the fatty acid profiles of spinach (Spinacia oleracea L.) seeds and their correlation with germination. This study aims to address this gap by thoroughly investigating these profiles and their relationship with seed germination. Therefore, the objectives include assessing how different temperatures influence seed germination in spinach cultivars, identifying tolerant cultivar(s) to temperature stress during germination, and exploring the relationship between fatty acid profiles and seed germination under varying temperature conditions. Nine spinach cultivars (‘Matador-1, 2, and 3’, ‘Ranchero F1’, ‘Aras F1’, ‘El Tajin’, ‘El Real’, ‘Catrina F1’ and ‘Poyraz F1’) were used as seed material. The …

Exposure to electromagnetic radiation (ER) with radio frequency is one of the environment's most common and fastest-growing human factors. Therefore, due to the increasing global growth of telecommunication towers and Wi-Fi waves, the possibility of positive or negative effects of Wi-Fi electromagnetic waves (WEW) is essential for the quality and quantity parameters of plants. An experiment was was carried out during the years 2020-2021 at the Research Farm of Tarbiat Modares University to investigate the effect of WEW on the grain yield, fatty acid composition (FA), oil content and antioxidant properties of camelina. Seeds were exposed to Wi-Fi electromagnetic radiation …

The objective of this study was to evaluate the performance of 3 environmentally friendly fertilizers and their effect on the growth of Chinese cabbage and its contents of bioactive compounds. The following fertilizers were applied: purslane extract, 5% sulfur, and 15% phosphoric acid with 5% calcium. A total of 9, 9, and 11 components were detected for fatty acids, carotenoids, and glucosinolates, respectively. The contents of cis-7 hexadecenoic acid, linoleic acid (C18:2n6c+t), and linolenic acid (C183n3) were generally increased, and also carotenoid amounts of violaxanthin, antheraxanthin, lutein, 13-cis-ß-carotene, α-carotene, ß-carotene, and 9-cis-ß-carotene were significantly increased by fertilizer treatments. All fertilization …

In this study, we aimed to compare fatty acid and volatile compound compositions of four rosehip species, namely Rosa pimpinellifolia, R. Villosa, R. Canina, and R. Dumalis, by gas chromatography with flame ionization detector (GC/FID) and headspace and immersion solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME/GC-MS and Im-SPME/GC-MS) techniques. The total lipid contents in fruits of the rosehip species varied from 5.83% (R. Villosa) to 7.84% (R. Dumalis). A total of 21 fatty acids were detected and quantified. In all species, except R. Canina, polyunsaturated fatty acids (PUFAs) predominated over saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs). Palmitic acid …
Solvent Optimization And Characterization Of Fatty Acid Profile And Antimicrobial And Antioxidant Activities Of Turkish Pistacia Terebinthus L. Extracts, Muhammed Zeki̇ Durak, Gülsüm Uçak
Solvent Optimization And Characterization Of Fatty Acid Profile And Antimicrobial And Antioxidant Activities Of Turkish Pistacia Terebinthus L. Extracts, Muhammed Zeki̇ Durak, Gülsüm Uçak
Turkish Journal of Agriculture and Forestry
The present study investigated 12 different Pistacia terebinthus L. (terebinth) fruits, harvested or purchased in Turkey, for fatty acid composition, radical scavenging, antimicrobial activity, and total phenolic content. Solvent optimization for the samples was prepared by using a simplex lattice mixture design prior to the analysis. The optimum solvent mixture was 39% water and 61% acetone, based on the maximization of extraction yield of phenolic compounds. Total phenolic contents (TPCs) of the extracts varied from 12,189 mg GAE/1000 g extract to 36,392 mg GAE/1000 g extract. 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities of the extracts varied over a wide range (8.86%-64.43%) …

Helianthus annuus is one of the most important oil species, with a comparatively narrow genetic base. The development of new sunflower cultivars is the focus of many research and breeding programs. Intergeneric hybridization between H. annuus and Echinacea purpurea, a valuable medicinal plant, has not yet been utilized in cultivar development. This paper describes 2 advanced hybrid lines produced from an intergeneric cross between the cultivated sunflower inbred line 6650 and an accession of E. purpurea. The hybrid plants have successfully been grown in the field. The hybrids, showing expression of traits from both parental species, were intermediate between both …
