Under the light of these scientific findings, vermicompost tea might be used as an organic bio stimulant for efficient callus growth and complementary to commercial chemical hormones in sainfoin. This research is important due to it can contribute positively to the plant species that are difficult in terms of callus growth and plant regeneration in tissue culture.

Consumption of fermented products rich in antioxidants, anti-inflammatory, anti-diabetes, anti-obesity and anti-carcinogenic compounds is growing into a key strategy to fortify antioxidant defense system. Cabbage products produced by lactic-acid fermentation are chosen via their special microbiota. Considering these special medical properties of fermented-cabbage products as pickled cabbage, sauerkraut and kimchi were produced and evaluated. The data demonstrated that pickled cabbage (109.89±4.74 mg ascorbic acid/100 g d.w.) and its brine (208.14±17.29 mg ascorbic acid/100 g d.w.) exhibited the highest vitamin C content, followed by kimchi (77.42±2.87 mg ascorbic acid/100 g d.w.). The highest total phenolic content was detected in kimchi and sauerkraut with 869.64±70.16 and 438.257±25.05 mg gallic acid equivalents/100 g fresh weight (f.w.), respectively. 50% of the scavenging effect (EC50) values of free radical scavenging activity (DPPH) in kimchi 14.6 mg/ml, followed by sauerkraut (15.52 mg/ml) and pickled cabbage (18.88 mg/ml). Results demonstrated that fermented cabbage products have a great potential with content of bioactive compounds, high antioxidant features promising high beneficial impacts.

Ethanol, chloroform and hexane extracts from plants namely Urtica dioica L., Mentha piperita, Thyme serpyllum and Chenopodium album L. were evaluated for their total phenolic and total flavonoid contents, antioxidant and antibacterial efficiencies. The antioxidant activities were screened utilizing DPPH radical scavenging activity, ABTS scavenging activity, CUPRAC activity and total antioxidant capacity. Antibacterial activity of the tested extracts was determined by disc diffusion and broth dilution methods. U. dioica and C. album extracts showed varying activities against the test bacteria. The hexane extracts of T. serpyllum and C. album showed the weakest copper reducing antioxidant capacity (CUPRAC) activity. 2,2-diphenyl-1picrylhydrazyl (DPPH) activity of the solvents are increased in the following order: Ethanol>Chloroform>Hexane. Our results revealed that all of the tested plants might be an alternative to synthetic antioxidant and antibacterial agents.

Main aim of this study was to determine the effects of different salt contents (75 mM, 150 mM and 225 mM NaCl), heavy metal (0.2 mg/L FeCl3, NiCl2, ZnCl2), lime (2 mg/L CaCO3), drought (50%) and pollution (0.2 mg/L dust of factories) on photosynthetic pigments, malondialdehyde (MDA), hydrogen peroxide (H2O2) levels, the ascorbate peroxidase (APX), catalase (CAT), guaiacol peroxidase (GPOX) and superoxide dismutase (SOD) in Siyez wheat (Triticum monococcum L.). All experiments were carried out under laboratory conditions with 16 hour-day and 8 hour-night photoperiod in an incubator at 23 ± 1°C. Results showed that mean chlorophyll-a concentration was highest in the siyez seedlings treated with the pollution, while both mean chlorophyll-b and total chlorophyll concentrations were highest with 75 mM salt application. Mean total carotenoid was, however, highest with the drought treatment and mean relative water content was highest with NiCl2 application. Mean MDA and H2O2 contents were found to be highest in the siyez seedlings treated with 225 mM salt, whereas they were lowest with NiCl2 treatment. Mean proline content was highest with the NiCl2 treatment compared to the lowest concentration in the control siyez seedlings (82 µmol/g). Mean APX, CAT and GPOX activities were noted to be highest in the siyez seedlings treated with NiCl2. In general, the siyez seedlings showed high tolerance to the pollution, NiCl2 and drought with having highest photosynthetic pigments, proline, protein content and enzymes activities. Among all treatments, 225 mM NaCl and CaCO3 negatively influenced chemical compounds of the siyez seedling. When all data are taken into consideration, it can be said that higher photosynthetic pigments, proline contents, antioxidant enzymes activities and lower MDA and H2O2 levels play an important role in the resistance of siyez seedlings against abiotic stress conditions.

In this study, variation of some chemical components such as anthocyanin, β-carotene, lycopene, phenolic, nitrate, soluble protein, proline, glucose, sucrose and total carbohydrate level ad PAL activity in some wild and cultivated edible mushrooms was examined. For this, four different mushroom species (Agaricus campestris L., Cantharellus cibarius Fr., Hericium erinaceus (Bull.) Pers., Lactarius piperatus L. Pers) were supplied from local market, named Kuzeykent Semt Bazaar, in Kastamonu province of Turkey. Mushroom samples were collected from Araç, Daday, Devrekani and Tosya locations of Kastamonu. According to findings, the highest anthocyanin value and PAL activity were obtained from A. campestris collected from Arac location with 0.107 mg g-1 and 6.99 EU, respectively. The amount of β-carotene (2.297 mg g-1) and lycopene (0.644 mg g-1) was the highest in C. cibarius collected from Tosya location, however; proline, soluble protein, nitrate and glucose level were the maximum in A. campestris collected from Devrekani location with 149.61 µmol g-1, 55.49 mg, 159.963 mg g-1 and 29.36 µg g-1, respectively. While total carbohydrate was the highest in H. erinaceus collected from Araç location with 80.97 µg g-1, sucrose concentration was the maximum with 39.22 mg g-1 in H. erinaceus collected from Daday location. As a result, A. campestris collected from Devrekani location exhibited the highest nutrient in terms of chemicals analysed except anthocyanin and it was followed by H. erinaceus collected from Daday location. However, C. cibarius and H. erinaceus collected from Araç location had lower chemical components. It can be said that these mushroom species are valuable and important as major food sources and non-wood products for Kastamonu province.

Highly digestible high-lysine (HDHL) sorghum-wheat composites have previously been shown to produce better composite dough and bread compared to normal sorghum-wheat composites. This study aimed to test whether improved HDHL lines can provide further enhanced functionality through the effects of transglutaminase (TG) enzyme to improve dough rheological properties. Sorghum-wheat composite doughs were made using HDHL and normal sorghum flours at substitution levels of 10, 20, and 30%, with and without 0.15% TG. Rheological properties of dough were tested using a mechanical spectrometer at 0.05% strain amplitude (within the linear viscoelastic region) over a 0.01- 50 rad/sec frequency range. A more elastic system was observed in HDHL sorghum-wheat composites above 10% substitution levels compared to normal sorghum-wheat composite dough. Addition of TG to HDHL sorghum-wheat composites resulted in a decrease in phase angle values at all substitution level, indicating that TG increased the dough elasticity. However, TG did not change viscoelastic properties of normal sorghum-wheat composites. Bread from HDHL sorghum-wheat composites had significantly higher (P
