EVALUATION OF ALUMINUM STRESS INDUCED ANTIBACTERIAL AND ANTIFUNGAL ACTIVITIES IN ROMAN NETTLE

İbrahim İlker ÖZYİĞİT

In this current work, Roman nettle (Urtica pilulifera L.), a traditional medicinal plant that is very common and widespread species throughout Asia, Europe, and Northern Africa, was used as a model plant to investigate changes in antimicrobial activity following the application of aluminum stress. U pilulifera seedlings were grown in growth-room conditions and 0, 100, and 200 M AlCl3 were applied to the plants together with Hoagland solution (20 ml) for two months. The antimicrobial activities were tested against nine strains of bacteria (Salmonella sp., Staphyllococcus aureus, Escherichia col ...More

Some Heavy Metals and Mineral Nutrients of Narrow Endemic Cirsium Byzantinum Steud., From Istanbul, Turkey: Plant-Soil Interactions

İbrahim İlker ÖZYİĞİT | Gülbübü KURMANBEKOVA

Cirsium species have economic importance because of their botanical and medicinal properties. Thus, this study has aimed to investigate some heavy metal (Fe, Mn and Zn) and mineral nutrient (B, Ca, K, Mg and Na) status of narrow endemic Cirisum byzantinum. Plant and soil element concentrations were analyzed by using ICP-OES and the evaluation of plant-soil interactions for heavy metals and mineral nutrients were carried out by statistical methods. The measured element concentrations (in mg/kg) were in ranges of 5.936-19.044 for B, 1862.161-4811.168 for Ca, 12.610-38.474 or Fe, 3421.383-6881.88 ...More

INVESTIGATION OF POWDERY MILDEW DISEASE IN VARIOUS OAK (QUERCUS) TREES; A CASE STUDY FROM ISTANBUL/TURKEY

İbrahim İlker ÖZYİĞİT

Oak tree, with its different varieties, grows in almost all regions of Turkey. It is one of the wood materials valued for its timber. This noble tree is affected by powdery mildew (PM) disease, especially at its young ages. PM is a fungal disease infecting wide range of plant species as well as oak trees. It is quite harmful to nurseries, groves and coppice forests, and it reduces the quality and quantity of by-products. In this study, PM disease, its formation and spread conditions were investigated in various oak species populated in six different districts of Istanbul. Field observations, d ...More

DETERMINING ELEMENT ACCUMULATIONS IN TURKISH RED PINE USED AS A BIOINDICATOR FOR ESTIMATING OF EXISTING POLLUTION ON BOTH SIDES OF BOSPHORUS IN ISTANBUL

İbrahim İlker ÖZYİĞİT

Evergreen Turkish red pine tree shows wide distribution around Aegean and Mediterranean regions in Turkey. Herein work investigated the mineral nutrient status of Turkish red pine as a bioindicator for revealing the impact of existing pollution on both sides of Bosphorus in Istanbul. For this, Al, B, Ca, Cu, Fe, K, Mg, Na and Zn concentrations were determined in unwashed and washed leaves and barks of the plant and soil samples. The standard procedures were applied and the determinations of element concentrations in all samples were done using ICP-OES. The sample collections were performed at ...More

DETERMINATION OF NUT PROPERTIES AND CHEMICAL COMPOSITIONS OF WALNUT (JUGLANS REGIA L.) GENOTYPES GROWN IN WALNUT-FRUIT FORESTS OF KYRGYZSTAN

Ali Osman SOLAK | Kalıypa SALİYEVA | İbrahim İlker ÖZYİĞİT | Bakıt BORKOYEV

In this study, sixteen genotypes selected from walnut-fruit forests in the Osh and Jalal-Abad regions of Kyrgyzstan evaluated for nut properties and chemical composition. The nut traits such as nut dimension, nut and kernel weight, kernel ratio, and shell thickness were investigated. The ash, protein, oil, carbohydrate content and fatty acid composition of genotypes were also evaluated. The ranges of average nut characteristics determined for the selected genotypes were: 27.4-32.1 mm nut length; 23.8-28.6 mm nut width; 24.1-29.0 mm nut suture; 7.15-13.17 g nut weight; 3.26-5.65 g kernel weight ...More
