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 ...Более

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 ...Более

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 ...Более
