DETERMINATION OF THE NATURAL ENEMIES AND POPULATION FLUCTUATION OF Tuta absoluta (MEYRICK, 1917) (LEPIDOPTERA:GELECHIIDAE) IN HIGHLAND GREENHOUSES IN ANTALYA, TURKEY

Hüseyin GÖÇMEN

Tomato leafminer Tuta absoluta (Meyrick) is one of the most important pests that cause yield and quality loss in tomato cultivation in greenhouse and open field. 7'. absoluta, has spread rapidly in tomato production areas after emerging to Turkey in 2009. The pest is widely found along growing season in greenhouses and open fields in the coastal part of Antalya, where suitable climatic conditions are present. However, the population status of T. absoluta in tomato cultivation in greenhouses under high altitude highland conditions is not known and the study has been handled for this purpose. th ...Более

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 ...Более

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 ...Более

A Research on the Determination of Molecular Genetic Characteristics of Some Bemisia Tabaci (genn.) (hemiptera:aleyrodidae) Populations

Hüseyin GÖÇMEN

The whitefly Bemisia tabaci (Gennadius) (Hemiptera, Aleyrodidae) is one of the most crucial agricultural pests in tropical and subtropical regions. The pest is a species complex which contain morphologically indistinguishable biotypes or genetic groups. The aim of the present study is to examine B. tabaci populations collected from Aydin, Antalya, Mersin, Adana and Hatay regions in 2004 and 2005. Prior to analysis, as the first step, the biotypes were determined by considering molecular differences among populations. In addition, the differences among populations were determined by means of bi ...Более

GENETIC DIVERSITY AND PHYLOGENETIC ANALYSES OF TURKISH RICE VARIETIES REVEALED BY ISSR MARKERS AND CHLOROPLAST trnL-F REGION

İbrahim İlker ÖZYİĞİT

A set of 17 Turkish rice (Oryza sativa L.) varieties (TRVs) were characterized using inter simple sequence repeat (ISSR) markers to study genetic diversity. Also, the sequences of trnL((UAA))-F-(GAA) intergenic spacer (IGS) regions were used to evaluate the phylogenetic relationships of TRVs. According to ISSR data, the observed number of alleles (Na), effective number of alleles (Ne), Nei
