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 ...Daha fazlası
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 ...Daha fazlası
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
