The soluble proteins extracted from the first leaf tissues of cultivated tetraploid (Triticum durum Desf., genome AB) and hexaploid (T. aestivum L., genome ABD) wheat species and their diploid wild progenitors [T. monococcum L. (A), Aegilops speltoides Tausch (B), and Aegilops tauschii Cosson (D)] exposed to 100 mmol/l NaCl stress were separated by two-dimensional (2D) gel electrophoresis. There was no newly synthesized protein in the NaCl treatment compared to the control treatment in all species. However, protein profiles showed some differences among species. Most of these proteins had...

An alum-based drinking water treatment residue (DWTR) is the by-product from the production of potable water. Land application of DWTR has received a considerable attention for its potential as a low-cost disposal alternative. A greenhouse experiment was conducted to quantify the effects of DWTR on bioaccumulation of some heavy metals in plant tissue and to determine the effects of the DWTR on soil aluminum and aluminum phytotoxicity for the corn plants in alkaline soils. The results indicated that land application of DWTR significantly decreased extractable heavy metals in all studied soils. Combined analyses of all soils and rates of DWTR application...

A prerequisite to use organic fertilizers in a sustainable way is to quantify the amount of phosphorus and potassium available for plants that could be taken up by a crop. The objective of this study was to evaluate direct and subsequent influence of organic fertilizers addition (poultry manure and two types of composts) on the changes of bioavailability of phosphorus and potassium in soil and their accumulation in the aboveground oat biomass (Avena sativa L.) during three years. The available phosphorus and potassium contents in soil had a degressive trend during the years of experiment. The lowest contents of these elements in soil were found...

The main aim of this study was to determine the dependence of yield and selected soil properties on topography of the experimental field by using topographical data (elevation, slope and flow accumulation). The topography and yield data were obtained from a yield monitor for combine harvester, and soil properties data were taken from sampling points of our experimental field. Initially, the topographical parameters of elevation and slope were estimated and then the Digital Elevation Model (DEM) grid was created. On the basis of field slope the flow direction model and the flow accumulation model were created. The flow accumulation model, elevation...

Aquatic plants are known to accumulate heavy metals. In this study, Duckweed plants (Lemna polyrrhiza L.) were exposed to different concentrations of Cd and Pb. Various physio-biochemical parameters (fresh weight, chlorophyll content, soluble protein, soluble sugars, proline content and metal absorption) were studied. At lower metal concentrations, an increase in proline, protein and sugar was observed but at higher concentrations (above 30 mg/l) their decrease was noticed. Uptake of the metals was concentration and time dependent. Treatment with 1, 10 and 20 mg/l of Cd and Pb showed synergistic relation while 30 and 40 mg/l treatments showed...
