Tobacco, Nicotiana tabacum L., var. Wisconsin 38 as the control (WSC), and four genetically modified lines of the same variety, were tested for Cd, Zn and Ni accumulation. Genetically modified lines of the same variety, bearing the transgene CUP1 (gene coding a yeast metallothionein), GUS (reporter gene for ß-glucuronidase), HisCUP (CUP combined with a polyhistidine tail), and HisGUS (reporter gene for ß-glucuronidase, combined with a polyhistidine tail) under a constitutive promoter, enabling it to follow the heavy metal tolerance and uptake changes as a function of the transgene present. Control and transgenic lines were tested...

Information on the availability of P following compost addition to soil may help to a better management of P fertilization of the crop in respect to plant growth and the environment. Therefore a greenhouse experiment was conducted to investigate the effect of compost within the official classes of stability III and V on growth and P exploitation of ryegrass (Lolium perenne L. cv. Turilo). The following result was obtained: As compared to a control without P application, compost application resulted in a significant yield increase. Application of composts of the official class of stability V resulted in higher yields as compared with the application...

The Příbram region belongs to the most polluted areas in the Czech Republic. Atmospheric deposition of potentially toxic elements from lead smelter represents the main source of contamination in this region. In this study, the most polluted location intensively used for agriculture situated northeast from the source of contamination was investigated. The individual sampling points were positioned by GPS and representative samples were taken from 0-60 cm split into three20 cmlayers. In the soil samples total Pb and Cd contents, plant available contents of these toxic elements and soil pH were determined. The total Cd content at the investigated site...

Hydromorphy is a major soil fertility constraint in Europe and North America causing specific nutritional imbalance in soils and crops. The objectives of this study were to examine the differences among maize hybrids in phosphorus (P), zinc (Zn), manganese (Mn) and iron (Fe) status in leaves, and to investigate the interrelationship among these micronutrients as well as the interrelationship between Zn and P on hydromorphic soil in Eastern Croatia. Twenty maize (Zea mays L.) hybrids were grown under field conditions of Eastern Croatia in a period of two years. Considerable differences in mean ear-leaf Zn, Mn and Fe contents at silking stage...

The effect of dimethylarsinic acid (DMA) on the growth of radish and the content of As compounds in roots and leaves of the radish were investigated. Radish was grown in pots in three soils (Fluvisols, Chernozems and Luvisols) amended with 20 mg As/kg of soil in form of DMA. Behavior and transformations of DMA in the soils differed depending on the individual soil type. In the first season, plants grew up at Luvisols only. In the second season the plants were able to grow at Luvisols and Chernozems, too. The roots and leaves of radish from Luvisols had DMA as the dominant arsenic compound present (~ 90% in the extract) in the first season. In the roots...

The investigation is focused on the illustration of the temporal changes in spatial variability of the Mehlich III available phosphorus, potassium and magnesium in the 10.5 hapart of the whole 54 hafield, located near Český Brod. Soil is characterized as Orthic Luvisol. To estimate temporal variability of available nutrients, soil samples were taken in 2001-2003 four times per year (twice in spring and twice in the autumn periods). For the description of field variability of selected soil parameters coefficient of variation (CV), experimental variograms with fitted models and relative nugget effect parameters have been used. Three year results...
