Genetic diversity was detected in 11 varieties of triticale registered in the Czech Republic by means of polymorphism of prolamin proteins using the PAGE ISTA method. The polymorphism of prolamin proteins allowed the differentiation of the individual triticale varieties in 2002 and 2003 harvests. On the basis of Dice's calculations of coefficients of similarity we discovered, in parallel with the uniform genotypes, genotypes with sister prolamin spectrums with a different percentage of participation in the respective years. A uniform spectrum was detected in the following varieties: Disco, Kolor, Lamberto, Marko, Presto, Sekundo, Ticino and Tricolor;...

Contamination of heavy metals in the environment is one of major concern because of their toxicity and threat to human life and the environment. Phytoextraction, using plants to extract heavy metals from contaminated soils is an emerging technology. In this work, in order to find a suitable plant species for use in cleaning up the soil in an industrial region, some crop species, which are cultivated by farmers on these soils, were studied. The effects of various concentrations of four heavy metals including Cd, Cr, Co and Ni were studied in two cultivars of wheat (Triticum aestivum L.), bean (Phaseolus vulgaris L.) and alfalfa (Medicago...

Extensive management (absence of management) of unfertilized permanent grasslands was examined for five years from the aspect of its influence on soil chemical properties of horizon A in a floodplain locality of the Crystalline Complex, in relation to water regime regulation, reclamations and liming. These treatments: without mowing (0), one cut (1) and two cuts (2) per year were used at sites without drainage (WD), with drainage (D) and with drainage water retardation (R). These average values were measured at all sites and for all treatments: content of soil organic carbon Corg 2.3-3.4%, combustible substances CS 12-15%, humic to fulvic...

Two methods developed by Prof. Dohányos and Doc. Zábranská from ICT in Prague (A) and Oxi Top Control AN 12 measuring system manufactured by MERCK Company (B), were used to determine the maximum yield of biogas and methane and the maximum rate of biogas and methane production per unit weight of biomass using buffered and macro- and micro-nutrient enriched grass biomass as a substrate. Statistical evaluation proved that the Oxi Top Control method did not provide significantly lower or higher results than the other method that is considered standard. Although the Oxi Top Control AN 12 method has a higher variance of measured values than the standard...
The influence of soil treatment by untreated and composted tannery sludge on yield, nutrient status, and chromium content in selected crops

The research is aimed to determine the effect of fertilization with untreated or composted tannery sludge on yielding, macroelement and chromium contents in plant biomass. The biggest yield diversification was observed in the first and second year of the experiment, whereas in the subsequent years no major differences in yields were discerned. The mechanism of diversified plant response to organic fertilizers supplied to the soil resulted from their different ability to utilize nutrients but was also due to crop succession and different tolerance of subsequent species to the amount of supplied chromium. Nitrogen contents in plants were diversified,...

Two high yielding wheat (Triticum aestivum L.) varieties were pollinated with seven agrarian superior varieties. F1's thus obtained were pollinated with diverse winter maize lines/composites and treated with a solution containing 2,4-D and GA3. The haploid embryos were rescued 13 to 16 days post pollination on MS1 and MS4 media. Out of 15, only two crosses viz., (UP 2338 × HD 2285) F1 × maize and (WH 533 × PBW 343) F1 × maize resulted in callus development and direct germination via embryo rescue.
