The effect of 24-epibrassinolide and 28-homobrassinolide on seed germination and seedling growth of radish (Raphanus sativus L.) was studied under cadmium toxicity. The impact of brassinosteroids (BRs) on free proline levels and the activity of antioxidant enzymes catalase (CAT; EC 1.11.1.6), peroxidase (POD; EC 1.11.1.7), superoxide dismutase (SOD; EC 1.15.1.1), ascorbic peroxidase (APOX; EC 1.11.1.11) and guaiacol peroxidase (GPX; EC 1.11.1.7) in radish seedlings under Cd toxicity was evaluated. The effect of BRs on the activity of ascorbic acid oxidase (AAO; EC 1.10.3.3) and lipid peroxidation in radish seedlings challenged with Cd stress...

A direct and secondary effect of liming and organic fertilization on the cadmium content in soil and in vegetables was examined. Celeriac (Apium graveolens L. var. rapaceum) was cultivated in the first year after lime application and organic fertilization whereas leek (Allium ampeloprasum ssp. porrum J. Gay) was grown in the next year. Soil was limed with a calcium carbonate fertilizer at the rate of 2.0 t CaO/ha. The following were applied as organic fertilizers: farmyard manure (60 t/ha), rye straw (4 t/ha), rye and winter vetch, both the plants cultivated as winter catch crops for green manure. Liming significantly...

The interactive relations of Al forms and the most important characteristics of Stagnosols were researched to diagnose which factors are the best to control the content of phytotoxic Al forms. The values of exchangeable Al (AlKCl) range from 0.0 to 560.7 mg/kg and increase with depth. The variation of exchangeable Al is high and it depends on the changes of all forms of soil acidity and the degree of base cation saturation. Their relation is best described by a non-linear function. The contents of total Al and Al extracted by ammonium oxalate in dark (Al amorphous, Aloxa) increase with depth, together with the increase of the...

Maize yield is severely affected by soil salinity. In an effort to engineer maize for improved salt tolerance, embryogenic calli of maize were co-bombarded with plasmids containing Oryza sativa Na+/H+ antiporter gene (OsNHX1) and bar genes. For the molecular analysis of putative transgenic samples, PCR, Southern and Northern blots were carried out. The maize plants over-expressing OsNHX1 accumulated more biomass when grown in the presence of 200mM NaCl in greenhouse conditions. Higher Na+ and K+ content was observed in transgenic leaves than in wildtype leaves when treated with...

Protein composition of the grain storage proteins (evaluation using electrophoresis in polyacrylamide gel - the SDS-PAGE method) and selected parameters of bread-making quality in a set of 6 winter wheat varieties from organic and conventional growing in Central Bohemia (elevation 295 m a.s.l.) were evaluated during a two-year experiment (2004 and 2005). In comparison with the varieties from organic growing, wheat varieties from the conventional growing were characterized by twice the percentage of High Molecular Weight (HMW) glutenins, responsible for dough elasticity (conventional wheat in average 25.22%, organic wheat 12.71%). At the same time,...
eFarmer - project "Bringing the datawarehouse for agriculture into practice"

The key focus of the project "Bringing the datawarehouse for agriculture into practice" is to develop an IT solution for the implementation of data integration in agriculture. This solution is elaborated in cooperation with a whole range of bodies in the Czech Republic; the lead partner is the Pardubice region where the pilot phase of datawarehouse implementation is being performed. Apart from Czech legal subjects, partners from Finland, Estonia and Poland are also participating in the eFarmer operation. The datawarehouse project is one of the biggest subprojects of the eFarmer operation and is directly connected to the subproject of "Analysis of data...
