Four maize hybrids bred at the Cereal Research Non-Profit Company in Szeged were registered at the National Institute for Agricultural Quality Control (OMMI) during the period 2001-2004. The registration of five Szeged hybrids is expected on the territory of the European Union in 2005-2006. The hybrids are accompanied by specific production technological guides for commercial production based on the results of agronomy trials, so that the genetic potential of the hybrids can be utilised in practical farming to the highest possible extent. The specific agronomic traits of hybrids with different vegetation periods and genotypes are investigated. If a maize hybrid is to be recommended to farmers, it is necessary to know not only its yield potential, but also its yield stability. For this reason, investigations are also made on the effect of soil and climate on the grain yield potential of each hybrid individually.

Abstract  

Hybrid materials were prepared by γ-irradiation of a mixture of polydimethylsiloxane (PDMS), with tetraethylorthosilicate (TEOS) and zirconium propoxide (PrZr), using a 60Co γ source, without any addition of solvents. Thermogravimetry, differential scanning calorimetry and X-ray diffraction measurements showed that the obtained hybrids are amorphous materials of the nanocomposite type. The results highlighted the different influence of each of the metallic alkoxides on the hybrid structure. The material rupture temperature, associated with the degradation of the organic component, depends mainly on the TEOS content, whereas the inorganic component structural stability depends on the relative PrZr content in the alkoxides mixture.
