  • Correlations study between the selenium content of wheat grass (Triticum aestivum L.) and wheat seeds grown on different soil types

    In the course of the research we determined selenium and dry-matter content of 35 wheat grasses and 35 wheat seeds. The selenium content of the preparation plant samples was measured by spectrofluorimetric determination (ʎexcitation=380 nm, ʎemission=519 nm) of the resulted piaz-selenol complex. It was established that between the selenium content of the wheat grass and wheat seed the correlation coefficient was 0.36 at p=0.05 level which indicates a medium close correlation. Similarly, there was a medium close correlation between selenium content of the wheat grass calculated on dry-matter basis and total selenium content of the wheat, with a correlation coefficient of 0.40 at p=0.02 level.

  • Study on the cold tolerance of maize (Zea mays L.) inbred lines in Phytotron

    Maize has come a long way from the tropics to the temperate zone. In the beginning, the spreading of maize was prevented by its sensitivity to cold. Improved cold tolerance at germination is one of the most important conditions for early sowing. The advantage of cold tolerant hybrids is that they can be sown earlier, allowing longer growing seasons and higher yields, due to the fact that the most sensitive period in terms of water requirements, flowering, takes place earlier, i.e. before the onset of summer drought and heat.

    In Martonvásár, continuous research is carried out to improve the cold tolerance of maize. In the present experiment, the cold tolerance of 30 genetically different maize inbred lines was investigated in a Phytotron climate chamber (PGV-36). The aim of our research is to identify cold tolerant lines that can be used as parental components to produce proper cold tolerant hybrids and/or as sources of starting materials for new cold tolerant inbred lines. After observing and evaluating changes in phenological traits under cold-test, the results of the cold-tolerance traits of interest have been used to highlight several inbred lines that could be good starting materials for further research on genetic selection for cold tolerance.

  • Analysis of integrated, quality and environment focused management practices in the Forage Industry Ltd, Bábolna

    The significance of the effect of agricultural activities on the environment was focused on later than that of industry; however, today, an increasing number of companies using an environmental management system (EMS) has been registered in this sector, too. In the agricultural sector, EMS according to ISO 14001 was introduced first in the forage industry by Bábolna Takarmányipari Kft. In our study, we analyze the environmental management system integrated into the quality system of this company and discuss the effects on the organization and the economic issues. As a result of the EMS, emissions have been reduced effectively, and both the responsibility system and technology have become more controlled. The company chose to develop its environmental performance continuously, which is proved to have been performed successfully, considering its limited, one-year experience.
