【 摘 要 】

During 2007-2009, studies were undertaken to determine the effect of genetic factors, magnesium fertilisation and storage on the content of nitrates (V) and (III) in carrot roots. After harvest as well as after storage, the cultivar ‘Perfekcja’ was characterised by the lowest content of NO3− and NO2−, while the greatest amounts were found in cultivar ‘Flacoro’. Magnesium was applied in doses of 0, 45 and 90 kg MgO ha-1 - in the form of 3% spraying during the vegetation season. The research items were cultivars: ‘Berjo’, Flacoro’, ‘Karotan’, ‘Koral’ and ‘Perfekcja’.
