In the three year experiment some antioxidative parameters of harvested and stored
red cabbage were estimated. The effects of applied nitrogen fertilizer form on
ascorbic acid (AA), total antioxidant activity (TAA), activity against hydroxyl
radical (HRA) and peroxidase (POD) activity were differentiated in each year of
the experiment. Long-term storage caused either decrease (2003/04) or slight
increase of AA (2004/05, 2005/06) in most treatments.
TAA rose significantly after three month storage, however, a drastic reduction
was observed in 2004/05. Activity against hydroxyl radical (HRA) determined in
the stored plants varied distinctly in respect to both treatments and individual
experimental seasons. Changes of the high POD activity affected by storage were,
in most cases, negligible.
