Wounding (shredding) of winter cabbage heads, followed by their short-term storage, brought about a decrease in soluble sugar (20°C and 5°C) and free amino acid (20°C) content. In the first year of the experiment a gradual increase in the ascorbic acid level was found in shredded cabbage (5°C), while in the following year the increase concerned only the samples treated with ammonium nitrate, irrespective of the storage temperature. An increase in thiocyanates within the injured tissue was noted at both storage temperatures, especially in the case of ammonium nitrate application.

Artificially evoked bruising of the heads induced less distinct changes in nutritional compounds, although an effect of wounding on ascorbic acid reduction in stored cabbage and on thiocyanates content was found. A higher sensitivity to mechanical damage was noted in plants treated with ammonium nitrate in comparison with urea.
