In 1 mm thick carrot root slices, stored for 3 days at 20°C a considerable accumulation of total phenols, chlorogenic acid and isocoumarin was observed, accompanied by increased activity of peroxidase and phenylalanine-ammonia lyase, as well as wound-ethylene evolution.

The plant tissue response to wound stress, followed by short-term ageing, depended on the previous post-harvest storage period of the roots. The highest metabolic activity of carrot root slices was observed when they were prepared from freshly harvested roots (November) and the lowest one in the case of three months storage of the roots (February). The sensitivity of carrot roots to stress from mechanical damage again rose in March but was less intensive than in autumn.
